I am configuring the BQ34Z100 to 2-in series cell ( LiFePo4 ) and is intending to use 4 LED and a tact switch. The schematics .
I managed to link the fuel gauge to my EV2300 . And also able to get the reading on screen.
2 questions :
1) I cannot get the Full charge capacity reading to stay at 3000mAh. I send B80B Hex to command 0x00 and the Full charge capacity changed to 3000 mAh, but after I depress the tact switch, the reading goes to 925mAh... why is this do ?
2) I cannot get the P3 and P4 to turn ON the 3rd and 4th LED. I can only get P1 and P2 signalling the 1st and 2nd LED. Even when the capacity is above 50% ~ 100%, the 3rd and 4th LED just did not light up... what configuration is wrong here ?
