Hi,
Re: TMS320F28004x Microcontroller Workshop.
I am working with the Lab 11 titled sci_ex1_echoback.c. In the text under the heading "Lab 11: C2000Ware SCI Echoback Example, Objective" it mentions that "SCI-A is mapped to the virtual COM port ... using GPIO28 and GPIO29. I can tell that the program is running correctly due to the console output which does indeed echo the characters I type. I was also expecting to see electrical signals on GPIO28 and GPIO29 but none are present, I was able to detect a signal on the TXD of J101 however. My question is whether there should also have been signals on GPIO28 and GPIO29 and if so what might be inhibiting them.
Thanks,
Steve
