Picolibc is a C library designed for embedded environments. Providing a complete C17 library interface along with much of the POSIX 2008 additions, Picolibc offers standards conformance, broad architecture support and integrated testing performed under emulation on the target architectures. This talk will start by providing an overview of Picolibc, including API support, standards conformance and memory usage. Then, a description of the testing infrastructure, including the bare-metal test frameworks, emulator bugs fixed and guidance on supporting new targets will be provided. Next, some specific examples of integrating Picolibc into various embedded RTOSes, including FreeRTOS, Zephyr and RIOT will be presented. The talk will finish with the current status of Picolibc along with future plans.
