Other Parts Discussed in Thread: EV2400, BQSTUDIO
Just realised the image I posted shows the cable connected to SMBus... I posted the wrong image, the correct one should show it connected to I2C.
Hi
I'm hitting a problem when I try to open the evaluation software. It throws up an error message which reads 'Unable to read ADC Gain and Offset from connected device. Please ensure a powered bq789X0 is connected to the I2C communications lines on the communication adapter...etc, etc'.
What is particularly frustrating is that I have had this working cleanly in the past - I have just resurrected this project and have now hit this problem so it's quite likely it's caused by something I've got configured wrong.
I'm powering the board using an external power supply, providing around 30V and the board is connected (via I2C) to an EV2400. I've attached a picture of the board showing its configuration - ignore the cable in the shot, it's for connecting my battery but is currently disconnected.
Any ideas on what might be wrong here?
Cheers,
