MCP9808 temperature sensor driver implemetation written in C. This driver can be ported to different platforms implementing the I2C I/O functions defined in MCP9808_port.h file. These functions must be defined with the following prototypes:
MCP9808_Error_t MCP9808_PORT_Init( void );
MCP9808_Error_t MCP9808_PORT_Read(uint8_t address, uint8_t reg, uint8_t size, uint8_t* data);
MCP9808_Error_t MCP9808_PORT_Write(uint8_t address, uint8_t reg, uint8_t size, uint8_t* data);
void main( void )
{
float temperature = 0.0;
MCP9808_Error_t result;
result = MCP9808_Init(DEV_ADDRESS);
if( result != MCP9808_OK )
{
printf("Can't init MCP9808 driver! \n");
while( 1 )
{
/* Do nothing */
}
}
while( 1 )
{
result = MCP9808_ReadTemperature(&temperature);
if( result == MCP9808_OK )
{
printf("Temperature %.2lf",temperature);
}
else
{
printf("Error reading temperature! \n");
}
}
}
