ARTX-166 is an advanced real-time kernel for the Infineon XC16x and C16x as well as the STMicroelectronics ST10 families of microcontrollers. It is designed to solve several problems in embedded programs:

• Multitasking allows you to manage several jobs (tasks) on a single CPU.
• Real-time Control allows you to configure tasks so that operations execute within a defined period of time. You have control over task priorities, round-robin, preemptive context switching, and support for multiple instances of the same task function.
• Flash File System allows you to create, save, read and modify files stored on a standard Flash memory device.
• TCP/IP Networking is a ground-up implementation specifically designed for embedded applications. It helps you to create TCP/IP solutions that connect to standard internet browsers.

Kernel Features

• Tasks are integrated into the C166 C Compiler language. The following example shows how tasks are declared. void display_task (void) __task
  {
  }
  
• Kernel routines are provided by a library that is automatically included by the linker. All you must do is specify the AR166 linker directive or select Advanced RTX166 within the µVision IDE.
• Interrupts may be used to trigger tasks or to start standard C166 interrupt functions.
• Several methods of inter-task communication are provided including events, mailboxes, and semaphores.
• ARTX-166 supports all C166 Compiler memory models except the Tiny Model.

Flash File System Features

• Stores data in binary, ASCII, or any other format.
• Flash File System applications are written using standard C constructs and are compiled with the Keil C166 C Compiler.
• You may specify numerous configuration parameters including: maximum number of files, file I/O buffer size, and sector layout.
• Code to write and erase flash blocks is easy to configure for each project.

TCP/IP Features

• A TCP/IP Library supports internetworking on C16x, XC16x, and ST10 devices.
• Protocols supported: ARP, UDP, TCP, HTTP, TFTP, SMTP, DHCP, Telnet.
• Pre-configured for Crystal CS8900A and Asix Ax88796 Ethernet Controllers. Other Ethernet controllers may be used with user-configured initialization routines.
• Several example projects are available.
