Microchip PIC® 8-bit microcontrollers are quite popular amongst hobbyists, and I’ve used them for a long time in several of my projects. They are very cheap, use only 35 assembly instructions that are easy to learn, and most importantly they use flash memory, which gives you the possibility to program the device virtually as many times as you want during your experiments. Up until now I’ve used a simple serial interface and picprog to program them under Linux, but sadly the trend is not to include a serial port anymore on new computers/laptops. Of course there are USB programmers on the market, but quite often their price exceeds 30€ and not all of them work well on Linux. Also a commercial programmer usually supports hundreds of different chips, while all I needed was a simple and cheap way to program, say, the four chips I work with most of the time. So, with the introduction of the Raspberry Pi, and the possibility to control external hardware through its GPIO connector, I thought it would be worth spending some time to design a simple interface and write a software to program some PICs. The result of about a week of work is rpp – a Raspberry Pi PIC Programmer that uses the GPIO connector.

LadyAda some time ago build a low-cost AVR ISP. In μC.net there was a further development of the project under the name “AVR ISP Stick” or “People’s Programmer” I take up the project and develop it further with the permission of Ada.

Since this is a well working low budget AVR ISP progammer (by Thomas Fischl), I offer a compact single-sided THT-SMD combined layout. The circuit is identical to the official programmer, so the original firmware can be used with this board. This programmer is supported by avrdude. One of the main features is that the low speed USB protocol stack is realized directly with the used AVR controller, which makes this programmer a low budget one, about 5EUR material costs. Notice however that this programmer cannot be used with 3V3 systems without an additional level shifter.

The PICkit™ 2 Programmer/Debugger is a low-cost development tool with an easy to use interface for programming and debugging Microchip’s Flash families of microcontrollers. The full featured Windows programming interface supports baseline, mid-range, PIC18,8-bit, 16-bit, and 32-bit microcontrollers, and many Microchip Serial EEPROM products. With Microchip’s powerful MPLAB Integrated Development Environment (IDE) the PICkit 2 enables in circuit debugging on most PIC microcontrollers. In-Circuit-Debugging runs, halts and single steps the program while the PIC microcontroller is embedded in the application. When halted at a breakpoint, the file registers can be examined and modified.

USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simply consists of an ATMega48 and ATMega88 an ATMega8 and a couple of passive components. The programmer uses a firmware-only USB driver, no special USB controller is needed.
- Works under multiple platforms. Linux, Mac OS X and Windows are tested.
- No special controllers or smd components are needed.
- Programming speed is up to 5kBytes/sec.
- SCK option to support targets with low clock speed (< 1,5MHz).

This simple COM PORT based AVR atmega Programmer will allow you to painlessly transfer hex programs to most ATMEL AVR microcontrollers without sacrificing your budget and time. It is more reliable than most other simple AVR programmers available out there and can be built in very short amount of time.
AVR programmer consists of in-circuit serial programmer (dongle) and small pcb with a DIP socket where you can fit your microcontroller and have it quickly programmed.

Recently, I needed to have a bunch of AVRs programmed… A big bunch… And as I am really lazy when it comes to do repeated procedures, I decided to make a robot to do this for me.
