Hi, following are my currently enviroments:
- Embedded Wizard Studio Pro v8.30
- Embedded Wizard Platform Package for RGB565
- Replaced a touchscreen with an LVDS input (MIPI-DSI output is covert into LVDS signals by sn65dsi83 chip)
My situation is the replaced LCD only supports DE-only mode (no VSYNC and HSYNC), So I have to change the BspConfigDisplay() function into DSI video mode.
After the my custom EmWi gui screen show up, I found the framerate is really slow. In 'GraphicsAccelerator' example, the framerate is fixed at 0 fps. I have tried to build a project without EmWi GUI, and the fps is more than 40 when using ST VideoMode_DoubleBuffering example. Therefore, I think the configuration might be something wrong in EmWi display settings. But currently I have no ideas, hope someone can give me a hand !!
In addition, I don't understand why HSYNC, HBP, VBP, VFP, ... all of these are set to 1 in ew_bsp_display?
