Introduction: This application note demonstrates how to control Serial Plix with a PicStic 1, 2, 3, or 4 micro-controller.
Background: The Serial Plix is an 18-pin CMOS chip, which provides an intelligent communication interface between a serial port and X-10 AC power-line control modules. Using our example software and a TW523 power-line adapter module, you'll see how easy it is to remotely control appliances and lights through the power lines.
How it works: Serial Plix removes the burden of complex X-10 programming protocol from the designer by providing a simple serial interface. It takes care of the complex zero-crossing timing for sending and receiving X-10 commands so you don't have to. An otherwise simple embedded controller can now also feature X-10 power-line control by simply adding a Serial Plix chip to the design. The following schematic demonstrates all of the connections needed.
Program Listing: ‘ This program demonstrates how to control Serial ‘ Plix using a PicStic 1, 2, 3, and 4 with PicBasic. Symbol SO = 0 ‘Define serial out pin ‘to be PB0 on the PicStic Pause 1000 ‘Delay for voltage levels ‘to settle. Begin: Serout SO,N9600,("$UONA1602") ‘Send the command ‘to turn on light ‘A16. PAUSE 3000 ‘Delay to allow ‘serial plix to ‘complete it's ‘command. Serout SO,N9600,("$DIMA1610") ‘Send the command ‘to dim light ‘A16. PAUSE 10000 ‘Delay to allow ‘serial plix to ‘complete it's ‘command Serout SO,N9600,("$BRTA1610") ‘Send the command ‘to brighten light ‘A16. PAUSE 10000 ‘Delay to allow ‘serial plix to ‘complete it's ‘command Serout SO,N9600,("$UONA1602") ‘Send the command ‘to turn off light ‘A16. PAUSE 3000 ‘Delay to allow ‘serial plix to ‘complete it's ‘command Goto Begin ‘Start the program ‘over.
