Hi,
I am new to Coldfire and now having project to connect M5213 to LCD display (44780 compatible).  Is there any sample/application note I can look at?
 
Thanks.

I have the same problem. I´m using a M5213EVB board and want to connect a HD44780 compatible LCD. It would be nice if Freescale (or someone else) could provide an application note for the Coldfire, like the AN2940 for the HC08 processor. I´m primarly writing in C and using CodeWarrior.
 
Thanx.

OK, I've some info about how to do this. We can actually use shift register to convert serial bits coming from one of the GPIO to 8-bit data used for data, another pin to control the EN input, and one to control R/W*.
But I still doubt if connecting this 5V TTL register (and the LCD controller) to 3V level inputs on M5213 will work.

Any thought?

Hi,

You could use a level translator such as the ST2378E from STM wich is bidirectional and 15KV ESD protected.
