Can't find lut time definitions. #5

Closed TG-Techie closed 5 years ago

TG-Techie commented 5 years ago

i know the display is advertised for partial refresh but i though i would give it a try. i'm looking through the code and i cant find where the timing for the page changing is. i tried chafing the lut_bb,wb,bw2,ww etc in .py and allot of other parameters i just can;t find any comments that say where the time in-between number of inverse flashes what refreshing display is. i checked both files and oi just don't see it in comments or code.

thanks for any and all help, TG-Techie

some displays have the LUT built into the display, which is good becuase the LUT should be customized per manufacturing run. Some displays have it as a bytearray - check the SSD chips to see a LUT-loading example. compare to the arduino code :) https://github.com/adafruit/Adafruit_EPD
