TECHNIQUES FOR AUTOMATED SERIAL DEVICE INTEGRATION TO MICROCONTROLLER
Methods, systems, and devices for automated serial device integration to a microcontroller unit (MCU) of a wearable device are described. Hardware (HW) components of the MCU of the wearable device may receive an interrupt command from sensors of the wearable device via one or more buses during a time interval that processing components of the MCU are in an inactive state. The HW components may perform a read operation to read data from a preconfigured buffer address of the sensors during the time interval that the one or more processing components are in the inactive state and based on receiving the interrupt command. The HW components may then perform a write operation to write the data to a preconfigured memory address of the memory during the time interval that the one or more processing components are in the inactive state.
