ACCESSING DATA FLASH Of BQ27541

Other Parts Discussed in Thread: BQ27541

Hi,

I'm using pic16f690 (by microchip MPLAB°) for programming a bq27541, but i have a problem to change the value of the pack configuration.

I have written the flowwing  instructins.

Blockdatacontrol() : 0x61->0x00

blockflashclass : 0x3E-> 0x40

dataflashblock : 0x3F->0x00

blockdata : 0x40 and 0x41 -> (0x01 an 0x00 respectily)

And it is the good configuration for the pack configuration but i don't know the value of checksum of the block and how to change it.

i have tried to change the value of blockdatacheksum but nothing happened

Can someone help me please ?

Thanks
