Functions

void set_adc_mux (int which)
void analog_init (int start_conversion)
 Initialize analog ports. Will start running a loop if start_conversion is ADC_START.
unsigned int analog8 (int which)
 Returns an 8-bit analog value from the look up table. Use this instead of analog_get8.
unsigned int analog10 (int which)
 Returns an 10-bit analog value from the look up table. Use this instead of analog_get10.
void analog_start_loop (void)
 starts the analog loop. Doesn't do anything if the loop is already running.
void analog_stop_loop (void)
 Stops the analog loop. Doesn't do anything if the loop is already stopped.
unsigned int analog_get8 (int which)
 Read an 8-bit number from an analog port. Loop must be stopped for this to work.
unsigned int analog_get10 (int which)
 Read a 10-bit number from an analog port. Loop must be stopped for this to work.
int wheel (void)
 Read the position of the wheel.
 ISR (ADC_vect)

Variables

int adc_loop_running = 0
int adc_current_port = 0
adc_t an_val [11]
