#163153 - how to debug this serial communication |
Hi all,
I'm using AT89C5131 to do a project, and I need it to communication with MATLAB. During the debugging, I can send signal from 8051 to MATLAB, however when I sent signal from MATLAB to 8051, I can see the signal when I was connecting an osciloscope directly on the PC side serial line, however I can't receive any signal or only a bit of the whole byte when checking the uC side serial line. Could anyone with experience give me some suggestions? Thanks! |
