In other words:
Using the Arduino IDE serial monitor with my Itsy Bitsy, serial communications works perfectly.
Using the program I wrote in C#, the Itsy Bitsy doesn't receive bytes.
However
Using the Arduino IDE serial monitor OR using the program I wrote in C#, the Arduino running the same code as I tried on the Itsy Bitsy, works perfectly.
I've tried multiple Itsy Bitsys, and both the 3v and 5v versions. Always the same results. I see two possibilities:
1. The USB converter that is used for Itsy Bitsy (but not Arduino) doesn't play nice with C# for some reason,
2. I'm not as smart as I thought I was...
I'm including both the Itsy Bitsy / Arduino code.
I'm also including the C# program for reference.
Code: Select all
