The structure of my code is strange, but I share the functions with you:
void IIS2DMC_DeviceConfig(void)
{
//The following general-purpose sequence can be used to configure the device
//The device needs 20 ms aprox to downlodad calibration coefficients from the embedded flash
//Enable temperature compensation | Output data rate = 10 Hz | Continuous mode
HAL_I2C_Mem_Write(&hi2c1, WRITE_magneto, CFG_REG_A, 1, (uint8_t *)0x80, 1, I2C_timeout);
//When the boot procedure is completed, the magnetometer enters Idle mode
HAL_I2C_Mem_Write(&hi2c1, WRITE_magneto, CFG_REG_C, 1, (uint8_t *)0x11, 1, I2C_timeout);
//Mag data-ready interrupt enable | BDU
//Who Am I?
HAL_I2C_Mem_Read(&hi2c1, READ_magneto, WHO_AM_I, 1, (uint8_t *)&IIS2DMC_data.ucWhoAmI, 1, I2C_timeout);
}
#define I2C_address_magneto 0x3C
#define READ_magneto 0x3D
#define WRITE_magneto I2C_address_magneto
typedef enum
{
WHO_AM_I = 0x4F,
CFG_REG_A = 0x60,
CFG_REG_B,
CFG_REG_C,
INT_CTRL_REG,
INT_SOURCE_REG,
INT_THS_L_REG,
INT_THS_H_REG,
STATUS_REG,
OUTX_L_REG,
OUTX_H_REG,
OUTY_L_REG,
OUTY_H_REG,
OUTZ_L_REG,
OUTZ_H_REG,
TEMP_OUT_L_REG,
TEMP_OUT_H_REG
}IIS2DMC_Registers_e;
void IIS2DMC_ReadTemperature(void)
{
HAL_I2C_Mem_Read(&hi2c1, READ_magneto, TEMP_OUT_L_REG, 1, (uint8_t *)&IIS2DMC_data.uiTemperature.byte[0], 1, I2C_timeout);
HAL_I2C_Mem_Read(&hi2c1, READ_magneto, TEMP_OUT_H_REG, 1, (uint8_t *)&IIS2DMC_data.uiTemperature.byte[1], 1, I2C_timeout);
}
And the execution is as follows:
After approximately 30 ms since the program starts, I invoke the configuration of registers, then in the RTOS every 200 ms I send the temperature reading command.
