Overzicht:
Eerste ervaringen met NodeMCU, besteld 25 okt ’18. Dit wordt HeRoESP1, mac adres cc:50:e3:4a:55:37, vast IP adres werkt.

Default maakt ESP een AccessPoint ESPxxyyzz met laatste 3 nibbels van mac adres. ESP01 besteld bij MiniInTheBox, is in april ’19 gebruikt met relay module voor domotica. In maart + april ’19 nieuwe bestelling AliExpres gedaan, zie tabel hieronder. mDNS werkt, voor vast IP adres, dit met WiFi.config (Zie HenkLIN_SOP_Server) of in Ziggo modem DNS reservering op MacAddress, bijv voor IP adress 192.168.178.99, werkt.

ESP32-WRoom-32u of 32d heeft meer (io) pins dan een gewone W-ROOM. Laatste nieuwste is ESP32-S3.

 Misschien ooit nog een Witty ESP bestellen?

Samenvatting

Sep 23:Veel geleerd bij testen ESP Nr 32. Dit is een ESP-12E en bij booten kwam er een ‘standaard’ output zoals bij meerdere ESP. Dit begint met:

ets Jun  8 2016 00:22:57 en dan rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) etc.

Daarna nog meer tekst en aan het eind strooi (troep) karakters. Dit had ik wel vaker gezien maar na uitzoeken blijkt dat de tekst ‘est Jun’ etc van de ESP boootloader is en dat de ‘strooi’ karakters aan het eind, van het echte ‘interne’ programma is. De ESP bootloader heeft een andere baudrate dan het echte programma. Dit heeft iets te maken met het kristal op de print. De bootloader heeft een baudrate van 74880 en het programma werkt op 115200. Met 74880 zie je dus de bootloader tekst en met 115200 de firmware output. Output bekeken met ReadCom.ps1, een zelf gemaakt Powershell script. Let op dat deze niet in de Powershell ISE kan draaien, er is dan geen console. Je moet een Powershell window maken.

ESP Nr 33, is een ESP32-C3 N16-R8 en heeft micropython als firmware en een NeoPixel LED op board aan pin 48 (GPIO_48).

ESP Nr 32 heeft een CH340 driver, de laatste versie (3.8) werkt niet, geeft permission errors. Versie 3.5.2019 doet ’t wel goed, zie CH441SER.exe, heb ik gedownload.

Verdere info:

NodeMCU ESP8266 van AliExpress, 30 okt ’18 (espNr 5), is experiment board met CP2101 serial converter, kost Euries 2,45.

NodeMCU is standaard met LUA, een interpreter. Algemene indruk op Internet is dat LUA interpreter wel makkelijk is, maar ‘traag’en instabiel.

Arduino IDE en bijbehorende taal is alternatief, meer low-level, in C(++) en met goede libraries.

In LUA doe je iets als: gpio.mode(0,gpio.OUTPUT); gpio.write(0,0)

In arduino: int LED_Pin = D0; void setup() { pinMode(LED_Pin, OUTPUT); }

void loop() {   digitalWrite(LED_Pin, LOW); delay(3000); digitalWrite(LED_Pin, HIGH); delay(1000); }

NodeMCU ESP8266 heeft 80MHz cpu,  2 spi poorten, 1 ervan is voor spi flash system, andere SPI poort is wel vrij.

Opvolger ESP8266 is ESP32, deze heeft snellere 160MHz cpu, 150Mbps WiFI, bluetooth + hall sensor en touch sensitive pins en 4 SPI channels.

ESP32 types: DOIT ESP DEVKIT, Xiuxin ESP32 Dev board, Adafruit feather, Sparkfun ESP32 thing, WEMOS EPS32 met battery holder, ESP32 met OLED, ESP32 SX1278 met LoRa. ESP32S heeft 38 IO Pins, is dit hetzelfde als de DEVKITC?

NodeMCU/ESP identificatie:

Open gitbash shell op C:\ESP8266\ESPlorer en doe ./ESPlorer. Laatste selectie is COM8, 115200 baud. Kies rechts Open, daarna links bij AT kies je GMR (is at identificatie). Dan links onderin bij WiFi Station kies je CIPSTAMAC? en dan zie je macAddress.

