I’m very new to vvvv, but I have some experience with MAX/MSP a few years ago…
I would like to know if it is possible to use vvvv to control two LEDs?
If it is possible I would also like to know if it is possible for vvvv to do a frequency-analysis of audio that is played through the computers sound card (by another program on the computer)? The result of the analysis is what will be used to determine weather the LEDs should be turned on or offÃ¢â‚¬Â¦
There is some info on how to get power from the RS232 port on this page: http://www.epanorama.net/circuits/rspower.html (look for Ã¢â‚¬Å“Controlling the relays with softwareÃ¢â‚¬? ~ bottom of the page):
''The serial port DTR and RTS pins can be controlled by directly writing to the I/O-port address which is the RS-232 port base address + 4.
The bits what you should set to that port are following:
Ã¢â‚¬Â¢ Bit D0: DTR pin state (0 = -12V, 1 = +12V)
Ã¢â‚¬Â¢ Bit D1: RTS pin state (0 = -12V, 1 = +12V)
Ã¢â‚¬Â¢ Bits D2-D7: Leave those to be 0
In the relay controlling circuit examples above +12V energizes the relay and -12V does not nergize it. Here is a short table of different values you send to serial port and the states different pins get:
Value DTR RTS
sent state state
0 -12V -12V
1 +12V -12V
2 -12V +12V
3 +12V +12V"
I would like to know if I would be able to utilize this using the RS232 node or in some other way? How should I setup the RS232 node?
In case you havenÃ¢â‚¬â„¢t guessed it IÃ¢â‚¬â„¢m looking for a very cheap solution to drive a couple of LEDs with vvvv.
