Colors are incorrect when using supported board

[jompjomp]

I’m using BOARD_JINGCAI_JC8048W550C, but the colors are incorrect when using LVGL 8. It’s interesting that all the colors are represented, just not all in the correct locations! It seems like red and blue are swapped? Using 16 bit mode on Arduino.

Using this: https://www.imagepypelines.org/examples/imaging/swap_red_and_blue.html

And sure enough, reds and blues are switched.

Pinging lsroka76 since you have the panel/contributed the board file. Does this behavior happen on your end as well?

Hi @jompjomp,

It seems that the RGB pin order in the board configuration file is reversed. I will fix this issue as soon as possible. Thank you for your feedback!

This board also has the same issue that BOARD_JINGCAI_ESP32_4848S040C_I_Y_3 had:

Issue: #188

As with that board, this code fixed it:

#if ESP_PANEL_BOARD_BACKLIGHT_TYPE == ESP_PANEL_BACKLIGHT_TYPE_PWM_LEDC
    /**
     * @brief PWM parameters configuration
     */
    #define ESP_PANEL_BOARD_BACKLIGHT_PWM_FREQ_HZ   (1000)  // LEDC timer frequency.
                                                            // Different backlight driver chips may have different
                                                            // frequency limits, please refer to the datasheet of
                                                            // the specific chip.

                                                                // The frequency and duty resolution of the LEDC timer
                                                                // need to be properly matched, please refer to:

Thank you for pointing out this issue! I will fix them together.

Both issues have been fixed, thank you!
