Back at it, again!

So, I got my new P2 setup, connected to mi RPi 4, and I am having a hard time talking to the RPi 4.
My P2 is the 32MB, version, not sure how flexbasic will be able to handle that, but that is another discussion.

The main problem is getting the P2 setup to talk to the RPi 4. I tried FullDuplexSerial, jm_fullduplexserial, ... etc, and none seem to work. Not sure what my proplem is. I have the latest flexprop version setup on the RPi 4.

This should be a simple and straight forward setup, but it is turning out to be something else. I hope programming skils have deteriorated over the last few months.

  • Wait, you're trying to open a SmartSerial object on pins 62/63 while also using the flexbasic print statement that uses the same pins? What are you trying to achieve with that?
