FtSwarmVotmeter

The ftSwarm can measure an externally applied voltage at the A2 input.
The measuring range of the FtSwarmVoltmeter is 0 to 4 volts.

Spannung

All other analog inputs or measuring classes determine the resistance connected to the input.

Voltage measurement is only possible at input A1 of the ftSwarm.

FtSwarmVotmeter(FtSwarmSerialNumber_t serialNumber, FtSwarmPort_t port)

Constructor to create a FtSwarmVotmeter object. If the referenced controller isn’t connected to the swarm yet, the firmware will waits until the controller gets online.

• serialNumber: Serial number of the used ftSwarm controller.
• port: Port number, FTSWARM_A2

FtSwarmVotmeter(const char *name)

Constructor to create a FtSwarmOhmmeter object. If the referenced controller isn’t connected to the swarm yet, the firmware will waits until the controller gets online.

• name: Alias name of the IO port.

float getVoltage()

Returns the measured voltage.

int32_t getValue()

Returns the the raw reading of the ADC.
