Restoring the Fuse-bits configuration of ATtiny13, ATtiny25/45/85 (HVSP)

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

Microcontrollers Projects, Programmers

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

Microcontrollers Projects, Programmers

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 for PIC, AVR and eeprom

Microcontrollers Projects, Programmers

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

Programmers

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 …
