Title: serial communication in H8S2633R
Post by: wowla on June 29, 2011, 10:20:02 PM

I have problem in writing the program code in the serial communication between the 2 H8S2633R. Basically, I want to send information from 1 of the processor to the other and I am send through a max232.

If both H8S2633R's are close together (short wires) then you do not need a to convert to RS232. the two H8S2633R's can be directly wired.
If they are far apart, more than a meter, then do you have a MAX232 of each H8S2633R?

Try getting one H8S2633R serial communications working to a PC com port, with the MAX232, using a terminal program. This is much easier to troubleshoot and debug. Once this works then connect the two H8S2633R's together.

Then how about the program code? I still cant make it communicate with the PC.
