Clock-Radio-Project

Adafruit Feather M0+TFT+MP3+WiFi Radio+Stereo

In this project, I am using:

Adafruit 3.5" 480x320 TFT FeatherWing https://www.adafruit.com/product/3651 Adafruit Feather M0 WiFi with ATWINC1500 https://www.adafruit.com/product/3010 Adafruit DS3231 RTC FeatherWing https://www.adafruit.com/product/3028 Adafruit Music Maker FeatherWing (no amp version) https://www.adafruit.com/product/3357 Adafruit TPA2016 Amp https://www.adafruit.com/product/1712 SparkFun SI4703 FM Stereo Breakout https://www.sparkfun.com/products/11083

Essentially, my project is a touchscreen clock radio (FM Stereo) with MP3 player and eventually Internet Radio. I am using the TPA2016 amplifier to couple the audio signals from both the SI4703 FM Stereo module and the Music Maker FeatherWing.

HARDWARE MODIFICATIONS MADE:

1. Due to conflicts with Music Maker FeatherWing, on the FeatherWing TFT: DC was jumpered to A1 TCS was jumpered to A2 RCS was jumpered to A3 SCS was jumpered to A4
2. Due to conflicts with the M0 VBATPIN located on A7 (aka "D9"), on the Music Maker FeatherWing: DREQ on D9 was jumpered to D11
3. Jumpered IRQ pin on TFT FeatherWing to A5 to serve as an interrupt (code pending)
4. Wired a voltage divider from USB pin to A0 to detect when USB/power adapter is present (USB--10Kohm--A0--10Kohm--GND)
