## Ultibo core

This is the source for the Ultibo core project, a full featured embedded (no OS) development environment for Raspberry Pi written in Free Pascal.

Ultibo core is much more than just another OS example it is a complete platform for creating modern full featured embedded applications which run without any operating system and provides a large number of stable, ready to use features including:

* Support for all models of Raspberry Pi (A/B/A+/B+/2B/3B/3B+/4B/400/Zero/ZeroW/Zero2W) plus QEMU ARM emulation

* Pre-emptive threading

* Full range of locking and synchronization primitives

* Multicore support on Raspberry Pi 2, 3 and 4 with all cores sharing workload

* Thread priority, affinity and migration

* Complete IPv4 stack including TCP, UDP, ICMP and raw sockets as well as DNS and DHCP protocols

* USB support with drivers for Hub, Keyboard, Mouse, Storage, Network, HID, Touch, Gamepad and Joystick

* MMC/SD/SDIO device support including eMMC devices on Raspberry Pi Compute Modules

* Support for GPIO, I2C, SPI, PWM, UART and DMA devices

* Full support for FAT12/16/32, NTFS and CDFS filesystems

* Interrupt and fast interrupt handling

* Hardware exception handling

* Complete RTL with strings, code pages, Unicode, classes, objects and exceptions

* Full Winsock 1.1 and Winsock 2 implementation

* Standard C library support including POSIX threads

* Prebuilt libraries for Freetype2, SQLite, Zlib, Libpng and more included

* Support for many common FPC packages

* Hardware accelerated OpenGL ES and OpenVG graphics and support for the official Pi camera

* Many included extras like HTTP, SMTP, NTP, SysLog, Telnet and Shell

Note that the Raspberry Pi Pico is not supported by Ultibo core as it is based on a microcontroller instead of a microprocessor and is not able to support the features required by Ultibo core.
