I set the clock to what should be 100mhz i believe. And I added the pin number from the datasheet to the stm32f401.csv file. No love.
The TX from the MCU seems to be sitting around +/-1vdc so I'm thinking it's not properly configured. Looking at the nucleo 144 board schematics RX/TX to the STLink are indeed the same PA2 and PA3.
This is my first real dive into the world of stm32. While I've used pic and atmegas this stuff is new to me. Any other thoughts on stuff I could look into?
