Well simply put, developement is not always easy, sometimes I am stuck with software, sometimes I had enough of soldering wires, and it happens that I have to search for a component.
Currently I am working at a small 1.8" TFT LCD circuit, I use PIC 18f24j10, not that it would be particulary good for this purpose, I simply have some around, and never used them.
The memory is 16K only, and that is not enough even for a single full image.
Tonight I spend some hours searching for 32K EEPROM, which I had on the board previously, then removed again, but reconsidered to have it on board. I found it, finally!
And I changed the font data so I can built it as .hex file with MPLAB X + MPASM, and then write to EEPROM using my GAL programmer. Too much effort to add this to PIC program memory, and then move manually.
I hope my GAL programmer can use the 24LC256! But I will figure out about this very soon.
