Hello,
I overwrote the sim28 firmware and corrupted the data. Is there an updated or a legacy firmware I can use that you know about right now? I see sim.com is no longer available for searching for firmware.
Seth
P.S. I thought I overwrote the data for some reason. I think you guys set up the device so it cannot be corrupted. Nice! Sorry for this advance.
Hello,
I created an issue on Github.com about the Grove Starter Kit and the OLED Display. Are people still using this OLED Display to create graphics.
I am connected via my i2c bus on the Grove Connector on my BBGW. I have been unable to make it work thus far.
I am using smbus2 right now that I installed w/ pip3 on my Debian Distro.
Seth
P.S. Here is the source I am trying to use:

So, you can see what changes I have made. Trust me, these are not my initial changes but I have tested the source with many of the functions from smbus2 and I just have not got it quite right yet.
If anyone else is working on this project, I would like to hear from you.
