Would this be directly compatible with a Pi 3b or a Pi4? #3

Managed to aquire one D2 on as is returns on official anycubic ebay that seems to be working fine.

I want to use @sn4k3 Klipper-MSLA branch to controll a custom printer with zoom and focus capacity on the DLP side.

Would the current shield work directly on a Pi3B, Pi4 or would i need to make changes to the schematic?

Btw do you have a paypal tip button anywhere? Thanks in advance

I have an additional question, I saw you using software I2C, any special reason to go software instead of hardware I2C?

I think it should work on those Pis, but the thing to check would be if there are any special changes with the respect to the Display Parallel Interface (DPI). Other than that i think the hardware should be fine.

Please do report back if it gives you trouble; we can try to see what must be changed software wise or hardware.

The DPI occupies the hardware i2c pins and they cannot be remapped unfortunately. So software it is 😃
