TIDA-010224 is designed as a reference for low-power Wi-FiĀ® cameras capable of operating from battery supplies. In order to extend battery lifetime as much as possible, most sockets are chosen to have a shutdown current in the nA range (as shown in Figure 1-1) and the TPS63802 high-efficiency buck-boost is used. In order to better understand more easily evaluate TIDA-010224, this application note describes a few additional use cases, how to set up the compiler environment if code changes are needed, how to update the firmware of CC3235 and OA7000, and how to test these use cases.
