• Kernel routines are provided by a library that is automatically included by the linker. All you must do is

specify the RTX166TNY directive.

• Interrupts may be used to trigger tasks or to start standard C166 interrupt functions.

• RTX166 Tiny supports all C166 Compiler memory models.

ARTX-166

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. 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 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.

Features

For a comprehensive list of features refer to the C166 RTOS Comparison Table. Here are the highlights:

Kernel

• 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

• Stores data in binary, ASCII, or any other format.

• Flash file system applications are written using standard C constructs.

• 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 Networking

• 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.
