Firmware development for Power-Battery circuit control using ATmega328 (Arduino)

Basic hardware design is done using ATmega328 and other chipsets. I need someone to develop the firmware code for ATmega328 and test it to control the power and battery management subsystem. Most of the key functions will be handled by commercial chipsets used in the design. ATmega MCU will turn on/off the power and control the chipset and communicate to/from Raspberry Pi through SPI and GPIO.

Required skills:

- Previous battery / power management experiences

- Ability to read and understand the hardware schematics

- Ability to understand the details in the datasheets

- ATmega328 firmware development and debugging

Deliverables:

- Development of firmware for the functions listed below

- Test and debugging

- Firmware version management, uploading from RPi

- All source-codes and test programs

- Brief documentation

Functions:

1) Power on/off/reset

- Power On: ATmega sense the power button press (>200msec)during the power off state -> Turn on the power

- Power Off: ATmega sense the power button press (>200msec) during the power on state -> Send shutdown signal to RPi through GPIO (POWER_DOWN) -> RPi shutdown start -> Query RPi Still_Live? -> If no answer, power off after (1?) second

- Reset: power button pressed for 5 seconds

2) Battery Management

- Status display with 2-color LED (Red-Charging, Green-Fully charged)

- Low battery warning: When the battery remaining level is under the predetermined level (set by RPi), send warning signal to RPi

- Auto-Shutdown: When the battery voltage is under the critical level (set by RPi), send warning signal to RPi (RPi display warning to connect the adapter) -> if not connected to adapter for 1 minute, start the shutdown process

3) Firmware load/update

- Support firmware update from RPi

- FW version check

4) Battery save in standby-mode

- Minimize the power consumption during power off and standby mode
