It provides operating system-like facilities for homebrew applications, and serves as a new foundation for libnds (and DS homebrew in general). Its main features include:\n\n- Multitasking system, providing threads (inspired by Horizon). Scheduling is preemptive and based on multiple priority levels, similar to real-time operating systems.\n- Synchronization primitives: mutex, condition variable, mailbox.\n- Interrupt and timed event handling.\n- Low-level support bits for integration with devkitARM (crt0, linker scripts, syscall implementations).\n- Message passing between the two processors (ARM9 and ARM7).\n- New device drivers for ARM7 peripherals, with programming interfaces accessible from the ARM9:\n\t- Power management, including sleep mode and application lifecycle management\n\t- Touch screen (both DS mode and DSi mode)\n\t- Real-time clock\n\t- Audio and microphone\n\t- Storage devices, including DLDI and DSi SD/eMMC\n\t- Wireless communications (Mitsumi/NDS and Atheros/DSi)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdevkitpro%2Fcalico","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdevkitpro%2Fcalico","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdevkitpro%2Fcalico/lists"}
