CCS10 Syscfg for final pinout
https://github.com/davidzwa/advanced-iot-lisat/blob/master/src/MSP432LISAT/MSP432P401R_LISAT_ccs/MSP432_LISAT2_new.syscfg

Written out
This is more to make sure we dont exceed the pins and avoid assigning too many to the MSP432. The ESP8266 can also do some tasks if needed.

External

• Speaker (PLAY/STOP, has own battery, runs on ~4.7V) = 2 GPIO (or 3)
• Mic x3 (WOS/DOUT/VOUT) = 2+2 GPIO in/out, 2 ANALOG-IN GPIO
• ESP RX/TX = 2 UART GPIO
• LED x4 (check if MSP432 output can drive LED's)

Internal/chassis board

• Tacho x2 (pulse direction and speed signal) = 2 GPIO + 2 GPIO (timer capture)
• Motor x2 (DIR, SLEEP, POWER) = 4 GPIO, 2 PWM
• Line sense x8 (11 pins, OUTx8, 3V3, GND) = 8 GPIO INPUT + 1 LED GPIO OUTPUT

Total required:
External: 2+6+2=10
Chassis: 2+6+9=17
Total: 27 pins
Available: a lot more

@tomasvr we need the pinout from Syscfg as well to match up with the peripheral specs above.
