It can use the Open Watcom or Borland development tools see Tools. A version for use with Eclipse is also available. One or more examples for both categories are provided. Large and small memory models are supported. Not all the tasks update an LED so have no visible indication that they are operating correctly.

To write an interrupt service routine that can cause a context switch: The demo application includes an example tiny web server. A simple USB mouse driver implementation is also provided. The principal of the simulated operation is described on the demos documentation page.

The target board can source its power through the same cable.

You must ensure that freettos configured MAC address is unique on the network to which the prototyping board is being connected. It can use the Open Watcom or Borland development tools, for both of which a pre-configured project file is provided. This might not be the same as the originally interrupted task.

Fail Safe File System: It just a C function though and probably nothing to do with the problem you are seeing. The prototyping board should also allow the use of a standard Ethernet cable when connecting point to point, but I have not tested this configuration.


This will take approximately 20 seconds on a relatively fast PC. Thread aware file system Hint: This demo has now been superseded, see the Kintex demo above. The IP addresses used by the web browser computer and the prototyping board must be compatible.

Please read the usage information provided on the linked page! Delivered online or on-site.

These are HID devices communicating with an application program. The demo application runs on the spike simulator in bit mode, and needs the riscv GCC compiler and spike simulator to be installed somewhere for the build to succeed.

Open a web browser on the connected computer. It includes web server demos using both uIP v1.

[RTOS Support] STM32F4 with FreeRTOS and USB HID

All the interrupt service routine does is signal to the EMAC driver via a semaphore that data is available for processing. Therefore a ‘Check’ task is created whose job it is to ensure that no errors have been detected in any of the other standard demo tasks.

A more complete implementation could spawn a new task for each connection, then wait for data to arrive – deleting the task when the connection is closed. The uIP task This task handles all the network processing. Entering the IP address into the web browser obviously use the correct IP address for your system. Any build problems experienced on a Linux host are likely to be the result of a file name having incorrect capitalisation.

This will do the actual ISR processing.

Components Components required to use the HID class: SWI instructions are used by the real time kernel and can therefore not be used by the application code without modification of the RTOS kernel code.

Each receive buffer is bytes, this size is specific to the hardware and must not be altered. The transmitted data can be viewed using any dumb terminal program for example HyperTerminal set to baud, with 8 data bits, no parity, one stop bit and no flow control.
