Building for it

A project is made for one toolchain, picked when you start it. For this board you can use one of the four:

Toolchain
Arduino (C++)	Every board, every widget and every peripheral here. The most control, and the most to set up. Start a project
MicroPython	The MicroPython export has not been built for this chip yet. It is written for the ESP32, S2, S3, C3 and C6.
ESPHome	The ESP32-P4 is only useful here with a MIPI-DSI panel, which this export does not write yet.
ESP-IDF (C)	The ESP-IDF export does not load the GSL3680's firmware or read it yet. The Arduino export does both.

Wi-Fi: the ESP32-C6 beside the P4

The ESP32-P4 has no radio. This board’s Wi-Fi is an ESP32-C6 on the P4’s SDIO lines running Espressif’s ESP-Hosted, which has to be the release the ESP32 core was built with (2.12.11 for the core LCD Wizard exports for). A C6 as it leaves the factory may run an older one: the serial port then says ESP-Hosted of an unknown version, and Wi-Fi can fail or freeze the board as it starts. Update my C6 writes 2.12.11 to it from the browser, with no Wi-Fi and no password. Why, and how to update the C6.

An older C6 may have to be flashed by hand. One whose ESP-Hosted is too old to take an update over the link refuses it, and nothing is written; it is then flashed through its own UART, as the board’s maker describes (how).

Also on the board

I2C (GPIO 7 / 8: touch, codec) - SDA GPIO 7, SCL GPIO 8
SDCard - SD card, CLK GPIO 43, CMD GPIO 44, D0 GPIO 39, D1 GPIO 40, D2 GPIO 41, D3 GPIO 42
The TF card slot, on SDMMC 4-bit (CLK 43, CMD 44, D0-D3 39-42), as Guition's BSP has it. Guition power it from the chip's LDO channel 4.
WiFiCoprocessor - Wi-Fi co-processor, CLK GPIO 18, CMD GPIO 19, D0 GPIO 14, D1 GPIO 15, D2 GPIO 16, D3 GPIO 17, RST GPIO 54
The ESP32-C6 beside the P4 is this board's Wi-Fi, on SDIO CLK 18, CMD 19, D0-D3 14-17 and its CHIP_PU on GPIO 54 (reset low): Guition's schematic and the board's own stock firmware (ESP-Hosted host 2.11.0, slot 1, 4-bit, 40 MHz) agree, and they are the ESP32 core's own lines for the P4. It must run ESP-Hosted of the core's release (the README says how to tell).

The preset adds these to the Hardware tab with the board, so a sensor can go straight onto the connector.

Check your revision. Nobody at LCD Wizard has had this board: the export for it compiles and has not been seen on the panel. Every pin and setting is from Guition's own BSP for it: panel reset GPIO 27, backlight GPIO 23 (Guition drive it at 20 kHz), the JD9365 started with Guition's own table at 60 MHz, two lanes at 1500 Mbps, hsync 20/20/40 and vsync 4/8/20. If the panel stays dark with the backlight lit, choose "Type 1, 800x1280" as the start-up sequence on the Display tab, at 750 Mbps a lane: that is GFX Library for Arduino's own definition of the board, one row different. Touch is the board's GSL3680 (I2C 0x40 on GPIO 7/8, reset 22, interrupt 21), loaded with Guition's own firmware at every start; the serial log says whether it runs. Guition's driver also runs Silead's point-tracking code on every read, which the export leaves out: one finger is read, as the chip reports it, scaled from the chip's own 1648 x 880 (it reports landscape on this portrait glass), X and Y swapped and X inverted, as measured on a member's board. If touches land in the wrong place, the swap and invert settings on the Touch tab are where to correct it. The ES8311 speaker codec (MCLK 13, BCLK 12, LRCK 10, data 9, amplifier GPIO 20) is in the kit and off; its address 0x18 is the chip's default, not in Guition's code. A design on this preset builds for an ESP32-P4 before revision 3; if the upload reports revision 3 ("revision v3.1"), choose that under Hardware > Board > Chip revision. The ESP32-C6 is the board's Wi-Fi, on the pins its schematic and its stock firmware both give. Not driven: the microphone and the camera connector.

Designing for it in LCD Wizard

Choose Guition JC8012P4A1 10.1 inch ESP32-P4 (JC8012P4A1C_I_W_Y1) on the Hardware tab (or use the button above) and every pin on this page is filled in. The export writes the sketch, lcd_pins.h, the GFX Library for Arduino configuration, lv_conf.h and platformio.ini - a project that builds for this board as it comes.
The GSL3680 is capacitive and needs no calibration. The firmware resets it and checks it answers on every boot.
The backlight is dimmable: give a slider or a button a Set backlight action.
With PSRAM the LVGL memory pool can live there, leaving internal RAM for everything else.
The MIPI-DSI panel stays on while settings or files are saved: the Arduino export keeps the frame running through flash writes, which otherwise blank an ESP32-P4 screen.
Screens are designed for 800 x 1280 px in either orientation, with LVGL 9 or LVGL 8.
