Programming Procedure

7 Experiments

Use of the experiment push buttons and LEDs:

The K8048 is equipped with a max. of 4 test inputs that can be operated manually with

SW1,SW2,SW3 and SW4.

The device also has 6 diagnostics LEDs that enable the user to simulate outputs.

which push button or LED.

Remarks:

he I/O lines coming from a pushbutton have to be configured as inputs in the source

(a 1 in the TRIS-register

for that particular entrance

The I/O lines connected

with a LED must be configured as exits in the sources (a 0 in the TRIS-register for that

particular entrance).

Selecting an oscillator with the jumpers

These jumpers allow you to select which IC socket crystal X1 uses.

Place the shunts in locations JP1 & JP2 for use with the 14-pin socket (e.g. PIC16F630).

Place the shunts in locations JP3 & JP4 for use with the 18-pin socket (e.g. PIC16F627).

Place the shunts in locations JP5 & JP6 for use with the 28-pin socket (e.g. PIC16F87x).

No selection can be made for the 8-pin socket since you would lose two I/O's. With this

particular experiment board you can only use the internal oscillator with this socket.
