The EPIC Programmer is compatible with both the PicBasic and PicBasic Pro compilers The programming carrier board (see Fig. 1. 3) has a socket for inserting the. .. PicBasic compiler. The Pro version offers an enhanced and richer basic command syntax than is available in the PicBasic compiler package. A few of the addition­ al commands that can be found in the Pro version allow the use of interrupts, direct control of LCD modules, DTMF out, and X 10  commands, to name a few While the PicBasic Pro is a more sophisticated package, the compiler does not handle two of my favorite Basic commands, peek and poke. Although the commands are listed as “functional” in the Pro manual, it is emphasized that... code  and  accessing  the different  aspects  of  the microcon­ troller’s features and memory The high­level  language  I  use  is  a derivative  of  the Basic  language.  It  is called  PicBasic.  (The PicBasic  and  PicBasic  Pro  compilers  used  to write PicBasic  programs  are  products  and  trademarks  of  microEngineering  Labs, Inc.)  PicBasic  is  similar  to the PBasic  language ... ning. I recommend beginning with the 16 F84 PIC microcontroller. The 16 F84 is an 18 ­pin dip chip with 13  I/O lines and has 1K � 14  of rewritable memory The rewritable memory allows you to reprogram the PIC chip up to 10 00 times to test  and  troubleshoot  your  programs  and  circuits.  The minimal  support components are a 5­V dc power supply, oscillator (4.0­MHz crystal), and one pull­up 1 4­W resistor (4.7­k�) 16 F84 PIC Microcontroller The PIC 16 F84 microcontroller is shown in Fig. 1. 4. It is a versatile microcon­...
