connecting TOUCHSCREEN AND pic16F877a

[slurp.lolipop]

I purchased a Panasonic Programmable Display (GT01) whic is a touchscreen device.

I would like to to connect it to a PIC16F877a.

Q1) how can i do that?

the concept is for communication between the 16F877a and GT01.
With 16F877a as the domain controlling (sending data) to the GT01 and display it out.

Please help me. I don't know what suitable protocol to use for this. USART? UART? I2C?

Moreover, the cables that are attached to the GT01 are rs232 and rs232C.

Q2) if I do not use that specific model GT01. Are there any other touchscreen connection with 16F877a projects being done before?

Hope to hear from kind electro-techians soon.

cheers,

If the display has RS232 then you need to use the UART, but check the logic levels as you may need a RS232 driver chip.

I've been using this. Its looking good..

good-day Ian,
what do you mean " but check the logic levels as you may need a RS232 driver chip."
is that a technical/condition must for uart?
