Factory test program for the primary battery shield, originally designed for the C030 board and carrying a BQ35100 battery monitoring chip

Battery Shield Factory Test

This is the mbed test program for the C030 primary battery shield. It instantiates a BQ35100 battery gauge and lights the LED on the C030 board as follows:

• Flashing amber: running but no conclusion yet.
• Flashing green: pass (BQ35100 is there and battery is at or above the threshold of 2.8 Volts)
• Flashing red: fail (not able to enable gauging on BQ35100 or battery is below threshold)
• Solid red: failed to even start.

Progress may also be monitored with a serial terminal running at 9600 baud.

To build this program, import it into your mbed environment, set the target to any UBLOX_C030 target and the toolchain to your favourite toolchain (e.g. GCC_ARM) and compile it. Then drag and drop the binary onto the C030 board to which the primary battery shield is attached.

The program is not actually specific to UBLOX_C030 boards, any mbed board with an I2C interface and a three-colour LED may be used (obviously you will need to change main.cpp so that the LED1, LED2, LED3, I2C_SDA and I2C_SCL pins are correct for that board).

A pre-built binary that may be used on a UBLOX_C030_U201 board is also included.

NOTE: this program has it's own version of the BQ35100 driver rather than linking to the library since it will be used on production parts which have been sealed and hence the reading of the seal codes that is usually done in the init() call to the driver (so that the device can be configured through API calls) has to be hacked out.
