Ultibo Core

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.
