Function Documentation

◆ adxl335_get_x()

uint16_t adxl335_get_x ( void )

Returns the X channel output.

Converts the analog value of the X channel to a digital value between 0 and UINT16_MAX. It uses the formula val = scale*(res - offset1) + offset2 for the scaling.

Returns: The scaled value for the X channel.

◆ adxl335_get_x_raw()

uint16_t adxl335_get_x_raw ( void )

Returns the x channel output.

Returns: The result of the ADC conversion

◆ adxl335_get_y()

uint16_t adxl335_get_y ( void )

Returns the Y channel output.

Converts the analog value of the Y channel to a digital value between 0 and UINT16_MAX. It uses the formula val = scale*(res - offset1) + offset2 for the scaling.

Returns: The scaled value for the Y channel.

◆ adxl335_get_y_raw()

uint16_t adxl335_get_y_raw ( void )

Returns the y channel output.

Returns: The result of the ADC conversion

◆ adxl335_get_z()

uint16_t adxl335_get_z ( void )

Returns the Z channel output.

Converts the analog value of the Z channel to a digital value between 0 and UINT16_MAX. It uses the formula val = scale*(res - offset1) + offset2 for the scaling.

Returns: The scaled value for the Z channel.

◆ adxl335_get_z_raw()

uint16_t adxl335_get_z_raw ( void )

Returns the z channel output.

Returns: The result of the ADC conversion

◆ adxl335_init()

void adxl335_init ( void )

Initializes the accelerometer module.
