I found this thread, which is quite old and suggests making a new thread, so I did:
http://www.brtcommunity.com/index.php?topic=220.0
There also weren't any definitive answers in that thread, and I amhoping that has changed since it was posted.
I have previously used a FT810 with a natively RGB panel, and am now looking at using a FT811 (48pin) with this panel that has a ST7789V controller on it: https://www.buydisplay.com/2-4-inch-ips-240x320-tft-lcd-display-capacitive-touch-screen
I think I have the connections correct, and am looking for confirmation:
Panel FT811
VSYNC VSYNC
HSYNC HSYNC
DOTCLK PCLK
DE DE
DB17:0 R7:2|G7:2|B7:2
RESET DISP
The RD, WRX, D/CX, CSX, and TE pins from the panel are all unused
As the other thread asks, it also appears that the ST7789V needs to be configured via SPI before it will work in RGB mode, but then after that, SPI communications to the display are no longer needed, is that correct?
My current design already has several devices on the SPI bus and can't natively support another CS, but if the ST7789V only requires a few SPI instructions for initialization, I can can easily MUX the FT811 CS and use an MCU GPIO to control whether SPI traffic selects the ST7789V or the FT811.
Thanks
