Im trying to use as much of the GPIO pins at the bluepill STM32F103C8 64k flash. Is there any documentation or a list of build options to disable features such as the rx, tx pins JTAG and USB+ and USB-.
They are all listed as GPIO and port pins so I would assume they can do a high and low state.
I have managed to disable JTAG on a pure STM32F103C8 env in platformio.ini. But then I realized there is a dedicated env for the bluepill module and I needed to use it a stm32 real time libary. Problem is in this env I cant use the same functions/commands in setup to disable certain features. I also cant find any build flags to do that.
Thanks in advance for any and all help and suggestions where to look!
