Hello,

About 4 of the touch capacitive pins on my Teensy 3.2 board stay high, around 65000. I’m using the touchRead function.
I used some pins to solder the teensy to a teensy audio board.
Is the problem most likely my poor soldering? There doesn’t seem o be any solder which connects the bad pins.
The rest of the pins work as expected.

Any other troubleshooting steps for this?

Thanks,

Craig
 
Hi, which pins are you using? I'm seeing the same behavior when trying to use touchRead() on A8 and A9 when also connected to the audio shield. I'm also running 50 neopixels from pin 20.

I'm going to try moving to other touch-capable pins that aren't as close to my neopixel line. I'll report back if this improves things.

The audio shield uses those 2 pins for LRCLK and TX.

D'oh! I've moved the touch pins to 16 and 17 and they're working as expected now.
Thanks Paul!
