Hi All,Are there any TouchGFX examples driving multiple displays over SPI using ILI9341 controller? I am able to drive a single 320x240 display no problem but run into issues when extending to two displays.I'm guessing I am sending too much data over...

Thanks again for your continued support. Any suggestions on how to improve upon waiting for two callbacks?I have optimized the ILI9341_SetWindow and ILI9341_DrawBitmap to combine SPI1 and SPI2 with little improvement.Is there another LCD controller y...

The mirroring is just for testing. I needed something simple to test driving two displays. You are correct. Eventually I will have independent data going to both displays. The plan is to extend the H.Thanks for the suggestion. I will try reordering t...

Thanks for the reply... Here is what I do... I override the two functions below...void touchgfxDisplayDriverTransmitBlock(uint8_t* pixels, uint16_t x, uint16_t y, uint16_t w, uint16_t h) { isTransmittingData = 1; ILI9341_SetWindow(x, y, x+w-1,...

bits per secondThe code works fine with one LCD. I can even drive the LCD faster... I can set the SPI to 25mbps and the display appears to work fine...The 2 LCD application takes the same pixel buffer and send to both screens inside the touchgfxDispl...

So I tried changing the blocks from 3 to 6 to 9 but it did not appear to improve performance. The code still appears to crash when I try to drive the SPI > 6mbps. I have seen videos where the displays are being driven way faster. Any other thoughts o...
