Ask your administrator if you think this is wrong. ======Overview======= The relay control program allows remote control of an AVR relay block.\\ It does this by sending a string that can be interpretted by the AVR microcontroller board to a remote cybiko that is connected to the RS232 port of the AVR. The project would be similar to that done with a GSM phone except that a Cybiko would be in its place. See worked up [[http://www.dbzoo.com/hw/smsrelay/index.html|GSM Solution]] ======Comments====== - Assumes that the relay board has an initial state of all OFF - Needs to handle the fact that the AVR board states and the Cybiko program can get out of sync, if either is reset independantly. The introduction of a status command that will return the state of all relays would help solve this (and also the assumption in point 1, above.). ======Code====== ^ Code ^ | {{relaycontrol_1.3.zip}} | =====Change Log===== <code> 29-May-05 1.3 Updated graphics 13-Apr-05 1.2 Xmited commands are now carriage return terminated. Modification of AVR code to self test relays on startup. RS didn't seem to work?? not sure why, reworked code. 03-Apr-05 1.1 Sends IDENT message to serialrelay to allow feedback Processes feedback information from AVR relay board to update GUI with the exact states of relays. 28-Mar-05 1.0 Initial release </code> {{tag>cybiko}} cybiko/relaycontrol.txt Last modified: 2009/11/27 17:54by 127.0.0.1
