Temperature Logger with ATtiny817 and SD Card-v2
This application note describes the implementation of a temperature logger, demonstrating use of several peripherals of the ATtiny817 AVR device. The TWI peripheral is used to communicate with an Atmel AT30TSE digital temperature sensor. The asynchronous RTC module is used to generate a timestamp for each temperature measurement, and the data is written to an SD card via an SPI interface using the ELM-Chan Petit FAT file system library.
