BPI-216 Serial LCD module

[crematory]

Hi

I was wondering if any one has tried to make his own serial LCD interface like BPI-216 serial LCD module.

I need to know how I can do that in deed.

Thanks

SERIN

LCDOUT

I'm with Darrel Taylor on this. I created a serial to VFD interface once.

Grab the datasheet for the LCD in one hand and the datasheet for the serial LCD you are modeling and start programming.

Thanks guys for suggestions you made...

How can I receive these things from the sending PIC as an example:

Serout Portb.0, N9600,[$FE,1,"This is the serial LCD Project !!"]


Thanks

If you have windows you could use hyper terminal or you could utilize someone elses lcd application.

For best performance, connect your LCD to your chosen PIC in 8-bit Data mode, and use a PIC with a hardware USART onboard. You can pick up byte at a time from the receive register and immediately output to LCD. The PICs DATASHEET gives explicit instructions on how to drive the USART. I would not use HSERIN, and certainly not any of the software options like SERIN or SERIN2 etc. Since the timing is not critical for anything other than the USART, pick a Baudrate friendly xtal (like 22.1184MHz or 11.0592MHz) that gives zero errors at the popular baudrates. You should easily handle at least 56kb using this method (not that your LCD would be able to sensibly display that fast - it'll handle it, you just won't see it!).

PS. I've mentioned before I don't do off-list requests.
