It is designed to be multi-architecture, portable, and easy to use within the open source community universe. -We have chosen PlatformIO and Arduino as our official deployment platforms. The library has been supported and tested on general **AVR boards (ATmega168/328, ATmega16u4/32u4, and ATmega2560)** as well as **ARM boards (Teensy, STM32XX, and Seedstudio XIAO M0)**. It has experimental support for **RP2040 boards (Raspberry Pico, Seeed XIAO RP2040)** (see notes). +We have chosen PlatformIO and Arduino as our official deployment platforms.

The absence of real-time features necessary for creating professional-level embedded devices for music and video on open source community-based platforms like Arduino led to the development of uClock. By leveraging the use of timer hardware interruptions, the library can schedule and manage real-time-like processing with safe shared resource access through its API. @@ -370,13 +370,4 @@ void loop() //processYourLeds(); //processYourPots(); } -``` - -## Known problems - -### RP2040 support - -- Uses the [earlephilhower core](https://github.com/earlephilhower/arduino-pico) -- Doing a 'soft reboot' (eg from reflashing) seems to crash on startup, but starting from cold and powering on works fine. -- Using FreeRTOS multithreading fails if the second core is used (via setup1() and loop1()) - using the 'interrupts-based' version of the RP2040 uClock support seems to solve this. -- Tick ticking may be off due to repeating_timer following from the end of previous tick, rather than following the start of the previous tick. +``` \ No newline at end of file
