/* This is a project for madelectronengineering.com
 This code is used for a hardware monitoring system for the Hybrid Supercapacitor Car Battery to monitor the supercap voltage, the LiFeP04 voltage,
current, and wattage, plus also monitor 3 seperate temperature points.

Required hardware:
    STM32 NUCLEO-L073RZ
    TMP36 Temperature Sensors (x3)
    INA219 Current & Voltage Breakout (modify by removing 0.1Ohm resistor and replacing with 0.01Ohm Resistor to measure up to 32Amps
    ST NUCLEO Protoboard
    30k & 7.5k resistors for voltage divider to measure supercap voltage
    0.1Ohm 25W current limiting power resistor in between supercap array and LiFeP04 battery
    Sharp Memory LCD 400x240
    
The INA219 measures the current and amperage on the battery side of the current limiting resistor to keep an eye on the LiFeP04 battery.
voltage divider connects directly to + of supercap array

Arduino equivelant connections:
A0 - TMP36 #1
A1 - TMP36 #2
A2 - TMP36 #3
A3 - Voltage divider Input
A4&A5 - I2C for INA219

Arduino equivelant connections for LCD Screen:
D13 - SClk
D11 - MOSI
D10 - CD
D9 - Enable
D8 - Extcom
