Atmega328p High Voltage Serial Programming

While i was expecting this huge leap in schematics and what a hobbyist can do nowadays i stil.

Atmega328p high voltage serial programming.

Avr high voltage programming fuses rescue. The atmega328p microcontroller like any other microcontroller can be quite tasking to use for a beginner. The boot program can use any interface to download. I am trying to re fuse my bricked 328p by constructing a high voltage programmer from this and similar posts.

Half a year ago i restarted one of my old passions electronics. Atmel changed the debugging feature of avr dragon with the latest firmware of avr studio 4 avr studio 5 and now it supports devices over 32 kb of. Compare with other high voltage programming options like atmel stk500 this programmer is simple to build less expensive and also easy to use. Avr hv is high voltage parallel programmer for atmel avr series microcontrollers.

The avr dragon provides in system serial programming high voltage serial programming and parallel programming as well as jtag or debugwire emulation for parts with 32 kb of program memory or less. Avr hv allows programming reading verifying and configuring avr microcontrollers with its high voltage programming interface and it connected to pc using usb interface. 2 7v to 5 5v for atmega328p. Program memory to be reprogrammed in system through an spi serial interface by a conventional non volatile memory programmer or by an on chip boot program running on the avr core.

We covered details on preparing the atmega328p microcontroller for programming by flashing the arduino bootloader on atmega328p and today s tutorial will be a follow up to that tutorial as we will look at how to program the boot loaded atmega328p microcontroller using the arduino ide. It is designed by 8 bit cmos technology and rsic cpu which enhance its performance and its power efficiency get improved by auto sleeps and internal temperature sensor.
