BQ28Z610EVM-532: Communication problem with ardiuno

Part Number: BQ28Z610EVM-532
Other Parts Discussed in Thread: BQ28Z610, BQSTUDIO, EV2400

Hello,

I am trying to use a BQ28Z610 EVM with an arduino, but I have a communication problem between the two devices.

I just need to tell the battery manager the batterie properties and to programm the charge. I don't need more, this is just a for a first prototype. I read the technical reference manual (which is quite clear) but I am not able to start a communication between the arduino and the BQ28Z610.

I tried to install the firmware with BQstudio, but it doesn't worked. The device is not reconized by the computer. Do I need to first use a USB/I2C converter? Is it possible to use something else than the EV2300? I read that the BQ28Z610 needs to be configured before using it with arduino. If I can use BQstudio and arduino, is it necessary to use something like the Firmata library? Is it the same if I use an Arduino library without BQ studio (there is no library for this one but for other BMS, it could work with some changes)?

Thank you,

Yohann

  • Hello Yohann,

    You will need an EV2400 with bqStudio to program the firmware on bq28z610. It is possible to use a MCU to directly communicate with bq28z610 but you will need to figure out every small detail and IMO it is not worth the effort.
