I recently received a EVE4 7" display:
https://www.matrixorbital.com/ftdi-eve/ ... 4x-70g-ips
I have previously worked with an EVE3 5" display connected to an ESP32 micro-controller. The 5" was working well but when I tried to replicate the connections and code (with parameters changed) on the EVE4 7", I am not getting a working display.
I have included the image of what I am getting on the display in hopes of someone possibly recognizing what is going on or can point me in the right direction. I have tried the example code from Matrix Orbital and also Rudolph's code and I am not having success with either, just the white horizontal lines. The lines are not static but jump around the display.
Raquel was assisting me and shared the updated parameters for the EVE4-70G which I am using:
DWIDTH = 1024;
DHEIGHT = 600;
PIXVOFFSET = 0;
PIXHOFFSET = 0;
HCYCLE = 1259;
HOFFSET = 85;
HSYNC0 = 37;
HSYNC1 = 40;
VCYCLE = 768;
VOFFSET = 16;
VSYNC0 = 13;
VSYNC1 = 20;
PCLK = 1;
SWIZZLE = 0;
PCLK_POL = 0;
HSIZE = 1024;
VSIZE = 600;
CSPREAD = 0;
DITHER = 1;
I do not have a USB2SPI connector to try as I didn't think it was necessary based on my previous success with the EVE3. Any help or suggestions would be greatly appreciated!

Re: EVE4 Assistance
I'm not sure what the issue was before but the display is now working fine with the above parameters.
