Hello Team,
I am working with one of our customers on the bq40Z50 and they are having the following issue. Thanks for your help!
I am having some troubles with the ManufacturerAccess read/write. I followed the smbus protocol as specified here (http://www.ti.com/lit/an/slua475/slua475.pdf) and have been successful in querying command words to read back the voltage, temperature, capacity, etc. I am now trying to use the ManufacturerAccess() command along with the ManufacturerData() command to query and then read back the values of the specified address. I cannot get this to work in the same communication framework as the word commands.
Does the ManufacturerAccess() and ManufacturerData() commands expect/return a PEC? The example on page 89 (http://www.ti.com/lit/ug/sluubk0a/sluubk0a.pdf) makes it seem like a PEC is not included. Could you provide some clarity on this?
Regards,
Ryan Bishop
