Please install USB dongle driver on the computer, and connect the dongle to the SCL/GND/SDA connector on the EVM 2. Connect the battery pack to TP1/BATT and TP2/GND connectors, take care of that the battery positive/negative terminal must not be reverse connected. 3. If using a battery emulator, preset the battery emulator to 3.8V/5A and turn off the emulator, connect to TP1/BATT and TP2/GND, then turn on the emulator output. 4. Verify the USB dongle successfully connects the MP2696A to the computer (no warning shows on the top of the GUI). 5. Now the charging and boost parameters can be controlled by the GUI interface.
