Hello,
I found a mistakes in the Figure 1, Flowchart for Updating the Gauge Configuration Parameters in the Quick Start Guide for bq27621-G1 (Rev. A)
From the flow chart (wrong! OK for BQ27421):
OLD_DC[2] = I2CReadBlock(0x4A, 2, 100) - should be 0x43
OLD_DE[2] = I2CReadBlock(0x4C, 2, 100) - should be 0x45
OLD_TV[2] = I2CReadBlock(0x50, 2, 100) - should be 0x49
OLD_TR[2] = I2CReadBlock(0x5B, 2, 100) - should be 0x54
The same addresses are for the writing!
I lost a lot of time to understand what is wrong in my configuration!!!
Please, fix it!!
