I am working from the PDL guide to initialize the uart on the CM0P for a dual app solution.
The guide mentions txBuffer = CMD_START_TRANSFER; but I can't find any reference to what the CMD_START_TRANSFER is, the guide also has no other explanation of this description . What is this?
Below is the configured setup, I compared it to the code the device configurator generates, and it seems to be correct. However, I am getting Null char being sent out. If a enable the interrupt the processor stops functioning, and I don't see why .
Attached is the source file , I am just trying to send out one byte at a time and receive one byte at a time on interrupt
Could anyone please have a look and let me know what am i missing?
Resolved the character transfer issue ,
I would still like to know what the CMD_START_TRANSFER is referred to in the documentation. If anyone has some advise on this?
