Retropie and waveshare 3.2" (b) screen

[bpennock]

Hello all, I am new to retropie and Linux in general. I thought that a raspberry pi project would be good for me to learn it.

Recently I purchased a wave share 3.2" touch screen that connects directly to the gpio no HDMI or a nothing, it came with a CD containing a burning program that allows the .ISO on the CD to be burned to the SD card.

I have installed the retropie in the SD card and it will not run on the screen only through HDMI. So, I erased retropie and installed the os from the .ISO on the disc that booted directly to the custom os and displayed on the screen.

I am rather new to this all and I know that it is not PnP is there any way to get this all to work? So I can have retropie on my SD card and working on this screen?

Here is the link to the screen

I am using a raspberry pi model 2 B

Thank you

I too have purchased a waveshare monitor in the past, though mine was 7". The DVD should contain a few things, there is/are ISO file(s) that have Raspbian OS all configured to use with that specific screen. There should also be "driver" files, that will override certain config files that will essentially tell the Pi how to talk to the screen, and install the touch support if the monitor is capable of that.

But the way I find best and easiest is to get the Pi all setup on a different HDMI monitor. Then edit the boot/config.txt file yourself

edit these, and you should be good to go (assuming your monitor uses a 320 x 240 resolution at 60hz)

hdmi_force_hotplug=1

hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt=320 240 60 6 0 0 0

max_usb_current=1

Adafruit has better instructions if you are confused:

@obsidianspider made a good screen instruction here

That post was the result of two hours of tinkering. I hope it helps. Those screens are really nice.

@obsidianspider I used your settings today at mine screen. Works like a charm :)
Do you have a instructionset to use GPIO key input?

Moreover also a good instruction set is available here!

@cyperghost You mean this post? I used the Adafruit retrogame software for the GPIO to keyboard stuff. It was easy.
