Microcontroller programmers are specialists who develop software for microcontrollers—small, integrated circuits that control various electronic devices and systems. They write code that enables microcontrollers to perform specific tasks, such as sensor readings, motor control, or communication with other devices. This often involves programming in languages like C or C++, configuring hardware peripherals, and debugging to ensure the software interacts correctly with the hardware. Their work is crucial in designing and implementing embedded systems used in applications ranging from consumer electronics to industrial automation.
AVR High Voltage Programming (Fuses Rescue) While working on a new prototype for my GPS module for Yaesu VX-8DR/DE transceivers, I made some newbie errors burning incorrect fuses into ATmega328P microcontrollers and bricked them. After some research I found MightyOhm’s High Voltage Programmer which could bring them back to life. His programmer was designed as …
In my previous article about an SPI Flash and I2C EEPROM programmer built with an Arduino, the very first question/comment after publication was “Does it program PICs?” This question, of course, came from an inattentive reader, but it confirmed once again that although PIC microcontrollers are quite old, they still enjoy considerable interest among hobbyists, …
I’d like to share my latest project — a USB programmer for AT89Cx051/AT89C5x microcontrollers, built on what is probably the most well-known and inexpensive development board out there: the Arduino Nano. The programmer’s circuit is fairly simple. Besides the Arduino board itself, it contains a couple of transistors, a diode, several resistors and capacitors, a …

EEPROM programmer Introduction. On this page you are offered the EEPROM programmer “Chameleon”. The programmer allows programming memory chips that have a serial interface. The main difference of this programmer from the majority of similar programmers is that PROGRAMMING ALGORITHMS ARE COMPLETELY DEFINED BY EXTERNAL PROGRAM MODULES. To write a module, you only need …
USBASP Installation in Windows 10 About: Shares instructables for me in case I forgot and anyone interested in my work. More About GandaU » For ATMEGA beginner user, installation of USB-ASP in Windows 10 can be tiresome. USBASP Device is inteded to work with 32 bits yet our current PC Windows 10 is mostly 64 bit. …
Sometimes, when developing devices on 8- and 14-pin AVR microcontrollers, it is necessary to use the Reset pin as an input/output line. This can be done by setting the appropriate Fuse-bit configuration. But after these actions, access to the microcontroller for in-circuit programming is lost, because we disable the Reset line. We will consider a …

USB programmer for beginners Now we will assemble a USB programmer for beginners (beginner radio amateurs), most will say this is a complex circuit, let’s start with LPT, but I want to say that the circuit is very simple, and you only need to program it once and don’t worry. Programmer circuit diagram As …
change fuses for external oscillator I bought five microcontrollers ( MC ) ATtiny2313-20pu from the Chinese (serious guys, I often buy from them) . I turn on AVRDUDE_PROG , connect USBASP Programmer with a breadboard (reliable and tested a hundred times), I upload the firmware and here you go, an error, the Stone is not detected. At first I was …
Programmer PIC AVR eeprom I made a programmer for AVR, PIC and EEPROM, I don’t use it now, but nevertheless, the design can be said to be a must have – simple and works from a COM port. The diagram was in the Radio magazine and on Radiokot, slightly modified. I have a few more …
USB Pic Programmer This post is dedicated to anyone who wants to program a PIC (microchip) device via USB. While browsing the web for ready-to-use projects, I found a nice project called Open Programmer, which has several schematics, PCBs, and open source code. Source link: http://openprog.altervista.org/OP_ita.html. What bothered me was the need to install a …
