Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

The W25Q16 2MB SPI flash is connected to the SPI(3) bus on the VET6 and ZET6 boards. This script works, with a few modifications: https://github.com/manitou48/pyboard/blob/master/spiflash.py Replace: cs = pyb.Pin('X5') With either: cs = pyb.Pin('PB0') #VET6 cs = pyb.Pin('PB14') #ZET6 Replace: spi = ...

Quadcopter Fight Controller

There's a whole bunch of STM32F405 based quadcopter controllers out now. Might be a cheap alternative for portable projects that do not need a lot of IO. Onboard accelerometers and gyros could be useful. https://oscarliang.com/best-flight-controller-quad-hex-copter/ https://www.aliexpress.com/item/S...

Re: Drivers for Waveshare 2.13inch E-Ink display

My 2.9" Waveshare e-paper module arrived today. I'm a little late to the party. https://www.aliexpress.com/item/2-9inch-e-Paper-Module-296x128-2-9-E-Ink-display-SPI-interface-For-Raspberry-Pi/32811712396.html Looking forward to making it work with my Pyboard + ESPs. I went with the black/white versi...

Re: Using the ESP with a Ethernet Port through SPI

1) Yes. Ethernet and Wifi would use separate libraries. 2) Yes. The existing network module is very specific to ESP8266s Wifi firmware. You'll need something separate for Eth. 3) I am not sure about the ENC28J60 but there is a driver for the Wiznet 5x00 ethernet boards. eg. W5100, W5500 See: https:/...

Re: I2C LCD Library... Help!

You only need to upload: * esp8266_i2c_lcd.py * lcd_api.py The file esp8266_i2c_lcd_test.py gives you an example on how to use it. Those black PCF8574 I2C backpacks with blue trimpots are designed to work with all 16x2 displays, as shown in your first image. The ESP8266 version of this library was d...

Tabs vs Spaces vs Compiled

The pyboard has limited flash storage, when the SD card isn't being used. Taking this average size library as an example: https://raw.githubusercontent.com/adafruit/micropython-adafruit-tsl2561/master/tsl2561.py If I convert tabs to spaces I can store a tiny bit more. Wait... hear me out. Using spac...

Re: Is this ESP8266 module compatible with MicroPython

The ENOENTs were a bit confusing for me too at first.
It means Error NO ENTry (or Error NO ENTity)

You can safely ignore it, or just create an empty main.py file to make the warning go away.

Re: Is this ESP8266 module compatible with MicroPython

I can't see why it wouldn't be compatible. It looks like a typical "nodemcu" style ESP8266 dev board. Do you have the CP2102 driver installed? Try flashing it with a simple Arduino blink sketch to overwrite the AT firmware. You can't brick these devices, so worst case just erase the flash and start ...
