Hi, can someone help with with this problem, I am a newbie so it might be something very simple.
When I run the example from waveshare like so, sudo ./IT8951 0 0 01.bmp
I get the following data:
Panel(W,H) = (1872,1404)
Image Buffer Address == 119F00
FW Version = SWv_0.1.
LUT Version = M841_TFA5210
VCOM = -2.27V
IT8951_GUI_Example
I can then freely put other bitmaps, and test will execute and the images will display.
However, when I try to use the python example, nothing gets displayed. What is worse -- if I come back to the C code, and run the same command, I get blanks:
Panel(W,H) = (0,0)
Image Buffer Address == 0
FW Version =
LUT Version =
VCOM = -0.00V
IT8951_GUI_Example
Since there is no test code for 10.3" display, I am using a randomly picked epd7in5b_V3
and modified the width
and height
. I see that the other displays using this hat are 6", 7.8", 9" but none of those are available with working code examples in this python folder.
There must be a pin that needs to be switched in order to get this going again, but I have no clue where to dig and what to try. I attempted to use the EPD Hardware reset function, but it didn't work
Any help is appreciated!
