Not sure if anyone has asked before.
Is there BSP for stm32L451 or other L4 family nucleo? also with RS232 turning driver?
I only have the L451 nucleo board with me,
I have already implemented the DFSDM drivers for PDM Microphone and able to playback to the internal dac with internal op-amp driving a balance armature speaker.
Now I am trying to implement the AWE Core to see what DSP I can do.
