Q: When connecting the MAX17055 evaluation kit to a PC and starting the MAX17055K Evaluation Kit Software, it displays the message NO SLAVE DEVICE.
A: This issue usually occurs when there is no battery connected to the EVKIT. The MAX17055 chip on the EVKIT takes its power from the battery, so if there's no battery connected, it is unpowered and won't respond to any of the DS91230's commands. If you don't have a battery, you can use a power supply connected to PACK+ and PACK- to make sure everything's working.
