Guide to use USBASP Programmar to burn Hex File to AVR Microcontroller.

Introduction : Robo India USBASP Programmer.

USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simply consists of an ATMega8 and a couple of passive components. The programmer uses a firmware-only USB driver, no special USB controller is needed, and that makes it low cost USB programmer.

Important features are:

Works under multiple platforms. Linux, Mac OS X and Windows are tested.
Jumper for 5v supply.
Header Pin to provide easy interface for various ISP header pin.
SCK option to support targets with low clock speed (< 1.5MHz).

Installation:

Install USBASP as simple usb device.

Download : Drivers 32&64 bit

Here is a wonderful guide on how to install USBASP on windows 8. click here

Uploading hex file to AVR Microcontroller:

To transfer the Hex file to controller we require a software to access USBASP. There are lots of softwares available on internet.Software which we find easy to use with all features is Prog ISP.

Download:

Note: no need to install install Prog ISP just unzip the file and click on progisp.exe executable file to launch the software.

Hardware Set up:

Connect USBASP to your AVR microcontroller board using 6 pin connectors, where 5v is optional, if your board is already powered by some external 5v supply than remove the jumper(vcc on/off).

Troubleshooting:

Prog ISP will show error in case:

Supply is not provided to target controller.
wrong connection to Target microcontroller.
USBASP not detected.

Note: keep the Jumper (J1) always connected.

Getting Started with Prog ISP:

Select Chip: Select the microcontroller for uploading Hex file.
Load Flash: This tab is used to select the Hex file,Click this tab to open browse window and select the Hex file.
Task Window: Select the operation which you want to complete. basic operation required to burn hex file are shown above.
Auto: Click on this tab to start burning the hex file along with all the operation checked in task box.
Fuse: This tab is used to open Fuse window as shown below,where you can read or write low and high value of fuses.

Steps to Upload Hex File:

Install USBASP Programmer.
Connect Hardware.
Select microcontroller in ProgISP.
Load Hex File.
Click Auto tab to transfer the code.

Download Keil

Here is the download link of Keil. You can download it and install it very easily. We are using C51 version for 8051 devices.

Use Keil to write programs for 8051 Microcontroller

Start the Keil software. Go to the Project > New Project then choose a location to store your program, and give a name and Save.
Now in the next window select the device from different manufacturers. We are selecting Microchip, and then by expanding we are selecting AT89C51 device and click ok.
Now go to the New in the menu and select New. It will open a new editor to write code.
Go to the save option and save the program file with .c extension.
Write the code for 8051 Microcontroller. (Here we are using a code for blinking LED in 500 ms)
Now from the left panel, select Source Group 1, and Add Existing Files to Group ‘Source Group 1’. Then select the program (c file) then add and close
.
Now go to the Project > Build Target to build the project. If there is some error the building will be failed, after correcting the errors it can be build.
Now click on the Target1 from the left panel and select Options for Target ‘Target1’. Then set the xtal (MHz) value to 11.0592. Check mark on the Use On Chip ROM. Then go to the output tab. In this tab check Create Hex File, and click OK. Then build it again.

By uploading this hex file into the 8051 microcontroller the program can be loaded into it. And it will work.
