Using JX-12 board
Preparation
Before using, user must prepare some tool and software following :
1. Personal computer which install Window 95/98/ME/2000/XP, text editor
program, MPLAB, MPASM and Miracle-PIC software
MPLAB and MPASM are licenced by Microchip Technology , for more
information please contact at http://www.microchip.com (included in CD-ROM
when order JX-877 board)
Miracle-PIC is licenced by Innovative Experiment Co.Ltd. Please
contact at www.inex.co.th (included in CD-ROM when order JX-876 board)
2. Write program, set beginning address at 0x0000 and save file in .ASM
3. Assembler .ASM file by MPASM with selected INHX8M type. So it will be
HEX file
4. Prepare DC adpator 16-20V 500mA.
Procedure
1. Constuct the curcuit, solder the components on prototype area on JX-628
2. Connect JX-628 with PC’s parallel port.
3. Supply voltage to JX-628 board, green LED at “RUN” mode is bright.
4. Press MODE switch for changing to PROGRAM mode, red LED is bright.
5. Open mPicFlash.EXE (after install Miracle PIC flash software)
6. Select PIC16F628 or PIC16F628A microcontroller.
7. Open HEX file.
8. Erase data in microcontroller by pressed
9. Check blank data in microcontroller by pressed
10. Program data in microcontroller by pressed
11. Check the result by pressed
and notice
12. In case, protect data.Select code protection in View à Configuration.
PIC16F628 can choose 4 protection types; CP All, 0200H-07FFH,0400H-07FFH and CP
OFF. These protection types have to choose before prigramming. Moreover, users
can protect data from EEPROM by select CPD in Configuration.
13. After programming completed, press MODE switch to RUN mode.
Microcontroller will runs your own program.
14. Save in desk, have to code protect. User can check by put microcontroller
in socket, open Miracle-PIC program after that, press READ then select View menu
à Program buffer and Data buffer.If showing 000, means code protect. After read
data, select File menu à Save file As and name file.HEX

Open Miracle PIC-Flash program, then select the microcontroller as figure 2,
there is 8 function buttons follow this;
Open
: Open HEX file
Save
: Save source code in HEX file
PROGRAM
: Program all data into program memory and EEPROM
VERIFY
: Test program; compare data in buffer with MCU’s data
READ
: Read data from selected microcontroller and also read
parameter
BLANK CHECK : Check blank data inside microcontroller
ERASE
: Delete data in program memory of selected
microcontroller. This function used with flash
microcontroller memory or EEPROM only.
For example, PIC16C84 or PIC 16Fxxx
Select microcontroller
: Just click at the arrow. User will see many MCU
lising.

Configuration Setting
Before programing PIC microcontroller, always fix configuraruon, go to View
à Configuration. This is detail of them.
Oscillator
- select clock mode, there are 8 types
LP - low cystal
(normally not use in JX-12)
XT - normal cystal not over 4 MHz (normally not use in JX-12 in case fit
PIC12F675 but use this mode in case fit PIC16F630 or PIC16F676 on JX-12 board )
HS - Over 4 MHz high frequency xtal (normally not use in JX-12)
EXTCLK - External Clock
(not use in JX-12)
INTRC - Internal RC circuit
EXTRC (ER) - External RC circuit (not use in JX-12)
INTRC clockout - Internal RC circuit and send fOSC/4 clock signal out
OSC2 pin. User can select OSC2 pin to RA6 port pin or Clock out pin t (not use in JX12)
EXTRC clockout - External RC circuit and send fOSC/4 clock out OSC2
pin. User can select OSC2 pin to RA6 port pin or Clock out pin t (not use in JX-12)
