Unable to draw rectangle about ft81x_arduino_driver HOT 4 CLOSED

Hey @bcorwen, very cool that you built your own! 😃

I'm sorry to hear that you ran into issues, though. To me there's no known problem with drawing rectangles. I'm not sure what's happening here. If you just replace the drawCircle call with that drawRect call I'd expect it to work properly.

I also think it's pretty unlikely that it's an issue with the chip or the hardware in general since other examples seem to work just fine... 🤔

I've found the problem after a little trial and error. Sharing in case it helps others.

In my example, I was using the following parameters:
ft81x.drawRect(20,20,4,4,0,FT81x_COLOR_RGB(255, 0, 0));
I assumed corner size should be 0 for a perfect rectangle with sharp corners.

However I should be using a value of 1, as this draws rectangles successfully without any soft corners.

Simple mistake to make. I'm just glad it's all working!

Thanks again for your library and board design!
