Function Documentation

◆ adc_init()

void adc_init ( void )

Initialize ADC and pins for measuring current and voltage

Definition at line 16 of file measure.c.

◆ measure_current()

uint16_t measure_current ( uint16_t offset )

Measure the current on the solar panel. This function is expected to do some filtering

Parameters

offset : the offset as measured by measure_current_offset

Returns: the current in microamperes

Definition at line 49 of file measure.c.

◆ measure_voltage()

uint16_t measure_voltage ( void )

Measure the voltage on the channel for the current. This function is expected to do some filtering.

Returns: The offset
