Welcome to ADT74x0-STM32 👋

STM32 library for the I2C temperature sensor Analog Device ADT7410 or ADT7420

Default Configuration (on startup or after reset)

• Conversion mode : Continous
• Interrupt Mode
• Resolution : 13 bits

What is not implemented ?

• Continous Conversion

I2C Configuration

• SCL frequency : up to 400 kHz

INT and CT pins

These pins can be configured according to the temperature detection registers (high, low, critical and hysteresis). You will find all associated functions in the source code.

Resolution

This IC can be configured in 13bits or 16bits. The temperature value will be automatically calculated according to the resolution setting.

Usage

#include "ADT74x0.h"

ADT74X0 temp;

int main(void) {
	temp.adti2c = &hi2c1; // Your I2C Handler
	
	ADT74x0_Init(&temp, 0x48); // I2C address depends of A0 and A1 pins
	ADT74x0_Reset(&temp); // Optional
	ADT74x0_SetResolution(&temp, ADT74X0_16BITS); // Put the device in 16 bits resolution
	
	if (ADT74x0_ReadTemp(&temp) != HAL_OK) {
	    Error_Handler();
	}
	printf("Raw value : %d - Temperature Value : %f\r\n", temp.raw_data, temp.deg_data);
}
