An AVR programmer is the device that changes the USB signals to SPI signals. This can be anything though! There are dedicated ICs that do exactly this but you can even program a microcontroller to read the USB signals and translate them to SPI. Exactly the last one is what happens with the "Arduino as ISP" sketch and the USBasp programmer.

I am presenting a best class USB Universal Programmer for both PIC and AVR Microcontrollers. In our present market the universal programmer supporting much devices with combination of PIC and AVR are not in common, they are expensive also. This programmer is very cheap which is less than ₹500(10$). It is made with easily available components.

DIY USBtinyISP-compatible AVR programmer. The USBtinyISP, available from Adafruit, is a popular open-source USB programmer which uses the SPI interface to program Atmel AVR chips like those used in the Arduino family. Having a standalone programmer is very useful when you need to burn a bootloader into eg. ATmega328P in an Arduino Pro Mini.

- A High Voltage AVR programmer, primarily used on ATtiny devices to set fuses when the reset line is used for I/O. - Arduino as ISP, 5V and 3v3 (counts as two of the functions) - NOR Flash EEPROM programmer (quickly copies from an SD card to NOR Flash) The board uses common AMS1117 LDO voltage regulators to get 5V and 3v3.

This is simple to build AVR programmer for Atmel microcontrollers from AVR family. The microcontrollers must support serial programming. AVR programmer is connected to a PC through the RS232 serial interface and can be used with the PonyProg or Avrdude software programmer. AVR programmer is quite simple and it is based on the SI-Prog from the author of PonyProg software.

2010年12月14日 · Yeah, you might be able to pick up some commercial PIC programming hardware for cheap, but an AVR can be programmed with a parallel cable and three resistors, and more sophisticated DIY plans are ...

2017年9月20日 · Note: To burn the firmware to Attiny2313, you’ll need another programmer, you are adviced to use any of these simple programmer that you can use with Serial port, or Parallel port. Programming Instructions for downloading firmware to Attiny2313. Download the USB driver and also firmware for v2.0 from Ladyada site.

A programmer adapter is one of the first things to get when starting with microcontrollers. Luckily, it is not hard to build a working programmer almost for any microcontroller, as there are tons of open-source projects. I decided to make my own stk500 compatible programmer, which is taken from tuxgraphics.com. I did not look for the same parts …

2013年1月2日 · 3. Assembler and programming software.. Windows: AVR Prog application that comes with AVR Studio. www.atmel.com AVR Studio is a complete development package and includes a fairly good simulator.. A few notes on variations and resources. The design is clever and works very well. It is an amazing demonstration of what can be done in 1K or ROM and only a 3 level deep stack.

2011年5月26日 · So ISP allows programming of a AVR microcontroller in circuit, avoiding the need to constantly take it in and out of the programmer and the subsequent bending of pins. Advantage. This simple AVR Programmer will allow you to painlessly transfer hex programs to most ATMEL AVR microcontrollers without sacrificing your budget and time; This AVR ...