Eerste ervaringen met NodeMCU HeRoESP1:

Op breadboard gezet, micro-usb kabel aangesloten, apparaatbeheer zegt dat de drivers missen. Drivers als zip gedownload van https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers.

Zip uitgepakt in download en in apparaatbeheer de drivers geinstalleerd.

Met putty geconnect (serial com3, 9600 baud) en het werkt! Output van putty is:

ESP8266Flasher van nodemcu gedownload, deze deed ’t wel, duurde een minuut of 10. Nu is de output van putty, bij 115200 baud:

In ESPlorer snippet gemaakt, deze laat de LED op het board branden met:  gpio.mode(0,gpio.OUTPUT); gpio.write(0,0)

Dan met Arduino IDE gedaan. Is andere taal (Arduino C++) maar werkt ook. Default baudrate is 9600, 256000 gaat ook, alleen mis je soms chars in Serial monitor, 115200 is optimaal. Projectjes maken gaat redelijk simpel. HenkLIN SIP Met SPI gebruikt als SOP (Output) met 32 LEDs, gaat goed. ESP maakt default een WiFi AP genaamd ESP4a5537, dus laatste 3 bytes van mac adres. Is uit te zetten door alleen station mode bij wifi.begin te zetten. Zelf HeRoESP1 AP gemaakt met wachtwoord I3d3r33n. Ook begonnen met Arduino library voor MCP23S17 SPI controle.

 

ESP01 gebruikt voor Relay module test. ESP01 van MiniInThebox, besteld 1 dec 2015. Mac address 5c:cf:7f:0b:8f:be, nog geen vast IP address.

ESP01 moet in ‘programming mode’staan om te kunnen proggen. Dit doe je door Pin5 (GPIO0) en Pin 1 (Gnd) met elkaar te verbinden.

GPIO1 niet gebruiken voor LED blink, want deze is TX dus zie je geen serial output. Baudrate 115200 is OK.

Pin 1=GND, Pin 2=GPIO1/TXD, Pin3=GPIO2, Pin4=CH_PD (Enable), Pin5=GPIO0, Pin6=Reset, Pin7= GPIO3/RX, Pin8=Vcc

Best Pins to Use – ESP8266

One important thing to notice about ESP8266 is that the GPIO number doesn’t match the label on the board silkscreen. For example, D0 corresponds to GPIO16 and D1 corresponds to GPIO5. The following table shows the correspondence between the labels on the silkscreen and the GPIO number as well as what pins are the best to use in your projects, and which ones you need to be cautious.

The pins highlighted in green are OK to use. The ones highlighted in yellow are OK to use, but you need to pay attention because they may have unexpected behavior mainly at boot. The pins highlighted in red are not recommended to use as inputs or outputs.

GPIOs connected to the Flash Chip: GPIO6 to GPIO11 are usually connected to the flash chip in ESP8266 boards. So, these pins are not recommended to use.

Pins used during Boot: The ESP8266 can be prevented from booting if some pins are pulled LOW or HIGH. Pin states on BOOT:

·          GPIO16: pin is high at BOOT ; GPIO0: boot failure if pulled LOW; GPIO2: pin is high on BOOT, boot failure if pulled LOW

·          GPIO15: boot failure if pulled HIGH; GPIO3: pin is high at BOOT; GPIO1: pin is high at BOOT, boot failure if pulled LOW

·          GPIO10: pin is high at BOOT; GPIO9: pin is high at BOOT

Pins HIGH at Boot: There are certain pins that output a 3.3V signal when the ESP8266 boots. This may be problematic if you have relays or other peripherals connected to those GPIOs. The following GPIOs output a HIGH signal on boot:

·          GPIO16 + GPIO3 + GPIO1 + GPIO10 + GPIO9

Additionally, the other GPIOs, except GPIO5 and GPIO4, can output a low-voltage signal at boot, which can be problematic if these are connected to transistors or relays. You can read this article that investigates the state and behavior of each GPIO on boot.

GPIO4 and GPIO5 are the most safe to use GPIOs if you want to operate relays.

Analog Input: The ESP8266 only supports analog reading in one GPIO. That GPIO is called ADC0 and it is usually marked on the silkscreen as A0.

