ESP32-P4: How to connect CSI_REXT / CSI_DEXT
The CSI_REXT and DSI_REXT pins on the ESP32-P4 are used for the ESP32-P4 internal current reference for the MIPI CSI (camera interface) or MIPI DSI (display interface) modules.
How to connect the CSI_REXT pin
- If you intend to use the MIPI CSI interface, you must add a
4.02kΩresistor fromCSI_REXTto GND. - If you will not use the MIPI CSI interface in this design, you may leave the
CSI_REXTpin floating
How to connect the DSI_REXT pin
- If you intend to use the MIPI DSI interface, you must add a
4.02kΩresistor fromDSI_REXTto GND. - If you will not use the MIPI DSI interface in this design, you may leave the
DSI_REXTpin floating
