MIPI LCD

DSI Interface definition

Radxa ROCK 3C has a 15 PIN CSI interface. The interface definition is as follows:

Currently supported MIPI DSI screens are:

• Radxa 8HD
• Radxa 10HD
• Raspberry Pi 7 inch screen

Radxa 10HD & Radxa 8HD

1. Connection Screen

Using Radxa 10HD and Radxa 8HD on RCOK 3C requires the use of specific DSI cables. The PIN pins are connected as follows:

Cable	40PIN
5V	PIN2(5V)
GND	PIN6(GND)
PWM	PIN7(PWM14_M0)
TPRST	PIN18(GPIO3_B2)
TPINT	PIN16(GPIO3_B1)
LCDRST	PIN1(3.3V)
GINT	NC

2. Use rsetup to enable Radxa 10HD overlay

If using Radxa 8HD need Enable Radxa Display 8HD

3. Power on and start

Before powering on, you need to confirm that the cables are connected correctly, connect the power supply to start the system, and you can start using Radxa 10HD.
