Pi 4 support #149

Closed d1runberg closed 4 years ago

d1runberg commented 4 years ago

Is Tjbot supported using the pi 4? The docs say nothing about it and want to be sure before making recommendations on hardware.

jweisz commented 4 years ago

From a software side, I believe everything should work, but I haven't tested it myself yet.

From a hardware side, we have a community member who altered the design of the 3D print to accommodate the RPi 4. @maryamashoori has more info on the status of this.

Awesome! Do we know if the cardboard laser cut files work, or do they need to be modified in some way?

The 3D print for the Raspberry Pi 4 is almost the same as for the Raspberry Pi 3 B+, except for the jaw. The holes in the jaw for the usb and network ports needs to be mirrored. The tjbot node-red install process almost results in a working tjbot. The only issue I ran into so far is that when the led is enabled in the tjbot node configuration the deployment fails/hangs/loops...

I managed to get the led working on a Raspberry Pi 4. The led does not initialise with the imported node_rpi_ws281x-native module. It does not report any errors, it just hangs when trying to initialising the led control. This issue is also described here.

I managed to resolve the issue for now by replacing the imported rpi_ws281x library (of a specific tree version) in the source folder of node-rpi-ws281x-native by the master branch.

Here are the commands when running node-red:

_# cd ~/.node-red/nodes/node-red-contrib-tjbot/node_modules/rpi-ws281x-native/src # rm -rf rpi_ws281x/ # git clone --recursive https://github.com/beyondscreen/rpi_ws281x.git # cd ~/.node-red/nodes/node-red-contrib-tjbot/nodemodules/rpi-ws281x-native # node-gyp rebuild

So tjbot is now fully operational on a Raspberry Pi 4, at least mine tjbot is.
