Adapter for small size PIC/AVR chip programming

This is a homemade adapter I made for programming SOIC/QFN size microchips that I use in my micro airplanes (http://maxoffsky.com/tech-blog/rc-micro-spitfire-airplane-build-log/). I had trouble connecting the chips any other way so I made my own universal adapter. This could also be used to do In-Circuit programming without removing the chip from the PCB. If you want an adapter to connect and fit any size m ...

Ponyprog Circuit for AVR & PIC16F84

Comments: All resistors are 1/4W.The circuit is powered by 9...15V DC or AC. When In Circuit Programming (ISP) connectors are used, is possible the programmer to be powered from target’s power source. Diodes D2 and D6 protect the regulator LM7805, when target’s power is used. ' XTAL JUMP ' is used to cut XTAL when the AVR has internal RC oscillator enabled. 'FAMILY JUMP' is used to select which ATMEL’s fami ...

Implementation USB into microcontroller: IgorPlug-USB (AVR) using pic microcontroller

Purpose of this article is to inform readers about implementation USB interface into singlechip microcontroller, which this interface directly not supports. Simply: implementation USB interface on firmware level (similar as emulation of RS232 interface in microcontrollers, which not have RS232 support). This project includes development of firmware on microcontroller side, driver development on computer sid ...

Top 8051, AVR and ARM Microcontroller Based Projects for Electronics Professionals

Microcontroller, as the name suggests, is a small controller. It is like a single-chip computer, which is embedded into other systems to work as a processing and controlling unit. A Microcontroller communicates with other devices like sensors, switches, keypads, etc. Most of the microcontroller-based projects use 8051 microcontroller, and the microcontroller programming is done by using Keil compiler. For l ...

Class D AVR

This is a project that I’ve been working on for some time now, a good part of my life, but more recently for the past month. I’m not going to go through everything as to how I arrived at this point, but I can assure you it was through a lot of trial and error. I now present to you, the class D avr amp. If I may be brief, I used 2-470 ohm resistors to combine a stereo signal, followed by a decoupling cap, us ...

Tiny AVR Microcontroller Runs on a Fruit Battery

Some of the fruit and vegetables we eat can be used to make electricity. The electrolytes in many fruit and vegetables, together with electrodes made of various metals can be used to make primary cells. One of the most easily available vegetable, the ubiquitous lemon can be used to make a fruit cell together with copper and zinc electrodes. The terminal voltage produced by such a cell is about 0.9V. The amo ...
