56F8323 - serial communication

Started by Ravi...@geind.ge.com June 20, 2006
Hi All
We are using MC56F8323EVM. We are trying to do serial communication for last three days without any success.

We tried with both SCI0 and SCI1. We are able to receive data through serial communication, but not able to transmit anything. Please give us the complete procedure with sample application if any for transmission.

When we try to use the transmit pins of both port as general purpose and try to toggle the data, nothing is happening on the pins.
pin SS0 - TXD1 - PBO - portB-0 is staying as high always and
TXD0 - TC0 - PC6 0 portC-6 pin is staying low always.

We don't know, it is problem with hardware or we are missing some setting for making these pins GPIO. Please send us some info on these.

Thanks in advance.

Primary functions for those pins after reset are
either timer or SPI. You need to go to SIM_GPS to
configure those pins as SCI. you also need to
configure those pins as peripheral function in
GPIOx_PER registers.

I was in trubbels during a lot of time, too.
My solution was do nothing at code. The only trik was update the
codewarrior.
