Hello, good day,
I’m new to MCU programming. I have an STM32 based on the STM32L4+ series, and I’m using PlatformIO to try to make use of USB OTG to connect a USB keyboard for text input. I have a display connected where I want to see the text output. I’ve successfully set up the display, but its controller only has libraries for the Arduino framework. So, I want to use the Arduino framework to be able to use USB host to connect the keyboard, but I can’t find sufficiently comprehensive information to integrate this. For instance, I don’t know which PlatformIO directories to add the library to or how to do it. I’m sharing my .ini file and folder structure here in case anyone can help me.