The maximum input voltage of the ADC0 pin is 0 to 1V if you’re using the ESP8266 bare chip. If you’re using a development board like the ESP8266 12-E NodeMCU kit, the voltage input range is 0 to 3.3V because these boards contain an internal voltage divider.

On-board LED: Most of the ESP8266 development boards have a built-in LED. This LED is usually connected to GPIO2.

The LED is connected to a pull-down resistor, so when you send a HIGH signal the LED turns off.

RST Pin: When the RST pin is pulled LOW, the ESP8266 resets. This is the same as pressing the on-board RESET button.

GPIO0: When GPIO0 is pulled LOW, it sets the ESP8266 into bootloader mode. This is the same as pressing the on-board FLASH/BOOT button.

GPIO16: GPIO16 can be used to wake up the ESP8266 from deep sleep. To use this wake up , GPIO16 should be connected to the RST pin.

I2C: The ESP8266 doens’t have hardware I2C pins, but it can be implemented in software. So you can use any GPIOs as I2C. Usually, the following GPIOs are used as I2C pins:

·          GPIO5: SCL + GPIO4: SDA

SPI: The pins used as SPI in the ESP8266 are:

·          GPIO12: MISO + GPIO13: MOSI + GPIO14: SCLK + GPIO15: CS

PWM Pins: ESP8266 allows software PWM in all I/O pins: GPIO0 to GPIO16. PWM signals on ESP8266 have 10-bit resolution.

Interrupt Pins: The ESP8266 supports interrupts in any GPIO, except GPIO16.

Versie met 36 Pins (met een antenne recht tegenover de USB zijde):

ESP32 Peripherals, they include:

The ADC (analog to digital converter) and DAC (digital to analog converter) features are assigned to specific static pins. However, you can decide which pins are UART, I2C, SPI, PWM, etc – you just need to assign them in the code. This is possible due to the ESP32 chip’s multiplexing feature.

Although you can define the pins properties on the software, there are pins assigned by default as shown in the following figure (this is an example for the ESP32 DEVKIT V1 DOIT board with 36 pins – the pin location can change depending on the manufacturer).

Additionally, there are pins with specific features that make them suitable or not for a specific project. The following table shows what pins are best to use as inputs, outputs and which ones you need to be cautious.

Input only pins

GPIOs 34 to 39 are GPIO–input only. They don’t have internal pull-ups or pull-down resistors. They can’t be used as outputs:

 

GPIO 34

GPIO 35

GPIO 36

GPIO 39

SPI flash integrated on the ESP-WROOM-32

GPIO 6 to GPIO 11 are exposed in some ESP32 development boards. However, these pins are connected to the integrated SPI flash on the ESP-WROOM-32 chip and are not recommended for other uses. So, don’t use these pins in your projects:

 

GPIO 6 (SCK/CLK)

GPIO 7 (SDO/SD0)

GPIO 8 (SDI/SD1)

GPIO 9 (SHD/SD2)

GPIO 10 (SWP/SD3)

GPIO 11 (CSC/CMD)

The pins marked OK are ok to use. The ones highlighted in yellow are OK to use, but you need to pay attention because they may have unexpected behavior mainly at boot. The pins highlighted in red are not recommended to use as inputs or outputs.

Capacitive touch GPIOs

The ESP32 has 10 internal capacitive touch sensors. These can sense variations in anything that holds an electrical charge, like the human skin. So they can detect variations induced when touching the GPIOs with a finger. These pins can be easily integrated into capacitive pads, and replace mechanical buttons. The capacitive touch pins can also be used to wake up the ESP32 from deep sleep.

Those internal touch sensors are connected to these GPIOs:

T0 (GPIO 4)

T1 (GPIO 0)

T2 (GPIO 2)

T3 (GPIO 15)

T4 (GPIO 13)

T5 (GPIO 12)

T6 (GPIO 14)

T7 (GPIO 27)

T8 (GPIO 33)

T9 (GPIO 32)

Learn how to use the touch pins with Arduino IDE: ESP32 Touch Pins with Arduino IDE

Analog to Digital Converter (ADC)

The ESP32 has 18 x 12 bits ADC input channels (while the ESP8266 only has 1x 10 bits ADC). These are the GPIOs that can be used as ADC and respective channels:

ADC1_CH0 (GPIO 36)

