You see now, this is why you don’t use or build a Hal it’s easier to just write straight code for the functionality you need

ZacckOsiemo

ZacckOsiemoOP•12/2/24, 7:34 AM

Because we maintain code more times than we write it, we need to optimize for that rather than for well written code

attached to the pi through the USB and HDMI - but it just flickers output. I assume the power draw is not enough got it on the usbc - to usba?

Any tips or tricks to get around this?

don't use you usb port for powering something

segfaultdev.elf

segfaultdev.elf•12/2/24, 9:53 AM

Just use it in case of data transfer

segfaultdev.elf•12/2/24, 9:54 AM

try with external power supply

segfaultdev.elf•12/2/24, 9:56 AM

specially raspberry pi's they can't provide large amount of current

matthewflynn_

M

matthewflynn_•12/2/24, 9:59 AM

Yes I agree - I need to use the usb for touch capabilities though - the unit has 2x usbc outputs though. Can I use one for providing power to it do you think? and one for connecitng to the pi?
