MyLibraries

A collection of reusable C/C++ libraries and utilities targeting embedded systems, Linux POSIX environments, and bare-metal microcontrollers.

Repository Structure

BuildServices/

Used to help organise a Makefile-based build system. Contains common flags, shared Makefile rules, and embedded-specific build configurations to keep project Makefiles clean and consistent.

Common/

Generic libraries and base interface classes for embedded systems. Includes drivers and abstractions for:

• File I/O (file_ops)
• ADC (ads111x)
• Sensors (apds9960, BME280)
• Bit manipulation (bitops)
• Argument parsing (arg_parser)

Linux/

Linux POSIX-based interface helpers. Provides wrappers and utilities for working with Linux system calls and POSIX APIs in a portable and reusable manner.

ARM/

Low-level hardware drivers for ARM-based SoCs. Currently includes GPIO support for the Allwinner H3 platform.

stm32/, stm32f103/, stm32f10x_cpp/, stm32f10x_pr0/, stm32f10x_stdperiph_driver/

Support libraries and peripheral drivers for STM32 (ARM Cortex-M) microcontrollers, including both C and C++ interfaces and the standard peripheral driver library.

stm8s/, stm8l/, stm8s_stdperiph_driver/

Support libraries and peripheral drivers for STM8 microcontrollers, including the standard peripheral driver library.

Examples

File I/O (Common/file_ops)

Basic file write and read:

File f("test.txt");

char str[] = "Test string\n";
f.Write(static_cast<void *>(str), sizeof(str));

char rd[sizeof(str)];
f.Seek(0, File::SeekAt::SET);
f.Read(static_cast<void *>(rd), sizeof(rd));

std::cout << "File size: " << f.GetStats().GetSize() << std::endl;
std::cout << "File contents:\n";
std::cout << f;

CSV file parsing:

CSVFile csv("test.csv");
auto csvData = csv.Parse();

for (const auto &line : csvData) {
		for (const auto &value : line) {
			std::visit([](const auto &v) { std::cout << v << " "; }, value.Get());
		}
		std::cout << std::endl;
	}
