Hello,
I have connected the BQ27X00-TESTER to my current product that has a BQ27200 device populated. Between the tester and my product, I've wired...
* PROG to our PGM (pin 10) of BQ27200
* BAT- to our VSS (pin 3) of BQ27200
* HDQ/SDA to our SDA (pin 5) of BQ27200
* SCL to our SCL (pin 4) of BQ27200
After doing this, we power on our product, then power up the tester board with an external 10V DC source. Then we bring up the BQ27X00-TESTER application on a PC and attempt to perform a "READ EEPROM" unsuccessfully. All registers show "0x5" as their read data, but I see no actual activity on the I2C SCL/SDA lines on an attached scope.
Any ideas what we are doing wrong to not see any I2C activity between TESTER and our BQ27200 platform?
Thanks!
Joe
