Original question:
BQ4050EVM-561: 关于bq4050电量学习
Design Capacity set to 400mAh successfully
Why was the Full Charge Capacity set to 400mAh unsuccessful and kept at the default 3000mAh
Why is it that
您好
1，FCC是放电以后更新的
2，FCC更新的条件请参考TRM 1.1.3 Capacity Learning (FCC Update) and Qualified Discharge
3，请确认参数是否正确写入。
4，如果是修改容量一般修改design capacity就可以了
design capacity 修改成功了，但读取剩余容量大值还是3000mA，我不知道为什么会这样,不知道是不是FCC没有修改成功
您好，建议您做几个循环学习更新一下FCC
我现在只有BQ27200芯片，自己画的PCB。ROM design capacity 修改成功 400mah , 0X3C读取出来是正确
FullChargeCapacity() 是3000mah，读取来的剩余容量大值还是3000mA，是因为FullChargeCapacity() 没有修改成功吗？
我是不太理解FCC什么时候才能更新，自习要注意什么。
您好,上面帖子中有回复FCC是放电以后更新的, 不是修改了design capacity 就会改变.
