Driver usb 2.0 serial arduino11/30/2022 The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board. I simply use a Chinese ST-Link V2 clone for programming. The chip also acts as a full speed USB 2.0 device, using standard USB COM drivers. The first thing I do when starting with a new Blue Pill is to unlock the flash and probably also erase / overwrite the bootloader accordint to the hands-on primer from Pandafruits (Real nice introduction into linker scripts and such). I tested all three very briefly by typing some characters into Minicom and a loopback wire on the Blue Pill.Īll 3 Serial ports work, and they all three go through the same USB cable to my Blue Pill.ĭata echoing stopped immediately when a loopback wire was disconnected, so I am sure that the data ended up at the right UsART.Īccording to the notes I made I had to put an 1k8 resistor between PA12 and 3V3 to get my PC (with Sitecom hub) to recognise the Blue Pill Device. It added 3 extra serial ports to my Linux box. This project worked without modifications to the source code for me. I am also quite a beginner with STM32 and I am quite overwhelmed with al the options for STM32.Īs a sort of random test project I compiled, flashed and experimented a bit with:
