Adafruit Audio FX Sound Board + 2x2W Amp UART issues

Post by Buzkhashi »

I can trigger sounds on my AdaFruit Audio FX in GPIO mode, but cant seem to get anything going at in in UART.

I am using a Parallax Propeller Mini https://www.parallax.com/product/propellermini/ and think I have my serial protocol set up properly.

I just read about the RX/TX possible swap issue. I will check that in the morning, but have tried swapping lines previously without success.
I'm curious if there are any issues commonly seen with the setup when using Parallax products?

Hi Buzkhashi, I don't know about using a Sound Board with a non-Arduino microcontroller. But the "Serial Audio Control" page of the guide says it's possible "with a little adaptation". Have you made sure the UG pin of the Sound Board is grounded? As you alluded to, you also want the TX of the Sound Board connected to the RX of the Parallax, and the RX of the Sound Board connected to the TX of the Parallax.

The "little adaptation" they talk about probably relates to making changes to the library so it works for your particular microcontroller, then including the modified library in your code.
