BeRTOSis areal-time operating systemdesigned forembedded systems.

It isfree and open-source softwarereleased under theGNU General Public License, version 2(GPLv2) or later, with a special exception granting proprietary applications the right to keep their source code closed while keeping the base BeRTOS code open.

It has a very modular design, that allows running it on different architectures, ranging from tiny8-bitmicrocontrollerssuch as AtmelAVR microcontrollersup to the32-bitARM architecture,and on hosted environments such asLinuxandMicrosoft Windows.BeRTOS is written inANSI C,and supported by popular embedded Secure Sockets Layer (SSL) and successorTransport Layer Security(TLS)librariessuch aswolfSSL.

BeRTOSpreemptive multitaskingkernelimplements manyinter-process communication(IPC) primitives, including:signals,semaphores,andmessages.

In addition to the kernel, BeRTOS provides ahardware abstraction layer(HAL) that includes many peripheraldevice drivers(timer, serial,analog-to-digital converter(ADC), motors,liquid-crystal display(LCD), NTC sensors, keyboard, buzzer, memories), algorithms (hash table,cyclic redundancy check(CRC),MD2,entropy pool,run-length encoding(RLE)), communication protocols, and a graphic windowing subsystem for smalldisplay devices.