ADC1_CH1 (GPIO 37)

ADC1_CH2 (GPIO 38)

ADC1_CH3 (GPIO 39)

ADC1_CH4 (GPIO 32)

ADC1_CH5 (GPIO 33)

ADC1_CH6 (GPIO 34)

ADC1_CH7 (GPIO 35)

ADC2_CH0 (GPIO 4)

ADC2_CH1 (GPIO 0)

ADC2_CH2 (GPIO 2)

ADC2_CH3 (GPIO 15)

ADC2_CH4 (GPIO 13)

ADC2_CH5 (GPIO 12)

ADC2_CH6 (GPIO 14)

ADC2_CH7 (GPIO 27)

ADC2_CH8 (GPIO 25)

ADC2_CH9 (GPIO 26)

Note: ADC2 pins cannot be used when Wi-Fi is used. So, if you’re using Wi-Fi and you’re having trouble getting the value from an ADC2 GPIO, you may consider using an ADC1 GPIO instead, that should solve your problem.

The ADC input channels have a 12 bit resolution. This means that you can get analog readings ranging from 0 to 4095, in which 0 corresponds to 0V and 4095 to 3.3V. You also have the ability to set the resolution of your channels on the code, as well as the ADC range.

The ESP32 ADC pins don’t have a linear behavior. You’ll probably won’t be able to distinguish between 0 and 0.1V, or between 3.2 and 3.3V. You need to keep that in mind when using the ADC pins. You’ll get a behavior similar to the one shown in the following figure.

Digital to Analog Converter (DAC)

There are 2 x 8 bits DAC channels on the ESP32 to convert digital signals into analog voltage signal outputs. These are the DAC channels:

RTC GPIOs

There is RTC GPIO support on the ESP32. The GPIOs routed to the RTC low-power subsystem can be used when the ESP32 is in deep sleep. These RTC GPIOs can be used to wake up the ESP32 from deep sleep when the Ultra Low Power (ULP) co-processor is running. The following GPIOs can be used as an external wake up source.

RTC_GPIO0 (GPIO36)

RTC_GPIO3 (GPIO39)

RTC_GPIO4 (GPIO34)

RTC_GPIO5 (GPIO35)

RTC_GPIO6 (GPIO25)

RTC_GPIO7 (GPIO26)

RTC_GPIO8 (GPIO33)

RTC_GPIO9 (GPIO32)

RTC_GPIO10 (GPIO4)

RTC_GPIO11 (GPIO0)

RTC_GPIO12 (GPIO2)

RTC_GPIO13 (GPIO15)

RTC_GPIO14 (GPIO13)

RTC_GPIO15 (GPIO12)

RTC_GPIO16 (GPIO14)

RTC_GPIO17 (GPIO27)

PWM

The ESP32 LED PWM controller has 16 independent channels that can be configured to generate PWM signals with different properties. All pins that can act as outputs can be used as PWM pins (GPIOs 34 to 39 can’t generate PWM).

To set a PWM signal, you need to define these parameters in the code:

Learn how to use ESP32 PWM with Arduino IDE: ESP32 PWM with Arduino IDE

I2C

The ESP32 has two I2C channels and any pin can be set as SDA or SCL. When using the ESP32 with the Arduino IDE, the default I2C pins are:

If you want to use other pins, when using the wire library, you just need to call:Wire.begin(SDA, SCL);

Learn more about I2C communication protocol with the ESP32 using Arduino IDE: ESP32 I2C Communication (Set Pins, Multiple Bus Interfaces and Peripherals)

SPI

By default, the pin mapping for SPI is:

SPI

MOSI

MISO

CLK

CS

VSPI

GPIO 23

GPIO 19

GPIO 18

GPIO 5

HSPI

GPIO 13

GPIO 12

GPIO 14

GPIO 15

Interrupts

All GPIOs can be configured as interrupts.

Learn how to use interrupts with the ESP32:

Strapping Pins

The ESP32 chip has the following strapping pins:

These are used to put the ESP32 into bootloader or flashing mode. On most development boards with built-in USB/Serial, you don’t need to worry about the state of these pins. The board puts the pins in the right state for flashing or boot mode. More information on the ESP32 Boot Mode Selection can be found here.

