PSoC 4 port & demo project

I've ported FreeRTOS to PSoC 4 - which really was extremely trivial. It's simply the Cortex M0 port with some configuration & glue from the PSoC 5 demo.

The attached demo app creates three tasks that toggle the red, green and blue LEDs on the PSoC 4 pioneer board at slightly different rates, resulting in a pleasing (if somewhat psychedelic) light show. Adapting this demo for your own purposes should be straightforward.

Note that because the PSoC Capsense component makes (undocumented) use of the systick timer, it's not currently possible to use FreeRTOS and the PSoC Capsense component together.

  Correction: Capsense does not use SysTick; the issue was an unrelated interrupt problem.

  Awesome Job Nick!,  

  I, for one, am interested in giving it a try.  Does this mean the Capsense is now working, or still no-go, just for a different reason?

  Best Regards.

  Capsense should work fine - just be sure to enable global interrupts before calling CapSense_Start().

  Hi,

  I have posted this question in one of the other threads but thought I would get a faster response if I repeat it here.

  Is it possible to port this FreeRTOS to the PSoC 4 prototyping kit? It has the same MCU CY8C4245AXI-483... 

  If yes, what are the changes that I need to make?

  If no, is there a separate version of FreeRTOS for the prototyping kit? Please provide me one in that case.

  Thanks in advance and regards,

  Shreesha

  Hello,

   

  Will this work with the PSoC4 BLE Kit?

  I will get this up and running on the Dev Kit anyway and then try to enable each of the BLE Modules.
