White Screen on ILI9341 TFT w/ Audio Shield

[nikhilt0203]

I’m using Teensy 4.1. For the TFT I’m using pins:

15 - DC
14 - CS
13 - SCK
11 - MOSI

The TFT goes blank when the audio shield is connected. Is there a pin conflict here that I’m missing? Any guidance would be appreciated, thanks

The audio adaptor has a capacitor on pin 15 - remove that or pick a different pin for DC.

Thank you! BTW, I used your dynamic library fork for this project, so thanks for that too.

Good to hear I have another customer! I’ll aim to bring all the Teensyduino 1.60 changes in once that’s been released.

Nice project, don’t think you posted that in the blog threads yet? I imagine others will be interested.
