`'ST7262_PANEL_IO_3WIRE_SPI_CONFIG' was not declared in this scope` using a ST7262 RGB screen

[lboue]

Hello,

I have a ST7262 LCD screen and I am trying to build an example but I am facing another error: 'ST7262_PANEL_IO_3WIRE_SPI_CONFIG' was not declared in this scope I don't understand why I'm getting this error with regarding a 3 wire SPI bus when I'm using an RGB screen.

Did I miss something?

Hi @lboue, please set the macro ESP_PANEL_LCD_BUS_SKIP_INIT_HOST to 1 if you are not using 3-wire spi.

ESP_PANEL_LCD_BUS_SKIP_INIT_HOST

@Lzw655 Thank you for your time. Build is OK now. Where can I find this information that you don't have to initialise it for an RGB screen? I haven't seen it.

[Lzw655]

Sorry, it's a missing information. And I added it in the new PR. Please take a look. Thank you!

[lboue]

It's perfect. Thanks for the quick response!

[Lzw655]

You're welcome. Thank you for your contribution!
