S08 SCI Transmit Issue

gregoryberardi — Thu, 08 Aug 2013 03:09:49 GMT

The attached code is what I'm using to try to send data out the sci tx port. The problem I am having is that I'm not seeing anything on the output (PTA3).

Any help is appreciated. Thank you in advance.

Yes, I did try the code. After changing the SCI2s to SCI0s I was unable to get it to work either. I noticed that there was a read of SCI0_S1 (which clears the flags) just before the while that waits for the flag to clear in the example that you linked. I put that in my code and it appears to work.

Thank you!
