Some AVR code that I wrote for my ATmega32 based board. Code is in Assembly and C.

Simplest ultrasonic ANTISPY voice recording jammer based on ATTINY13 / ATTINY85/45/25 / ARDUINO with PAM8403 / TPA3116D2 module driving piezo ultrasonic transducers (and optionally AD8933 signal generator)

extremly light uart library for AVR 8 bit microcontrollers

Library for OLED-displays runs on AVR

AVR library for controlling DS18B20 temperature sensors

ATmega328P driver library

Very simple 433MHz (EU/ASIA) 315 MHz (US) RF jammer for keyless cars theft prevention

AVR cheat sheet for the ATmega328p

DIY GPS GSM vehicle tracker based on SIM808 module and ATMEGA328P

ATtiny13 Software UART library.

This is simple GPS vehicle tracker base on SIMCOM SIM7000E/G/A module. Works for GSM/LTE-M networks around the globe

Script collection to build ready to use GCC 13.1.0 cross and/or native toolchains: C and C++ for all, (Fortran, ADA, D and GO for native compiler only). Cross targets: LM32, AVR, Motorola 68000 (m68k), (ARM in develop yet)

OE layer for tools to work with microcontrollers and electronics

the cheapest GPS tracker / GPS locator based on AVR ATTINY2313/4313 or ATMEGA328 (ARDUINO) and SIM800L GSM module
