Screen turns white after some seconds

Hi

I have a FT800 module from haoyu (hy50b) and when trying your patches after a few screen resets the screen turns white. Any idea why this could happen?

Tried several things but no success. (internal clock, lower spi frequency...)

Question relating to:

Lib for FTDI FT800 graphic controller "EVE" The API is changed from the FTDI original names. It use smaller names now. DL() will add something to the display list instead … eve, FT800, graphic, LCD, TFT, touch

The parameter for the tft are in FT_LCD_Type.h . Please check with the datasheet of your module. Are you see something before the screen get white ?

Yes, I can see the first screen showing up perfectly. And sometimes I get to see the sliders of your demo, but after that it flashes white. The TFT parameters seems right (a arduino lib that uses this screen uses the same values).

This is the datasheet, but can't find the values I need in it: http://www.haoyuelectronics.com/Attachment/HY5-LCD/LCD%20Datasheet.pdf

EDIT: I think I found the problem! One of the wires was broken. Still having errors with the calibration, the old touch example works fine though.

BTW: any reason why u use ft_uint8_t instead of uint8_t? Just wondering
