Software Specifications

In this section, we will use the OSS-EC SPI component ( Maxim MAX6675 ) as an example.

Intended use scenarios

After power is turned on, the temperature is obtained from the temperature sensor via SPI communication. If the temperature exceeds the upper or lower limit, it judges NG and stops acquiring temperature and Sleep.
