2 Using JX-877 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 (included in CD-ROM when order JX-877 board) Miracle-PIC is licenced by Innovative Experiment Co.Ltd. Please contact at (included in CD-ROM when order JX-877 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 Connect JX-877 with PC s parallel port. 3. Supply voltage to JX-877 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 PIC16F877 or PIC16F877A 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 Configuration. PIC16F877 can choose 4 protection types; CP All, 1000H-1FFH, 1F00H-1FFH 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 Program buffer and Data buffer.if showing 000, means code protect. After read data, select File menu Save file As and name file.hex 2 JX pin PIC microcontroller project board

User can edit by select memory position and input value directly or use Fill Progran Bufer Function Data Buffer (F12) - shows all data EEPROM (figure 3). User can edit data by select memory position and input value directly or use Fill Progran Buffer Function Configuration (F9) - shows detail of PIC configuration. User can enable or disable all parameter. Count Program use this function in JX-877) - show number of programmed microcontroller (not Stay on top - Make the program always on the top Figure 2 : Program buffer window, user can see all code and edit any address 4 JX pin PIC microcontroller project board

Figure 3 : Data buffer window, user can see all data in EEPROM within microcontroller and edit any address Figure 4 : Configuration window Configuration Setting Before programing PIC microcontroller,

Oscillator - select clock mode, there are 4 types (for PIC16F877-20/P) LP - low cystal (not use in JX-877) XT - normal cystal not over 4 MHz (not use in JX-877) HS - Over 4 MHz high frequency xtal RC

This is detail of them. Oscillator - select clock mode, there are 4 types (for PIC16F877-20/P) LP - low cystal (not use in JX-877) XT - normal cystal not over 4 MHz (not use in JX-877) HS - Over 4 MHz high frequency xtal RC - External RC circuit (not use in JX-877) Code protection - Use for selceting protection mode. It can protect data in PIC16F877 microcontroller is 4 modes include : ALL, 1F00H-1FFFH, 1000H-1FFFH and OFF. Select CPD box for protection data in EEPROM. Configuration - To select special ability of PIC miocrocontroller, it depends on type of microcontroller. For PIC16F877 has 6 types; WPT (watchdog Timer) PWRT (Power-up Timer) BODEN (Brown-out Reset) LVP (Low Voltage program) - Enable programming to PIC microcontroller with low voltage instead of +12V (Should not use with JX-877) JX pin PIC microcontroller project board 5

6 ICD (In-circuit Debugger) - Edit program memory in position OX0100(100H) up via RB6 and RB7 so RB6 and RB7 is not work(no use in JX-877) WRT (Flash progran write) - If select this function, users can program data into flash program memory via resistor EECON. On the other hand, no select this, the program in the memory have to do via RB6 and RB7 in normally. Device Select type of PIC microcontroller Command Arrange reading, writing and testing data in microcontroller memory Program Chip (F4) - Program code and data to microcontroller as PROGRAM buttom Verify Chip (F5) or incorrect as VERIFY buttom Read Chip (F6) Erase Chip (F7) Blank Chip (F8) as BLANK CHECK button Option Separate 4 parts; - Check writing data in PIC microcontroller correct - Read data from microcontroller as READ buttom - Delete data in PIC microconrtoller as ERASE buttom - Check blank data in PIC microcontroller memory Part1 Program/Verify Program - check latest programming in microcontroller with buffer. Program/Verify Data - check data in microcontroller memory after latest programming Program/Verify ID - checking ID value in microcontroller after latest programming (not use in JX-877) Program/Verify Configuration - check configuration value after latest programming Part2 Special feature in Miracle-PIC programmer software Verfy while program - check data while program microcontroller. If occur the faults, program will stop in suddenly. Auto verify after program - check data after completely programming automatic.
