Class ADC: Controls the Teensy 3.x, 4 ADC
Returns the analog value of the special internal source, such as the temperature sensor.
It calls analogRead(uint8_t pin) internally, with the correct value for the pin for all boards. Possible values: TEMP_SENSOR, Temperature sensor. VREF_OUT, 1.2 V reference (switch on first using VREF.h). BANDGAP, BANDGAP (switch on first using VREF.h). VREFH, High VREF. VREFL, Low VREF.
- Parameters
-
| pin | ADC_INTERNAL_SOURCE to read. |
| adc_num | ADC_X ADC module |
- Returns
- the value of the pin.
| int ADC::analogRead |

uint8_t |

|
) |
| |
Returns the analog value of the pin.
It waits until the value is read and then returns the result. If a comparison has been set up and fails, it will return ADC_ERROR_VALUE. This function is interrupt safe, so it will restore the adc to the state it was before being called If more than one ADC exists, it will select the module with less workload, you can force a selection using adc_num. If you select ADC1 in Teensy 3.0 it will return ADC_ERROR_VALUE.
- Parameters
-
| pin | can be any of the analog pins |
| adc_num | ADC_X ADC module |
- Returns
- the value of the pin.

) |
| |
Returns the differential analog values of both sets of pins, measured at the same time by the two ADC modules.
It waits until the values are read and then returns the result as a struct Sync_result, use Sync_result.result_adc0 and Sync_result.result_adc1. If a comparison has been set up and fails, it will return ADC_ERROR_VALUE in both fields of the struct. This function is interrupt safe, so it will restore the adc to the state it was before being called
- Parameters
-
| pin0P | positive pin in ADC0 |
| pin0N | negative pin in ADC0 |
| pin1P | positive pin in ADC1 |
| pin1N | negative pin in ADC1 |
- Returns
- a Sync_result struct with the result of each differential ADC value.
