Hi community,
I wanted to know about how to fetch data from the bq40z50 with I2C commands.
At first, most important for me is, which slave address the bq40z50 has, to be addressed by a microcontroller. I didn't find this in any data sheet i searched in.
The second question is how to use the commands, to fetch data by microcontroller without using the EVM. What is the sequence of bytes which are send/read to or from the bq40z50. How can I send 2byte commands on a bus system with only one byte messages, are the 2 bytes directly send after each other and which is first? Can you please explain to me the sequence of bytes in an example (let's say reading out the temperature
0x08 Temperature() - This read word function returns the temperature in units 0.1°K).
How does the Block command (for example ManufacturerAccess() 0x0071 DAStatus1) work, what is there the sequence of bytes? is there an Acknowledge between each byte?
I hope you'll be able to help me.
Kind regards and thanks,
Benjamin Geirhos
