@TomKatt RESOLVED - someone pointed out that the example code I was running included a line to wait for the serial port to be enabled. Code always does what you tell it, not what you mean lol.

@TomKatt BTW, I love your Blown Away by Maxell. The ‘Canvas’ is M5’s name for TFT_eSPI ! Keep up the good work!

Public Profiles: Visible to all users, allowing others to see your projects, contributions, and activity. Great for networking and showcasing work. Private Profiles: Restricted visibility, keeping your projects and activity hidden unless shared directly. Ideal for personal or confidential work.

@ajb2k3 LOL - Silly that I never thought to check out the forums at Arduino proper... Most questions are probably generally related to generic ESP32 discussions, but there also seems to be a fair number of M5Stack users as well ;-) Perhaps I'll see some of you folks there...

@TomKatt Cheers!

@TomKatt check M5Stack github

Couldn't decide, so I bought both lol. Each seems to have some different strengths - the Fire has more ports, the cool magnetic base and physical buttons that often work better than touchscreens. As such it's great for tinkering. But the Core 2 seems a bit more 'polished' for portable applications.
