I have a C5402 DSK, and I'm trying to do a serial communication using
the DB9 connector to a microcontroller(AT89C52). The microcontroller can communicate serially with my computer perfectly, and so does the TMS320VC5402 also can communicate serially with my computer perfectly. The problem is, using the same UART configuration(9600 baud, 8 bit data, 1 stop bit, no parity), why can't my TMS and my microcontroller communicate with each other? Can anyone tell me some possible solutions or informations what may cause this problem? Thank you. |

Marcelino Just a quick guess is that you may need a null modem crossover.
