I just made this Arduino full 8-pin RS-232 level shifter 'shield' a few weeks ago, and got the boards today! It can act as a sniffer for RS-232 traffic, or hit the switch to disable pass-through and let the Arduino take over as an intermediate or to emulate either host/peripheral devices. https://oshpark.com/shared_projects/Vs4zWf41 So far I test fit the switch and DB9 ports and they fit, will work on soldering it up tomorrow and testing it! P.S. my target for this is to build an Arduino-controlled serial mouse, I wanted the option to sniff the protocol and also have the ability to disable the actual mouse and instead send mouse commands with the arduino. The switch was really a peace-of-mind thing security type thing, but since I didn't put space for diodes it isn't really a complete solution for keeping the arduino completely out of the picture when the switch is pressed (oops, if this works I'll probably make another rev). _______________________________________________ dorkbotpdx-blabber mailing list [email protected] http://music.columbia.edu/mailman/listinfo/dorkbotpdx-blabber
