Hi Where can i find a data sheet / pin configuration for the Display-O-Tron 3000? Could one change a gpio-pin (when its already in use) ?

I think it uses i2c apart from the joystick, you can work out which pins the joystick uses from here; https://github.com/pimoroni/dot3k/blob/master/python/library/dot3k/joystick.py @gadgetoid or someone may be able to help you with the chance of changing the configuration. Gordon

Thanks, beside the joystick what pins are used for lcd itself?

Not sure what you mean by changing a pin when it’s already in use?

I will rephrase. I am already using some gpio pins on the raspberry pi board. In order to connect the display-o-tron 3000 i have to connect it myself using wires and I assume not all 26 pins are used for the dot3k. this is why i would like to see a data sheet, so I can see what pins have to be conn…

At the moment we don’t have datasheets for our add-on boards since we expect most people will just plonk them right on the Pi, but as Gordon suggests it’s really simple to dig into the library and find which pins are used for what. Some pins you can re-assign reasonably easily ( the Joystick, and t…

I have the exact same need as @terriblez here. My project (mentionned in other post) is to plug RPI with HifiBerry Amp+ and Dot3K Hat. I’m trying to figure out which PINS are need for both AMP+ and DOT3K because I will obviously not be able to plug directly these two “hats”, i will need to break out…

I’ve made a lot of test and finally found the answer. I’m sharing! [image]

Nice work! Incidentally I’m actually in the middle of a very drawn out project ( I have so much other stuff to do it gets very little attention! ) to update Pinout with board compatibility functionality so it can produce visualizations similar to yours. I’m guessing HIFIBerry uses the I2C pins ( th…

Yes i forgot to put the caption for the RED Pins. Yes it does work together. You need to connect GPIO 3 and 5 to both HifiBerry Amp+ and Dot3K and it does work together. I plugged these via a breadboard to test it. This was a mess but it worked :-) [image] [image] [image] [image]

Have a look here; Dot3k Pins looks like it’s I2C and SPI plus the GPIO for the joystick.
