Redboard Artemis - Midi Shield - Help

Development Boards Artemis
1

Hello,

i’m new to this community. I just got my Redboard Artemis and Midi Shield by mail and soldered it according to the hook up guide.

I try to make a simple function test of the midi shield, but somehow i cannot read the A1 pin.

analogRead(A0); // reads different values when i turn the encoder

analogRead(A1); // does read always zero when i turn it

I measured the voltages with my volt meter on the Redboard Artemis: A0-GND and A1-GND and both seem to work fine and independantly.

Is there any kind of setup for the pinmodes or something that i missed?

I noticed, when i turn any of the both encoders to the max position, the TX and ON LED on the Artemis Board get a little brighter, which looks wierd.

(Win 10, Arduino IDE 1.8.16, Apollo3 Boards 2.2.0 → “RedBoard Artemis”, “SparkFun Variable Loader”, Only connection is USB-C)

Thanks for helping :wink:

I just found out that the analog inputs A0-A5 only work on the board version 1.2.1-1.2.3.

From 2.0.5 to 2.2.0 only A0 is working. Why is that?
