6.1 PICBASIC compiler

run on everything from an XT class PC running DOS 3.3 and
higher. The compiler supports a large variety of PIC microcon-
trollers. The compiler generates machine language (ML) hex code
that may be used with other programming carrier boards. The cost
for PICBASIC compiler software is $99.95.
The EPIC programming carrier board (see Fig. 6.2) has a socket
for inserting the PIC chip and connecting it to the computer, via
the printer port, for programming. The programming board con-
nects to the computer’s printer port (also called the parallel port)
using a DB25 cable. If the computer only has one printer port with
a printer connected to it, the printer must be temporarily discon-
nected when programming PIC chips. As with the PICBASIC
Compiler, the EPIC programming carrier board supports a large
variety of PIC microcontrollers. The cost for the EPIC programming
board with the EPIC programming diskette is $59.00.
The PIC 16F84 is shown in Fig. 6.3. It is a versatile microcontroller
with flash memory. Flash memory as stated before is rewritable
