Guition JC8012P4A1

Hey,

I bought https://nl.aliexpress.com/item/1005008789890066.html screen, a 10.1-inch ESP32P4. I was already running an lvgl project on a previous screen but wanted to go a little bigger and move away from a fragile developer board, this seemed ideal.

Now my project is in landscape and the board refuses with the vendor supplied code to work deftly in landscape. After multiple messages they informed me that their driver does not support rotation for Arduino. So I give this library a try, starting with the rotation example.

I noticed that my board is not among the standard boards. I tried to set up my own board via custom board but it hangs. I must admit I am a bit overwhelmed by all the settings.

What should I set to get rid of this message?

Hi @christophe195,

You can refer to the steps here and set ESP_UTILS_CONF_LOG_LEVEL to ESP_UTILS_LOG_LEVEL_WARNING via esp_utils_conf.h to get rid of this part of the Log information.

[Lzw655]

BTW, simple_rotation currently does not support rotating the MIPI LCD. Moreover, there is currently no example to implement the dynamic rotation of the MIPI LCD (i.e., controlling arbitrary rotation during runtime). If you can accept static rotation (i.e., rotating only once during power-on), please use the example simple_port and set LVGL_PORT_AVOID_TEARING_MODE in lvgl_v8_port.h to 3, and finally set LVGL_PORT_ROTATION_DEGREE to adjust the rotation angle.

@Lzw655

Thanks for your information, the problem is that the screen keeps black. Do i need to set pins somewhere?

Good to know that simple_rotation not works, i only need to change the screen 1 time so te lvgl_port_rotation_degree needs to be good for me.

@christophe195

You can first check if the screen backlight is turned on. If not, you need to check if the relevant pins are normal. If it is turned on but there is no display, please refer to the above answer to set ESP_UTILS_CONF_LOG_LEVEL to ESP_UTILS_LOG_LEVEL_DEBUG, and then send me the complete LOG information. I can help you analyze the problem.

[christophe195]

@Lzw655

Thanks for the backlight check, it was off. After changing the io it is on now but the screen is black (with backlight on now)

this is my console: https://pastebin.com/FzqcKKeU

[christophe195]

i did found some settings in the orignal demo files (that i can not rotate)

now i have a white screen with black lines on it and 2 purple lines with flicker, i think the purple is from the demo file i try to open "lv_demo_widgets()". I need to say that one spot on the screen gets hot (not burning).

settings i found: https://pastebin.com/8QHu5FAZ

It seems that you haven't configured ESP_PANEL_BOARD_LCD_VENDOR_INIT_CMD. Please modify the data here according to the initialization parameters provided by the LCD manufacturer:

ESP32_Display_Panel/esp_panel_board_custom_conf.h

Lines 293 to 305 in 2128a6e

	#define ESP_PANEL_BOARD_LCD_VENDOR_INIT_CMD() \
	{ \
	{0xFF, (uint8_t []){0x77, 0x01, 0x00, 0x00, 0x10}, 5, 0}, \
	{0xC0, (uint8_t []){0x3B, 0x00}, 2, 0}, \
	{0xC1, (uint8_t []){0x0D, 0x02}, 2, 0}, \
	{0x29, (uint8_t []){0x00}, 0, 120}, \

Wow, i have picture now. Thanks. Now only the touch. I have a GSL3680, but ther is no GSL3680 in the list with touch drivers. Can i add them like the custom screen?

[Lzw655]

Great. For GSL3680, we don't have its driver yet. Moreover, the touch can't use a universal driver like the LCD. It needs to use its own communication protocol to parse the data. If you can provide me with a copy of its data manual and a driver example, I can help you configure its driver when I have time.

[christophe195]

Hey,

I must admit that I have already received much more support from you than from web store where I bought the device, thanks!

There is a zip file with all the info of this device but again some things are missing including a datasheet of the touche. Fortunately there is an arduino demo included.

I will add the file with the working example here, is that enough?

http://pan.jczn1688.com/directlink/1/HMI%20display/JC8012P4A1C_I_W_Y.zip

the example is in demo > arduino-examples > esp32p4_lvgl_v8

[AudunKodehode]

Guition customer service is awful. Im on same device and also looking to use landscape, can you please tell me what file you are editing to set the config? I see no occurance of the settings you talk about in lv_conf.

[christophe195]

@AudunKodehode

Sadly yes, it seems a great product but bad service.

• first install this library (download as zip and use arduino IDE to unpack it)
• go to examples, select this library => arduino => gui => simple_port example, multiple files will open. Save the project as another project so you can use the files as baseline.

- i did use the lvgl4 port example of this library and changed the 'esp_panel_board_custom_conf.h' to the code underneath. - I have changed the orientation by changing `#define LVGL_PORT_ROTATION_DEGREE (270) // Valid if using Arduino` in file "lvgl_v8_port.h" on line 95

code: https://pastebin.com/745g3JZS (github is not happy with a .h file)

[AudunKodehode]

@christophe195
Thats awesome!
I copied your esp_panel_board_custom_conf.h to the example, and set
#define LVGL_PORT_ROTATION_DEGREE (270)
and
#define LVGL_PORT_AVOID_TEAR (3)

But stil its in portrait mode 🤔

[christophe195]

@AudunKodehode but you have a picture on the screen? Try to set the LVGL_PORT_ROTATION_DEGREE to 90 or 180. Does that rotate the screen?

@Lzw655 i see the "Help Wanted" badge, how can i help?
