With complementary software, AVRprog2 programmer represents a great tool for all those working with Atmel’s AVR microcontrollers. The microcontroller connects to the AVRprog2 programmer via 6 lines, two of which are +5V and GND and others are MOSI, MISO, SCK and MCLR. Unlike programmers whose operation is based on bootloads (and which need to give away part of their memory to a bootload program) AVRprog2 programs the microcontroller externally so that the entire memory is available for the programmer.

Keyboard Shortcuts

New version of software includes a number of shortcuts which facilitate programming:

• Alt-E Erase
• Alt-B Blank check
• Alt-W Write
• Alt-V Verify
• Alt-R Read
• Alt-D Change MCU
• Ctrl-S Save
• Ctrl-O Open (Load)
• Ctrl-R Reload

Command Line

Alternatively, you can use the AVRprog2 programmer from the command line. Here are the command line parameters:

• -w Write to AVR
• -v Verify
• -r Read from AVR
• -e Erase AVR
• -p AVR name (for example ATMEGA16, ATMEGA8535s...)
• -f Filename (use " as delimiters)

Examples:

AVRFlash.exe -w -pATMEGA16 -v -f"C:\somefile.hex"

This will program the AVR using C:\somefile.hex and it will verify the write.

AVRFlash.exe -r -pATMEGA16

This will read the AVR contents into on screen buffer.

AVRFlash.exe -e -pATMEGA16

This will erase the AVR.
