Hi, thank you for your assistance. This is the first project I've worked on with this device and Processor Expert, so it is quite possible that I've misconfigured something.
I've tried a few bus clock frequencies, but the at the last build, the device was configured to run in high speed mode, using the internal clock. The Internal Bus clock frequency was 4.194304 MHz.
Under the Internal clock settings, the internal oscillator frequency is set to 32.768 kHz, with "Initialize trim value" set to 'no' -- so this may be the culprit? Would it be a better idea to use the external clock provided on the demo board?
I've attached screenshots of the Bean Inspector for both the CPU and AsynchroSerial beans, just to provide any additional information I missed here.
My goal is to send data to the board from the RS-232 port of my laptop. I'd be happy if I could achieve any fairly high baud rates (saw that 115200 baud was achieved the assembly example), at least 9600.
Thanks again for your time and help.
