Maybe with the new instructions (#TRISCx..#PORTx...)it can be done, but I have no time to look at it.

Thanks for de spam.... :(
I have thought about it and even with SPI it is not possible to do it.
Each character consists of 8bytes, so 26 char x 8 = 208 bytes and 10 digits x 8 = 80 bytes that is 288 bytes together.
A lookup table can only handle a maximum of 65 bytes and then you have to enter 288 hex codes.
The only possibility is to retrieve the data via RS232 / PC and for that you also need a PC program, all too much work.
Use an Arduino there are enough examples.
