Did you buy a flat cable for PIC circuit ?

 

Do you know an electric circuit flat cable ?

 

No.1 - No.1 connection cable in flat cable is an another color, Red, White, etc,.

 

We use White jumper cable for No.1 pin of IC Data bus on our PIC Breadboard circuit.

 

This is the simple and useful.

 

We do not need to watch datasheet to find out No.1 pin of IC Data bus.

 

White jumper cable is for Clock too.

 

Because The House of Shirose is called 'Clockwork'.

When we build up electric circuits, we need voltages.

 

Normally, Red cable is for Voltage, Black cable is for Ground.

 

There are many battery sockets selling in Akihabara, Tokyo.

 

Battery sockets are, Red cable is for Voltage, Black cable is for Ground.

 

We decide to use this rule for voltages, 3.3 Volts or 5 Volts, for our PIC circuits.

 

We do not confuse anymore.

[caption id="attachment_545" align="alignnone" width="300"] (PIC16F84A and SG-8002DC on Breadboard (Photo AFP – Toshiki Shirose))[/caption]

 

To write program in Flash Memory in PIC16F84A, we must use ICSP.

 

ICSP is, In Circuit Serial Programming.

 

Pin for ICSP PIC16F84A are;

 

PIC16F84A 12 RB6 CLOCK

PIC16F84A 13 RB7 DATA

PIC16F84A 4 MCLR VTEST

PIC16F84A 14 VDD Voltage

PIC16F84A 5 VSS GND

 

Then, we will build one more socket for ICSP.

 

Connection is;

 

Socket 1 - 12 PIC16F84A RB6 CLOCK

Socket 2 - 13 PIC16F84A RB7 DATA

Socket 3 - 4 PIC16F84A MCLR VTEST

Socket 4 - 14 PIC16F84A VDD Voltage

Socket 5 - 5 PIC16F84A VSS GND

Socket 6 - N.C.

 

We will use socket for flat cable, 3 lines x 2 (or 4 lines x 2, N.C. is 6, 7, 8).

 

Socket and IC layout will be later.

 

We will build one more socket for ICSP, on our PIC16F84A CPU Board.

 

Not switch on PIC16F84A CPU Board when PIC writing.

 

Not connect CPU Direct Bus to another board.

 

This ICSP Socket connect to PIC Writer Board.

 

VDD, DC power for PIC16F84A is from PIC Writer Board, not PIC CPU Board.

 

We will make next PIC16F84A CPU Board with PIC16F84A 5 Volts, 4 MHz.

 

We want to test YAMAHA YMZ294 sound IC.

 

We will check 4.5 Volts (1.5 Volts x 3) is O.K., or not.

 

We will make 5 Volts PIC16F84A CPU Board and 5 Volts PIC16F84A Writer Board first.

 

We will make 3.3 Volts version PIC16F84A Writer Board later.

 

3.3 Volts version PIC16F84A Writer Board was confusing, because we had to use RS232C level converter IC, MAX232 or MAX232 compatible.

 

We will insert voltage lines exchange switch between PIC16F84A and ICSP socket and PIC16F84A PIC CPU Board battery.

 

This switch is 2 lines exchange switch.

 

Circuit pattern will change.

 

Voltage lines exchange switch will be toggle switch, 2 switches toggle switch x 1.

3.3 Volts IC and 5 Volts IC, both is O.K.

 

 

We still did not make another board.

 

But PIC16F84A CPU all pins are connected to out side of CPU board through Direct Bus.

 

You can make many circuit board, ex) LED test board, by your own, in out side of CPU board through Direct Bus.

 

We can not port/translate all PIC16F84A circuit boards in all of the world.

 

You can make PIC Writer board in out side of CPU board through Direct Bus too, this circuit image is in us too.

 

 

You are free, we are free.

 

You have your rights, we have our rights.

 

 

We selected 3.3 Volts with 2 batteries, but 5 Volts from AC-DC Power Adaptor is a good too.

 

 

Please enjoy your circuits.

 

 

We made Direct Bus for you and for us.

 

If you want to use removable IC sockets, you can.

 

If you want to make our circuits on braedboard, you can.

 

You are free.

If PC16F84A (18 pin), 1 pin to connect to destination pin, 10 pin to connect to destination pin.

 

Connect to destinations from 2 pin cross on IC.

 

Then PIC16F84A will be fixed on assembly board.

CPU : PIC16F84A, 18 pin

 

Crystal : SG-8002DC (3.3 Volts), 20 MHz, 4 pin (8 pin Socket)

 

By-pass condenser for Crystal Socket : 8 pin IC Socket

 

Switch : with LED, 2 pin

 

Battery : 1.5 Volts x 2, AA or AAA (It is selected by you)

 

Battery case : 2 pin

 

Direct Bus Interface Socket : Pitch 2.54 mm, 30 pin (15 pin x 2) x 1

 

2.54 mm x 40 pin = 101.6 mm, nearly equal 10 cm, then,

 

Assembly board : 10 cm x 15 cm

 

CPU socket : 18 pin x 1, 8 pin x 2 (For wire wrapping type socket, long leg type socket)

 

Assembly board legs (Spacer) : 4 cm length x 4 (For CPU Board not to electric short on your desk)

 

Wire wrapping cable

 

Wire wrapping tool

 

Drivers

 

Wire wrapping cable stripper

 

When we had done making this CPU board, we can make many PIC circuits.
