I have now successfully printed the case in ASA which has better strength and UV resistance than ABS and is used in industry to print car parts. It is VERY difficult to get a good print and it has taken quite a few attempts. Overheating has been a problem but the current ventilation slots and a fan are sufficient to keep the CPU temperature at around 67.2 degrees C. Thats hotter than i would like but it holds steady. As the case takes a week to print on my Ender S1 Plus I will use it on the boat over the summer while designing a new case with a metal heatsink and fan incorporated into it.
So now I am back to trying to solve the screen dimming software issues.
Hi Frazer, Could you possibly give me some pointers with the code for dimming with PIGPIO? I have tried incorporating what I thought would work into my screen dimmer slider and it doesn't Cheers and thanks H.

I googled "Digiwave HA-101ZIEBCAD1-V 10.1" and couldn't find it. Where did you buy it?

Hi Jodel you can find it here https://www.soselectronic.com/en/product...1-v-378585
Hi Hillzzz,
Did you ever find an answer to the dimmer issue? I've just ordered the screen and would love to set up external dimmer control.
Thanks,
Fraser
Hi Fraser, If it's an external dimmer you want like a potentiometer knob style dimmer then all you need is a simple circuit that goes from zero to 3 volts with a potentiometer to control the voltage. If you look at the PDF circuit specs you will see the connector which controls brightness. I want to do it in software and i haven't found a solution yet. Cheers, H.
Hi Hillzzz,
I was looking at software control too. I came across two issues - the one that you mentioned with the brightness going to zero after quitting the app, and another where there was terrible flicker at lower brightness levels. I resolved the flicker issue using PIGPIO, as it uses hardware PWM timing. It should also resolve your issue as there is a daemon that runs, so the setting should stay on until the power is off. I've implemented a service to listen for the GUI app and change the PWM duty cycle. I've just got a very basic Python tkinter slider to change the brightness. The service starts on boot using systemd.
I'm essentially building a self-contained plotter for use in the open cockpit, so far this screen is looking great.
Thanks,
Fraser
