Cisco DX80 touch screen control board
Hi everyone,
I'm planning to buy a Cisco DX80 for around €40 with the goal of reusing the display as a touchscreen for a Raspberry Pi.
My plan is to:Remove the Cisco motherboard.
Install a universal HDMI/LVDS LCD controller board to drive the LCD.
Reuse the original capacitive touchscreen if possible.
While taking a look inside, I found that the touch controller board is marked:
SiS9250B0GA3 + SiS9203_LGE_23"_V04
The board connects to the touch sensor via four ribbon cables and has a single 4-pin connector going to the Cisco motherboard.
My main question:
Does anyone know what interface that 4-pin connection uses?
Is it USB?
I²C?
UART?
Something proprietary?
If it's USB, there's a good chance I can connect it directly to the Raspberry Pi and keep the original touchscreen working.
Also, does anyone know the exact LCD panel model used in the DX80?
If anyone has disassembled I'd really appreciate any information.
Thanks a lot!
