6.1 Using USB2ANY With the TPS65219EVM

This section describes an alternate method to communicate with the TPS65219 PMIC through I2C.

While the TPS65219EVM GUI becomes available, the USB2ANY along with the USB2ANY Explorer application can be used to read and write to the PMIC registers. The U2B2ANY does not come with the EVM but can be ordered separately through ti.com. Here are the instructions:

  1. Use female-female wires to connect the SDA, SCL, and GND pins of the USB2ANY to the corresponding pins of the EVM. DO NOT CONNECT the 3V3 of the USB2ANY to the EVM. There are already 3V3 pull-ups on the EVM itself.
  2. Connect USB2ANY controller to laptop
  3. Open the "USB2ANY Explorer" application
  4. Select the second tab "I2C". There is a hidden tab bar at the top. The explorer will automatically open up to the first.
  5. Slave address is the I2C address of the device (0x30 in our case). Internal address is the register address. Set bit rate and ensure the 3.3V internal pull-ups are OFF. The SDA and SCL lines are internally pulled up already on the EVM. Use the read and write buttons to read/write to your internal address register.
