i was messing around with @robey 's OLED firmware from within Squeak. I’ve been able to create a pixel editor that will “live draw” a bitmap to the OLED display.
It’s still a little buggy, of course, but I’ve gone ahead and pushed some of the code to a repo on the mnt source server.
If you would like to try it out for yourself, follow these steps:
- Follow the instructions to flash @robey’s firmware, which you can find in this post
- Grab a copy of an aarch64/arm64 version of the opensmalltalk-vm from their releases page here.
- Grab copies of the Squeak 5.0 image, sources, and changes files here.
- To run the fresh Squeak image, execute a command that should look something like:
- When running the setup for the first time, be sure to add the Git / Squot tools at the end of the setup
- Once the setup is finished, go to Tools > Git Browser. Right click in the upper left pane and clone my repo, whose address you can find here (be sure to have
.giton the end — a Squot particuarity)
- Once you’ve cloned it, in the lower right pane you can left click the most recent commit and load all of the packages
- Right click on the desktop and select Workspace
- In the workspace, type
MNTOLEDController new openPixelEditor. Highlight this text, right click, and select “do it”. It will take a second to load the first time.
If it all works well, you should be presented with a Squeak window that looks like this:
Simply hold the left mouse button and drag it around the window to activate pixels. You should see the OLED live update and match the drawing as you go:
That’s all for now. Let me know if you have any questions/issues!
PS - For you Smalltalkers out there: the Baseline is not currently working because evidently Metacello doesn’t have support for Gitlab yet. I have a thread going on the mailing list about it.
