High Voltage Serial Programming Attiny

Arduino high voltage programmer eraser for attiny based on recover bricked attiny using arduino as high voltage programmer this program restores the default fuse settings of the attiny and can perform a chip erase lock bits reset.

High voltage serial programming attiny.

You don t need to purchase a hvp high voltage programmer or search for an old pc with parallel port to recover attiny. At attiny13 factory settings fuse bits. Developer programmer http mprog ru assures us that everything is done in accordance with the datasheet. The fuses can then easily be changed with the programmer you use for uploading your program.

Using wayne holder s excellent attiny fuse reset posts as a starting point this little device is able to reset the fuses on many attiny devices. T his arduino sketch is useful for rescuing attiny microcontrollers rendered useless by incorrect fuse settings. Just build a small circuit plug it into arduino board upload a sketch and you are good to go. A similar result if you include dwen.

High voltage serial programming hvsp is the high voltage protocol for 8 and 14 pin attiny mcus. With this mechanism it is possible to bring the mcu back to life. Connecting your standard arduino hvsp requires 7 signals including power and ground as shown in this illustration. Included is a bit rstdisbl after this chip is not available for high voltage serial programming.

Atmel attiny datasheet chapter high voltage serial programming describes alternative way of programming attiny microcontroller.
