Some questions and one issue

[araeubig]

First i have to say: Your idea and solution is absolutely great and since 1 hour the Waveshare Display is running fine (based on your great installation help / documentation). Thanks for that.

One issue: By shutting down the RasPi the display stays alive. How could i power off the display when shutting down the raspberry?

Some questions:

• i read in the config files that it would be possible to use the display in landscape format. Do you have some hints for me to get this working?
• my goal is to use the same display with touch option (the Waveshare model too) and let the display go off after some minutes and to reactivate by touching it. Therefore it would be nice to get some hints too. At the end the touch should activate the display first and with a second touch i want to display a small menu (HOME (like it is actual the stats screen, HOME2 (with other stats data from influx), SHUTDOWN and REBOOT
• trying to change the backlight to 50% or 25% does not work - it is based on the "workaround pin 17 on Raspberry 5"?

The whole setup should be placed in a DIN/REG case and based on your STEP-files i will make a new "front-cover" for the Waveshare DIN case.

I think i could make a fork of your repo and add the new created files or i could send you all files for your repo if they are ready.

Hello André,

I'm really glad to hear that my project has been helpful and that your Waveshare Display is running smoothly with the installation guide.

Regarding your questions:

1. Shutting down the display on Raspberry Pi shutdown: I might consider adding functionality to detect when the program is closing and, in such a case, clear the screen before the Raspberry Pi powers down. This would ensure the display does not retain any content unnecessarily.

2. Landscape orientation: Unfortunately, this cannot be easily configured through a standard config file. It requires modifying the source code to adjust for the orientation. The good news is that it’s absolutely doable and not overly complicated if you’re familiar with basic coding.

3. Forking the repository: Feel free to fork my repository! It’s under a very open license, so you’re welcome to modify the code as needed. If you want, you can share your updates or improvements as a pull request, but it’s entirely up to you.

4. PWM for brightness control: PWM (used for controlling the brightness) is a tricky topic on the Raspberry Pi 5. That’s why, in my implementation, the brightness is fixed at 100%. If someone manages to come up with a reliable solution for this, I’d be more than happy to incorporate it into the repository.

Best regards,
Robert

I've added some code, and now the program detects when the application is shutting down. Before closing, it clears the screen and cleans up SPI interface.

I hope this is what you were looking for! 😊
