Other Parts Discussed in Thread: BQSTUDIO, , BQ27200
There is a document SLUUBD4 dated April 20176 that demonstrates how to update data memory. I see in steps 5&6 a write to 3E &3F. Where is this documented as to what is going on?
I also found this from the ti forums
Here is a direct example for updating a parameter:
An easy method to update a specific parameter is this sequence:
1. Enter CFG_UPDATE mode
2. Write the address AND the parameter data to 0x3E+ (auto increment)
3. Calculate the check sum: 0xFF - (sum of address and data) OR 0xFF
4. Write the check sum to 0x60 and the total length of (address + parameter data + check sum + length) to 0x61
5. Exit CFG_UPDATE mode
I have a number of parameters I want to update. Do I need to do this process each time for each register I want to modify?
