LED1, LED2 and LED3 are under control of the 'flash' tasks.Not all the LEDs are present on the EVK1101): When executing correctly (without the 'check' task having detecting any errors) the demo application will behave as follows (note that LED assignments areĬorrect for the EVK1100. In addition the 'check' task exercises the memoryĪllocator by repeatedly allocated and freeing blocks of memory. Its function is toĬheck that all the other tasks are still operational and that no errors haveīeen detected at any time. High priority so is guaranteed to get processor time. The check task only executes every three seconds but has a In addition to a subset of the standard demo application tasks, main.c also More information on the standard demo tasks. Main() simply sets up the hardware, creates all the demo application tasks,ĭemo Application section of the FreeRTOS website provides The demo application makes use of the LEDs that are built onto the EVK1100 / EVK1101 so no further hardware setup is required. For correct operation of this functionality a loopback connector must be fitted to the UART_0 connector of the EVK1100 or USART1 of the EVK1101ĭevelopment board (pins 2 and 3 must be connected together on the 9Way connector). The demo application includes an interrupt driven UART test where one task transmits characters that are then received byĪnother task. Located in the FreeRTOS/Demo/AVR32_UC3/AT32UC3A/IAR directory. The AT32UC3A demo project file for the IAR tools is called RTOSDemo.eww and can be The AT32UC3B demo makefile for the GCC tools can be located in the FreeRTOS/Demo/AVR32_UC3/AT32UC3B/GCC directory. The AT32UC3A demo makefile for the GCC tools can be located in the FreeRTOS/Demo/AVR32_UC3/AT32UC3A/GCC directory.

Lwip loopback cable download#
The FreeRTOS download contains the source code for all the FreeRTOS ports so contains many more files than used by this demo. Information on the TCP/IP demo can be found at the bottom of this page. This section described the standard demo application. See also the FAQ My application does not run, what could be wrong? IMPORTANT! Notes on using the Atmel AVR32 port Please read all the following points before using this RTOS port. There is also a separate port under development for the AVR32 AP7000 series. Thanks to the Atmel engineers for their large contribution in the development of this port! The demo application was developed on and targeted at the EVK1100 andĮVK1101 evaluation boards for the AVR32UC3A and AVR32UC3B demos respectively ( instructions are provided should you wish to use an alternative development board). The TCP/IP demo uses the lwIP TCP/IP stack and includes a basic web and TFTP server implementation. For the UC3A port an embedded TCP/IP example is also provided. IAR (V2.21A or higher required) development tools. Instructions are provided for building the standard demo application with both the AVR32 GCC and This page presents the FreeRTOS AVR32 UC3A and UC3B ports and demo application for the AVR32 AT32UC3 range of microcontrollers.
