Atmega328p High Voltage Serial Programming

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.

Atmega328p high voltage serial programming.

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. 2 7v to 5 5v for atmega328p. The boot program can use any interface to download. Atmega328p is one of the high performances avr technology microcontroller with a large number of pins and features.

Compare with other high voltage programming options like atmel stk500 this programmer is simple to build less expensive and also easy to use. 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. Avr hv is high voltage parallel programmer for atmel avr series microcontrollers. Half a year ago i restarted one of my old passions electronics.

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. I ve studied electronics in college but that happened during the middle age 20yrs ago. The high performance microchip picopower 8 bit avr risc based microcontroller combines 32kb isp flash memory with read while write capabilities 1024b eeprom 2kb sram 23 general purpose i o lines 32 general purpose working registers three flexible timer counters with compare modes internal and external interrupts serial programmable usart. I am trying to re fuse my bricked 328p by constructing a high voltage programmer from this and similar posts.

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. Avr high voltage programming fuses rescue.
