### Hardware: Observations

The Huzzah32 uses its SPI bus to communicate with the touch sensor and the

TFT screen. It's `MOSI`, `MISO` and `SCLK` pins are shared with the other

devices, and it selects which slave device to communicate with by means of

#### Soldering Requirements

The `LITE` and `IRQ` pads on the TFT Featherwing have to be soldered to
