Learn to port TobudOS system to AT32A403 development board.

1. Introduction to TobudOS

TobudOS is a real-time operating system developed for the Internet of Things field. It is based on Tencent's self-developed Internet of Things operating system TencentOS Tiny open source project. In 2020, Tencent donated it to the Open Atom Open Source Foundation for incubation. In 2023, it was officially renamed TobudOS. TobudOS has the characteristics of low power consumption, low resource usage, modularization, security and reliability, which can effectively improve the efficiency of IoT terminal product development, provide a streamlined RTOS kernel, and the kernel components can be cut and configured, which can be quickly ported to a variety of mainstream MCUs (such as the full range of STM32) and module chips. Moreover, based on the RTOS kernel, it provides a wealth of IoT components, and integrates mainstream IoT protocol stacks (such as CoAP/MQTT/TLS/DTLS/LoRaWAN/NB-IoT, etc.), which can help IoT terminal devices and services quickly access the IoT cloud platform.
