Figure 3. TPS23881EVM GUI Start-up Window
The default device address in the GUI is set to 0x20 which matches the default configuration of the EVM
(J4 on the daughter card is installed with jumpers). The GUI sets the TPS23881 in configuration B mode
(see the
GENERAL MASK Register
section of the data sheet for details). The address can be programed
through the A1 to A4 pins and the I2C address setting in the GUI needs to match the hardware
configuration. See the
Pin Status Register
section of the data sheet for details. The startup page contains
links to the EVM user's guide, TPS23881 data sheet, E2E forum and MSP430 reference code. Four
popular PD end-equipment images are connected to the PSE switch. Links to the recommended PD
device for each end equipment are also provided.
Once the TPS23881 device is connected, click Firmware to select "Reset Factory Firmware" which loads
0x03 version of firmware to TPS23881. If wanting to load a different version of firmware, click "Load
Firmware" and choose SRAM code as desired.
