The pcf8814_lcd protocol decoder supports Philips PCF8814 (65 x 96 pixels matrix LCD driver) based displays.
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:
| Probe | LPC1343 chip |
|---|---|
| 1 (black) | CS# (PIO2_1 / DSR) |
| 2 (brown) | SCK (PIO2_11 / SCK0) |
| 3 (red) | SDA (PIO0_9 / MOSI0) |
| 4 (orange) | RST# (PIO2_2 / DCD#) |
