ST7735 Incorrect color order BGR/RGB #83

Closed thumptech closed 2 years ago

thumptech commented 2 years ago

Describe the bug The colors are incorrect when using the DisplayST7735_128x128x16_SPI, probably all ST7735 drivers

To Reproduce I just used the driver on this module

Expected behavior The correct colors should be displayed

Please complete the following information:

Additional context Changing line 174 of lcd_st7735.inl to: 0x36, 0x01, 0b00001000, // MADCTL sets the correct bit order and fixes the problem for me by telling the controller to use RGB and not BGR

If this is specific to the board I have it would be nice to have a function in the driver to set the pixel format.

Please, find the fix in the latest commit 2de202c5123b8d18dee90674e21ffccb3a5552e7. Let me know the test results

    display.getInterface().setRgbMode(1); // or 0

I've tested the setRgbMode() function and it is working as expected. Thankyou.

You're welcome. Once enough new features to publish are ready, the new version of the library will be released for the Arduino Library Manager.

Thankyou. I just checkout the repo into my ESP-IDF project so it works fine right now. There are other problems with this display, but ill come back to that and create a new issue once ive investigated it.
