Resolved! STM32F103C8Tx can tx voltage too low and can clock speed
I am using truestudio and cubemx with STM32F103C8T6. I am trying to use canbus. If I connect the cantx and canrx pins on A12 and A11 (as shown in attached cubemx file), I get an output that looks like a can frame, but has peak voltage of 400mV.cubemx...
