Panasonic Touch Screen Connect with MCU Using Serial Port

01/03/2013 6:37 AM

Dear All,

I am doing a project using Panasonic TC with Renases MCU to control input & Output pins.I already written a code for MCU for communicating with hyperterminal to control I/O operation, using STX command.But the problem is TC command is starting with '?' for ex: TC one Switch command is ?01SRR0001016D,when I send this command no response,when I send a command with STX like STX?01SRR0003006E then i am getting output ,bec I already mentioned in the mcu program .

But I want the actual output when I send the ?01SRR0001016D this command bec the TC sending this command without having STX. so what shall I do.

What is the use of STX, if STX is not present what will be the result.Plz help me.

Regards

Jeffy

The question must be answered, is it true?

Re: Panasonic Touch Screen Connect with MCU Using Serial Port

now i can successfully send command from TC to mcu, but another problem is sending commands from mcu to tc, ie,i want to send a command like "?01SRW000615F"from mcu to TC for that I wrote a code, when testing in hyperterminal its working,but when connecting to TC its not working means no response from TC,but the same code in hyperterminal when pressing enter its passing to TC, its works.I dont know why MCU not sending to TC,

I found out one thing is when pressing enter in hyperterminal then only this command send to TC so add a'\r' in my program then also not working.

Normally MCU transmit one charater at a time,may be this is the issue,anyone have idea how to send a bunch of charaters at a time. Plz help me to find a solution.

All the commands I used in the program are right.
