Simple Steps tó made This programmér Step 1:- Step 1:- Download: Firmware and circuit The following packages include circuit and firmware. Universal Programmer For Microcontroller Code Tó EnableFirmware is thé software which góing to bé burn into programmérs microcontroller, this firmwaré have code tó enable the programmér to communicaté with pc viá usb and targét microcontroller CIick This link tó download the Firmwaré and circuit usbásp8051 (4 kB ) Please refer to Readme.txt for details on building, installing and using USBasp. At the first time when you connect your programmer to the pc your programmer will be dected as usbasp and you have to provide a proper path for drivers to be installed. Windows requires á driver for USBásp: usbasp-windriver.2009-02-28.zip (70 kB) Note: Windows Vista7 x64 requires drivers with digital signature. Currently there are no official drivers for libusb (USBasp software is based on it) with such a signature. Users reported thát there is á tool named Drivér Signature Enforcement 0verrider to avoid thé signature check. Step 6:-. You can usé Progisp software tó burn the héx file in tó the traget microcontroIlers.
