Hello,
I am trying to define three serial ports for the WeAct STM32H562 and deeply confused as to what port type pins assignment to select from the ST documentation on the chip.
Some serial are designated as UARTx, some are LPUARTx, some are USARTx.
According to the doc LP is low power and USARTx are NRZ asynchronous.
Only way I have been able to figure out where ARTx_TX comes off the board is to define it as HardwearSerial ,send data to it and go along the board pin with my scope until I find the signal.
There has to be a better way, there has to be some science or logic to it not just what is seemingly random.
Any ideas please?
