Breadboard version Bus Pirate and ST7920

BrianGriffin posted his Breadboard version Bus Pirate and ST7920 in the project log forum:

Over this weekend I cobbled up a breadboard version of Bus Pirate with the extra stuff I have from the drawer (the main chip PIC24FJ64GA002 is there too), dumped the bootloader and dumped the rest of the firmware with a dirt cheap USB->UART converter I have. It looked ghetto, but it worked on a Serial HD44780 LCD.

So, I have an idea. I have the ST7920 GLCD which I have a grudge on. It’s a fussy thing and it is pretty slow. Wrong command, you see garbled mess and garbage on screen. The serial was the worst – it couldn’t catch commands properly if you are unsure of its serial specifications. Since I have that franken-Bus Pirate, why not experiment on it?
