stm32l073z_eval_tsensor.c File Reference

This file provides a set of functions needed to manage the I2C LM75 temperature sensor mounted on STM32L073Z-EVAL board . It implements a high level communication layer for read and write from/to this sensor. The needed STM323L073 hardware resources (I2C and GPIO) are defined in stm32l073z_eval.h file, and the initialization is performed in TSENSOR_IO_Init() function declared in stm32l073z_eval.c file. You can easily tailor this driver to any other development board, by just adapting the defines for hardware resources and TSENSOR_IO_Init() function. More...
