Other Parts Discussed in Thread: BQ34Z100, EV2400, BQSTUDIO
Tool/software: Code Composer Studio
I am training with EV2400 and Bq34Z100 EVM.
My configutration :
* One cell li-ion
* I prectise, so I use a voltage source ajusted to 4000mV, connected betwen Bat + and Bat- of EVM.
* I'am in ''unseal full acces mode'' (It's OK)
*In data memory menue / Confuguration : ''Serial Number'' is set to 1 . I presume it means one cell.
*In data memory menue / Calibration : ''voltage divider'' is st to 5000 mV
* On the dashboard, the batterie is green and indicate 3995mV (78%) . The 2 arrow of I2C are green. So it's ok.
* In ''Perform calibration menu''. I've calibrate CC offset. Ok. I 've calibrate Board offset. OK . I have calibrate internal Temp . OK. I've calibrate succesfully the curent (-1000mA) OK
* But it is impossible to calibrate the voltage of the system? I 've check the voltage box on the screen. The voltage gauge indicate the same value than in the dash board 3994mV. It's OK.
I have mesure the voltage of my source: 3999mV. I 've entered this value in the label ''Applied votage . I've launch the calibration (knob ''calibrate Gas gauge'')
A read mesage error apear on the left botoom of the screen. ''Calibration - A read of data written failled comparison''. Hi !!!!
So what appens? I dont understand. Please, can you explain me the problème?
What can I do ?
Thanks by advance for your answer.
Best regards
