Creates hex file for ISPnub ( from given programming instruction script. ISPnubCreator is written in Java.


Example of programming instruction script, programming an ATmega8 ("../test..main.hex" contains the firmware for the target Atmega8). "test.ispnub":

CONNECT 2000000                           ; connect with SCK = 2 MHz 
SPIVERIFY 0x30, 0x00, 0x00, 0x00, 0x1E    ; check signature byte 0x00 (0x1E = manufactured by Atmel)
SPIVERIFY 0x30, 0x00, 0x01, 0x00, 0x93    ; check signature byte 0x01 (0x93 = 8KB Flash memory)
SPIVERIFY 0x30, 0x00, 0x02, 0x00, 0x07    ; check signature byte 0x02 (0x07 = ATmega8 device)
SPIWRITE  0xAC, 0x80, 0x00, 0x00          ; chip erase
WAIT 2                                    ; wait 20 ms
FLASH ../test/main.hex, 0, 64             ; flash given hex file starting at flash address 0 with pagesize 64
DISCONNECT                                ; disconnect SPI
DECCOUNTER 10                             ; allow 10 programming cycles

Call ISPnubCreator to create the hex file for ISPnub:

java -jar ISPnubCreator.jar test.ispnub ispnub.hex

Now the generated "ispnub.hex" can be flashed with your favorite programmer into the ISPnub module.


Ant is used to build the application from Java source code. To create the JAR file, use

ant jar
