Using Nokia BB5 LCD with PIC32


Short brief :
source : http://www.elektroda.pl/rtvforum/topic1344700.html
help :
– Leadis reference to LDS285 : http://www.trulydisplays.com/tft/driveric/IC%20Spec%20LDS285.pdf
– Microchip toolz & CPUs
objective : using Nokia’s LCD with Microchips CPUs

Finally, objective achieved 🙂

Findings :
“Modern” BB5 Nokias are using MIPI’s MeSSI bus between MPU and LCD controller.
Although obtaining MeSSI specification from MIPI can be hard for hobbyist, bus is 100% compatible with popular 8080 Interface = Mode2 Parralel Master Port in PIC32… 🙂
LCDs of E51 or E65 are pin-to-pin compatible, many others (BB5-style) has the same pinout and connector.

Pros:
– 320x240x24bit LCDs
– integrated controller with DDRAM (no need to waste MPU RAM for storing display data)
– cheap solution (~8-10$ for a piece of glass)
– simple interface, really 🙂

Cons:
– such LCD require relatively high computational power

more info incoming soon…
