CTL_STATUS_t ltc2309_sample_differential_unipolar(LTC2309_ADC_t *self, int channel, float *sample);
ltc2309_sample_differential_unipolar samples channel channel and channel xor 1 in unipolar differential mode with channel channel as the positive input and channel channel xor 1 as the negative input.
The object pointed to by sample is written to a value between 0 and +1 (inclusive) that represents the value sampled.
ltc2309_sample_differential_unipolar returns a standard status code.
ltc2309_sample_differential_unipolar is thread-safe if a mutex is associated with the I2C bus bus.
