* \section Sec_Description Project Description:
|
|
*
|
|
* Firmware for a Teensy2++ AVR-based miniboard to control four relays, using the
|
|
* same protocol used by the commercially available Silver Shield PM power outlets
|
|
* ( http://sourceforge.net/projects/sispmctl ) sold for some time. Because this
|
|
* project mimics the original device, it can be controlled using the "sismpctl"
|
|
* package included in many Linux distributions - including router-orientated
|
|
* versions such as OpenWRT - to control the board's relays.
|
|
*
|
|
* Relays 1 to 4 are respectively wired to pins C4, C5, C6 and C7 of the Teensy++ V2,
|
|
* which are the PORTC bits 4 to 7 of the AT90USB1286. The relays MUST be wired through
|
|
* a transistor, and a diode must be added in antiparallel on the relay's coil pins to
|
|
* protect the transistor from back EMF generated from the relay when the coil is turned off.
|
|
* The transistor base pin is wired to the Teensy data port through a 10K resistor. A
|
|
* LED may be also be added as a relay status indicator on each channel.
|
|
*
|
|
* The Relay coil will be driven by the transistor, but the power will come from
|
|
* the 5V from the PC's USB port: Be careful in choosing the relay to avoid overloading
|
|
* the PC, as the maximum current used MUST remains under ~450mA @ 5V.
|
|
*
|
|
* The author's tested relays are 2 Finder 32.21.7.005.2000, coil il 125ohm, which can
|
|
* handle 5A @ 250VAC. Be careful to use proper isolation if high voltages are manipulated.
|
|
* The author used Hotglue to isolate all parts of the PCB in contact with high voltage.
