I was just wondering if a wiring diagram would be possible for a Raspberry Pico RP2040 and this screen ( http://www.hiletgo.com/ProductDetail/2157359.html )?

That display would not work because it uses an I2C interface. You would want one with a SPI interface. Here are some options:

(Seems narrow, but could work) - http://www.hiletgo.com/ProductDetail/2157364.html

This one will work if you can source it (beskar) - https://www.waveshare.com/product/displays/lcd-oled/lcd-oled-3/1.3inch-lcd-module.htm

This one will also work (pre-beskar) - https://www.waveshare.com/product/displays/lcd-oled/lcd-oled-3/1.14inch-lcd-module.htm

Thank you so much Breazile! I was able to get the Waveshare 1.3in LCD display you linked for the beskar version. Would you happen to have a wiring diagram for that screen?

[Breazile]

Same as the Beskar LCD wiring on my page here: https://github.com/Breazile/MandoPuter

Signals are the same, and here is how you map the names compared to the Adafruit LCD

VCC = VIN GND = GND DIN = SI CLK = SCK CS = TCS DC = D/C RST = RST BL = Lite

Thanks again, you're the best!

I was able to get it working, thanks again! One more question regarding the Mandoputer, on this display it has the same ports on the top and bottom. I used the included wiring harness that connects to the bottom, but the top row make it just a little too tall to fit properly into the Great Ape bracer. Is it possible to cut off the top row of ports?

[Breazile]

Glad it worked.

I have not tried it, but it does not look like it would affect it. I would be careful not to cut too close to the flex cable.

[Gstricklin86]

Ok, I'll give it a shot and see how it goes. I can always just get a new screen if it's not successful. I appreciate the help. You haven't, by chance, started any work on a Whistling Bird project, have you? That's my next project.

[Breazile]

I started it, but then had other things going on. I have the Amban rifle to finish, and I'll probably revisit the birds this Fall when I work on my Mando setup some more.

Good luck with the display.

I figured out parts of it, but couldn't get it to work together like I wanted. Display worked like a charm! I carefully cut the top off with a dremel, (thankfully the board is already separated along the ribbon cable) I powered it up, and it's perfect.

Thanks again for all your help!
