Avrdude is a command line program, so you'll have to type in all the commands (later you'll find out how to shortcut this with a Makefile) Under Windows, you'll need to open up a command window, select Run. From the Start Menu and type in cmd and hit OK. Under MacOS X, you can use the Terminal program to pull up a command line interface, its in the Utilities folder Now in the new terminal window type in avrdude you should get this response, which is basically a simple list of what avrdude can do. There are a lot of options, lets review them quickly. Don't try to memorize them, just get a sense of what some of them may do.
There’s a sketch that you could load to your Arduino which can transform this development board into a debugger or programmer. This means we can use the Arduino to load a program to another microcontroller – in this case, the ATMEGA32. Programs (yes, sketches) can be created and compiled using the Arduino IDE then flashed to the ATMEGA32.
• -p: This is just to tell it what microcontroller its programming. For example, if you are programming an ATtiny2313, use attiny2313 as the partnumber • -b: This is for overriding the serial baud rate for programmers like the STK500. Don't use this switch, the default is correct. • -B: This is for changing the bitrate, which is how fast the programmer talks to the chip. If your chip is being clocked very slowly you'll need to talk slowly to it to let it keep up. It'll be discussed later, for now don't use it. • -C: The config file tells avrdude about all the different ways it can talk to the programmer.
Theres a default configuration file, so lets just use that: don't use this command switch • -c: Here is where we specify the programmer type, if you're using an STK500 use stk500, if you're using a DT006 programmer use dt006, etc. Xforce keygen autocad 2013 mac download. • -D: This disables erasing the chip before programming. We don't want that so don't use this command switch. • -P: This is the communication port to use to talk to the programmer. It might be COM1 for serial or LPT1 for parallel or USB for, well, USB. • -F: This overrides the signature check to make sure the chip you think you're programming is. The test is strongly recommended as it tests the connection, so don't use this switch.
• -e: This erases the chip, in general we don't use this because we auto-erase the flash before programming. • -U:r w v:[:format]: OK this one is the important command. Its the one that actually does the programming. The is either flash or eeprom (or hfuse, lfuse or efuse for the chip configuration fuses, but we aren't going to mess with those).
The r w v means you can use r (read) w (write) or v (verify) as the command. The is, well, the file that you want to write to or read from.
And [:format] means theres an optional format flag. We will always be using 'Intel Hex' format, so use i So, for example. If you wanted to write the file test.hex to the flash memory, you would use -U flash:w:test.hex:i.
If you wanted to read the eeprom memory into the file 'eedump.hex' you would use -U eeprom:r:eedump.hex:i • -n: This means you don't actually write anything, its good if you want to make sure you don't send any other commands that could damage the chip, sort of a 'safety lock'. • -V: This turns off the auto-verify when writing.
