Hardware

rOket Nokia 1200 display

The display/nokia_1200/r0ket directory in sigrok-dumps contains a set of example captures of the protocol of a Nokia 1200 cell phone display.

The display is a monochrome LCD with 96x68 pixels. It uses the Philips PCF8814 "65 x 96 pixels matrix LCD driver".

The display is attached to the r0ket eval board / conference badge. It is controlled from the NXP LPC1343 ARM controller on that board.

The logic analyzer used was a Saleae Logic (at 16MHz).

Probe setup:

2 (brown) SCK (PIO2_11 / SCK0)
