This repository provides a ready-to-use template for quickly working with the peripherals of the LandTiger development board based on the ARM Cortex-M3 (LPC1768). It includes modular drivers, practical examples, and an organized structure for embedded projects.

Open-hardware 32-channel EEG/BCI acquisition board — quad TI ADS1299 AFE + ARM Cortex-M3 (ATSAM3U4EA-AU), Altium source, 2015. ARM sibling to Adam-EEG.

Bare-metal STM32F1 firmware built from scratch with CMSIS and Makefile. Includes register-level drivers for GPIO, UART, ADC, Timers, and SysTick — featuring custom linker scripts, startup code, and GDB/OpenOCD workflow.

Working on STM32F103C8T8 (Blue Pill) using the STM32 HAL library driver, but without code generation from STM32CubeMX. The project supports building (CMake) and debugging (Cortex-Debug) on Visual Studio Code.

RA3 RTOS is an open-source real-time operating system designed for embedded systems, currently supporting ARM Cortex-M3 processors. It features efficient task management, preemptive priority-based scheduling, and inter-task communication mechanisms (semaphores, mutexes, event groups) optimized for memory-constrained environments.
