EXIRION/OS

EXIRION/OS is an operating system for embedded computer systems. These operating systems are designed to be compact, efficient at resource usage, and reliable, forsaking many functions that non-embedded computer operating systems provide, and which may not be used by the specialized applications they run. They are frequently also referred to as real-time operating systems, and the term RTOS is often used as a synonym for embedded operating system. EXIRION/OS project, a Open operating system for computers that can be used in specific operations that require execute a task at a time, EXIRION/OS operating system is a monolithic and mono layered task, which can be used to control complex electronic equipment without the use of instruments PLC, offering a wide range of electronic and industrial applications, EXIRION/OS is also an educational tool, it is an open source operating system to use it as an example of building operating systems in universities and technical colleges.

STM32-Development-Board-for-Teaching

While studying B Tech 8051 is the controller used in the course syllabus. While 8051 is very fundamental and helpful to understand the basics, it is quite old and not always industry relevant. It's said to learn something, the best way is to make it. After a lot of exploring I decided what better way to learn ARM is to make a development board. This would expose us to most of the interfaces of the controller while also providing us with exposure to essential skills like schematic design, PCB manufacturing and SMD soldering. There are a lot of development and evaluation boards but they were not aimed to supplement the uC course at bachelor level, where the students are beginners with none to little experience. My intention with this board something with separate breakouts for various interfaces like I2C, SPI and also peripherals using those.
