Plug in usb in both USB, miniUSB for STlink and macroUSB for pyboard.

This may cause by your board.

In my board, ADC(0).read() is work, and ADC(1).read() return 65535

ESP8266's ADC is 10-bit, so value is 0-1023.

you may read it as ADC(0).read()

Thanks for that. I still have some problems with the stm32l4 port. If I use `dfu-util -a 0 -s :mass-erase:force -D firmware.dfu` then I no longer get the dir() hard fault. I can also see that on first boot the LEDs stay on for longer (presumably initialising the file system). Unfortunately though W...

Hi @shaoziyang, I just tried uploading a port to the STM32L476 discovery board that I ordered and it almost seems to work - unfortunately Windows is having a problem with the USB device (Invalid Device Desciptor, Code 43). I can't see immediately why this would have any problems while the pyboard w...

Hi all, Have just started using micropython and very keen to work on a port for the STM32Lxxx series (the low power range for ST). Any ideas about why this would be a bad idea or things to watch out for? I created a cmake build of the pyboard v11 at https://github.com/stiege/cmake_micropython ; it ...

file copy speed is below 1KB/s.

After enable internal spiflash in STM32L476DISC board, pybflash disk size is enlarged, but speed is became very slow.

Does pyboard may use any pin to implement soft I2C? Because hardware I2C pin can not use.

MicroPython doesn't directly support this, but the reference Manual for the STM32F405 says that it is supported. So I think that you can make it work by using the stm module to read/write the registers directly to tweak the SPI mode. Here's an example of using the stm module to set the HDSEL bit in...