However, if you have peripherals connected to those pins, you may have trouble trying to upload new code, flashing the ESP32 with new firmware or resetting the board. If you have some peripherals connected to the strapping pins and you are getting trouble uploading code or flashing the ESP32, it may be because those peripherals are preventing the ESP32 to enter the right mode. Read the Boot Mode Selection documentation to guide you in the right direction. After resetting, flashing, or booting, those pins work as expected.

Pins HIGH at Boot

Some GPIOs change its state to HIGH or output PWM signals at boot or reset. This means that if you have outputs connected to these GPIOs you may get unexpected results when the ESP32 resets or boots.

Enable (EN)

Enable (EN) is the 3.3V regulator’s enable pin. It’s pulled up, so connect to ground to disable the 3.3V regulator. This means that you can use this pin connected to a pushbutton to restart your ESP32, for example.

GPIO current drawn

The absolute maximum current drawn per GPIO is 40mA according to the “Recommended Operating Conditions” section in the ESP32 datasheet.

ESP32 Built-In Hall Effect Sensor

The ESP32 also features a built-in hall effect sensor that detects changes in the magnetic field in its surroundings.

23 Nov 2020, nieuwe NodeMCU WROOM-32U, AliExpress, wordt espNr 15 (new)

Met Arduino IDE gebeurde niks, esplorer ook niet, COM poort kwam wel (COM3, 115200 baud). In ESPlorer DTR en RTS aan, output verscheen (zie onder), in Arduino IDE later ook, maar dan moet je m eerst aansluiten en dan op de Reset button drukken. Device werkt dus goed, gaat ESP Nr 15 vervangen, deze is stuk

Begin januari 2021:ESP Nr 18 was stuk (in 3D printerkast,HeRoTempControl) vervangen door ESP Nr 16. Deze gaf out-of-the-box USB error meldingen en halve opstartmeldingen. Toch geprogged met HeRoTempControl V0.11, ging goed.

 

22 jan 2021, Vervanger van ESP Nr 18 ontvangen. Aan USB gehangen en met Seriele Monitor in Arduino IDE bekeken.Na Reset knop, kwam:

Welcome to MicroPython on the ESP32!

 

For generic online docs please visit http://docs.micropython.org/

 

For access to the hardware use the 'machine' module:

 

import machine

pin12 = machine.Pin(12, machine.Pin.OUT)

pin12.value(1)

pin13 = machine.Pin(13, machine.Pin.IN, machine.Pin.PULL_UP)

print(pin13.value())

i2c = machine.I2C(scl=machine.Pin(21), sda=machine.Pin(22))

i2c.scan()

i2c.writeto(addr, b'1234')

i2c.readfrom(addr, 4)

 

Basic WiFi configuration:

 

import network

sta_if = network.WLAN(network.STA_IF); sta_if.active(True)

sta_if.scan()                             # Scan for available access points

sta_if.connect("<AP_name>", "<password>") # Connect to an AP

sta_if.isconnected()                      # Check for successful connection

 

Control commands:

  CTRL-A        -- on a blank line, enter raw REPL mode

  CTRL-B        -- on a blank line, enter normal REPL mode

  CTRL-C        -- interrupt a running program

  CTRL-D        -- on a blank line, do a soft reset of the board

  CTRL-E        -- on a blank line, enter paste mode

Met micropython script het mac adress opgehaald (zie script ESP32MicroPythonGetMac.ps1, in documenten/pc stuff):

$Script:port.WriteLine("import network`r")

         $Script:port.WriteLine("import ubinascii`r")

          $Script:port.WriteLine("mac=ubinascii.hexlify(network.WLAN().config('mac'),':').decode()`r")

          $Script:port.WriteLine("mac`r")

Output is dan: 'f4:12:fa:ce:d7:38'

24 sep 23, ESP Nr 31, een Lolin Wemos ESP32 S2 mini met USB-C. Werkt raar, het flash en reset btn.

Reset btn laat com poort verdwijnen en weer komen, dus als je bij boot output print, mis je de eerste output. Dus geen firmware bootloader output kunnen zien. HelloWorld mbv VSCode geflasht, werkt wel maar omdat de COM poort steeds verdwijnt is output moeilijk te catchen. Daarom laat HelloWorld nu om de 10 seconden output zien.
