☂︎ Low latency event handling
☂︎ Tickless kernel: wake from sleep with micro-second accuracy
☂︎ Static tasks with infinite synchronisation objects
☂︎ Use with Arduino projects to provide multitasking
☂︎ UART low latency API that never drops data
☂︎ UART, SPI, I2C, I2S, GPIO, sensors, robotics
☂︎ ARM support for Cortex-M microcontrollers
☂︎ Easy to configure and expand
☂︎ Posix compliant printf
Tasks waiting for an event are activated as soon as the condition to continue is met.
The UART API is hybrid blocking, meaning that data is queued to send and the call
returns immediately so long as buffer space is available, but will block when the
buffer is full. Receive calls return as soon as any data is available.
