FtSwarmReedSwitch

Reed contacts respond on dtrong magnetic fields. Contactless switches can be built with the magnet building block from fischertechnik or the neodymium magnets from fischerfriendsman.

Reed contact (36120)

Reed contacts are connected to both terminals of the input. A 9V power supply is not required.

FtSwarmReedSwitch(FtSwarmSerialNumber_t serialNumber, FtSwarmPort_t port, bool normallyOpen = true)

Constructor to create a FtSwarmReedSwitch 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_A1, FTSWARM_A2, …, FTSWARM_A6
• normallyOpen (optional): true, a magnet at the reed contact will trigger the value 1. With false the reed contact without magnet delivers the value 1.

FtSwarmReedSwitch(const char *name, bool normallyOpen = true)

Constructor to create a FtSwarmReedSwitch 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.
• normallyOpen (optional): true, a magnet at the reed contact will trigger the value 1. With false the reed contact without magnet delivers the value 1.

bool isPressed()

TRUE, if the magnet activates the reed contact.

bool isReleased()

TRUE, if the magnet doesn’t activate the reed contact.

bool hasToggledUp()

TRUE if the magnet has triggered the reed contact since the last toggle call.

bool hasToggledDown()

TRUE if the magnet has released the reed contact since the last toggle call.

bool getState()

TRUE, if the magnet activates the reed contact.

FtSwarmToggle_t getToggle()

The function returns:

• FTSWARM_TOGGLEDOWN if the magnet has released the reed contact since the last toggle call.
• FTSWARM_TOGGLEUP if the magnet has activated the reed contact since the last toggle call.
• FTSWARM_NOTOGGLE, if the magnet has not changed the reed contact since the last toggle call.
