Use of Programmer????

Can any one provide any video or link where instuctions are given on how to use a programmer?

If you can be specific with what programmer you are using, it would be easy to give you the answer.. all the instruction to use the programmer is usually given in help of the programmer / software you use or manual of the product.........

it is a USBasp

Maybe these can help:

can anyone explain what is a USB ISP and how to use it

Hi,

A USB ISP (In-system programming) is a standard piece of hardware to transfer the .hex program file created on a PC to a Micro.

The .hex file is sent out of the PCs USB port into the USB ISP which then controls the data being loaded into the SPI port of the target AVR chip.


Are you just trying to understand what one is, or how to actually use one ?

actually i wanted to understand both

Hi,

The links given by the guys above are good, but I assume they are a bit advanced for what you know now ?

I assume you have decided to use the AVR chips to learn on ? - have you decided on Assember or C to code with ? - have you bought any hardware yet ?

If AVR is the way you are going then perhaps have a look at the Arduino system, particularly the Uno board.

It has it own built in 'bootloading programmer' so you just write your code and it automatically loads the code into the chip for you and then runs the program.
Arduino - ArduinoBoardUno

Its a really good tool to get you going with the masses of free software and importantly beginners tutorials.

You can download the free Arduino IDE and do the tutorials without the need of buying any hardware , so give it a try , takes less time than posting here !!

im nt using a arduinoboard ive bought a At89s52 and a development board and USB ISp

Hi,

There are a lot of those AT dev boards, all slightly different, you do not say which model you have?

Does it come with any tutorial or guides, I assume none or little you can follow ?

You first need to create or get your .hex file from your own program code or an example, say a simple led flasher program.

Then on the PC you start PROGISP and Read in the .hex file, then with the USBISP connected to the PC and Dev board you 'Program' the chip with the code.
Once thats programmed in, you power on your dev board and the program should run, typically a led will flash.

Cannot be any more detailed than that, as you may need to set other parameters in PROGIS, like the Oscillator you are using etc.

Have you settled on a development IDE or compiler distro to develop and program your AVR dev board?

If so, I maybe able to point you to some helpful tutorials.
