WaveShare 10.3inch e-Paper HAT Issue

[lbrent2k]

Nothing displays - see output provided below.

Per WaveShare Wiki VCOM should be: epd -1.50 1 though my display indicates 1.46, both work.

Can I modify configuration to point to: /home/lbrent/bcm2835-1.60/IT8951 which I installed from WaveShare? When I run demo from WaveShare, the display works.

Hi there and welcome to Inkycal. Thanks for opening this issue. As this is your first issue in this repository, please read through the contributing guidelines

Hi there @lbrent2k and thanks for reporting this issue.
Inkycal was able to interface with the display, proving the correct wiring and driver selection. As the waveshare demo also works with the same setup, there's a high chance the issue is related to the settings.json file.

More particularly, the weather module doesn't like much height as it will attempt to stretch the height to the given height, resulting in some distortions. Please try this again with the jokes module or use several modules and adapt at least the height of the weather module to around 20.

The new settings.json file should override the current one and the Raspberry Pi needs to restart after this, which will hopefully fix the issue.

Please let me know if that worked

I modified the module to jokes. Still, no screen refresh, no screen output.

I just realised there are now two different versions of the 10.3" e-paper hat. Which one did you buy, the normal one or the 10.3inch e-Paper HAT (D) one?

[lbrent2k]

I am using this: https://www.waveshare.com/10.3inch-e-paper-hat.htm It includes the driver board.

[lbrent2k]

I think this should be changed to Bug instead of Question since I have verified that display works when running the WaveShare demo and it appears that inkycal has been installed and configured properly, yet the display remains unresponsive

[aceisace]

May I kindly ask you which commands you had to run to test the waveshare code? At the moment, I am not sure what is different from the waveshare-version.

[lbrent2k]

I am following directions from: https://www.waveshare.com/wiki/10.3inch_e-Paper_HAT to succesfully run the WaveShare Demo:

cd bcm2835-1.60
./configure
make
sudo make check
sudo make install
sudo apt install gpiod libgpiod-dev
cd IT8951/
sudo make clean
sudo make -j4
sudo ./epd -1.50 1
