EV2400: DIY Interface Device

Part Number: EV2400
Other Parts Discussed in Thread: BQ25703A, MSP430F5529, , BQ27510

Hi all,

I am experimenting with the BQ25703A I2C multichemistry Charge Controller using the relevant EVM. I initially thought I could get an EV2300 which is around $99, unfortunately, it turns out the EV2400 is double that. More exploration later I discovered that the EV2400 uses an MSP430F5529 which I incidentally have a launchpad for. 

Now being a DIY person, I was hoping to hack together a makeshift interface device using the launchpad and for that, I require...

a) Firmware already and baked - I have searched for this, however, it does not exist

b) Protocol information for the USB host communications so that I may write only the I2C comms part. I have a library for the BQ27510, however, do not know how the Battery Studio talks to the hardware.

c) Alternatives and suggestions. I am already using a BusPirate to talk to the board however it would be far easier to have Battery Studio Talk to the EVM.

Thanks in advance.
