switch_4.zip 9k 1999-Jan-30 Software upgrade for the Audio/Video Switcher project. Since the article first appeared in CQ-TV 175, I have been asked on many occasions to rewrite the program to use the PIC 16c84 device instead of the 16c54. The '54 is rather more difficult to program without special hardware but it is much cheaper than the '84. As a new feature had to be added to the switcher I use in my shack, I took the opportunity to not only update the functionality but to change to the more popular processor type. The new code is available on the BATC Web pages and CD. If you already have one of the switchers, there is no need to upgrade it unless you need to create the ?ABCD? tone codes that are not normally available on keypads. As this was specifically what I needed to do, the feature is now included in the new version and is activated by holding the ?TO? tone selector key down while pressing one of the 1,4,7 or * keys. Holding the key down changes column 1 of the keypad into column 4 so the ?1? key becomes ?A?, ?4? becomes ?B?, ?7? becomes ?C? and ?*? becomes ?D?. Because of the way the keypad is scanned, it is necessary to release both keys before making another selection. There is no hardware change except for the microcontroller itself of course.
