HX711 Load Cell Amplifier Driver

[ztnel]

Description

Raptor will need to measure the thrust produced by a BLDC motor under test. This is achieved through a load cell and amplifier. For MVP we have chosen to use the HX711 load cell amplifier to perform analog conversion and ADC conversion. The HX711 has a maximum bandwidth of 80Hz. The HX711 must demonstrate 80Hz measurement acquisition using an ISR. Measurements will be stored locally and queried by the measurement aggregation task.

The Hx711 driver will need the following functions:

hx711_status_t hx711_init(void);
hx711_status_t hx711_read(float *data, hx711_settings_t *settings);
hx711_status_t hx711_sleep(void);
hx711_status_t hx711_reset(void);

Calibration and taring will be assigned as a separate task.
