In reply to Anagha. You are going to have to give me more information... what is happening?

Hi Alan,

I tried all the steps that you have mentioned in the above article on CY8CKIT-044 PSoc4 , but some how my freeRTOS port seems to be incorrect . My LED is not blinking . I tried the regular UART code without FreeRTOS , it worked perfectly well. However, the same code when written using FreeRTOS did not work. If possible can you help in this ?

In reply to Taimoor Naveed. On PSoC6 we added a callback that is called when the event loop needs to be called. You can see in some/most of the P6 examples I give a semaphore from ISR in the callback. We have not yet added this to PSoC4BLE.. but I for sure want to. Cypress is committed to RTOS support everywhere and I have been driving people to add this mechanism to many places... e.g. CapSense so that you dont have to poll it.

Hello,
Thank you for this awesome tutorial. Works like a charm.
Not sure if this is the right place to ask this question, but I don’t know where you post this.

I am working with PSOC 4 BLE and I’ve created a task that calls CyBle_ProcessEvents() in a loop. As i don’t want this task to run all the time (only when there in an event throught ble), I wan’t to block this thread using a semaphore or a queue. The problem is that I don’t know where to give that semaphore or add data to the queue when I want to wake this task. Normally, you do this kind of stuff in an ISR, but in this case i can’t find the ISR for BLESS

In reply to Leslie Mills.

It will for sure work. Yes there are a few small things that you need to change for the CM3.

I haven’t personally tried it… but I know that people have.

Did you figure it out?

Alan

Hello, I am trying to follow these steps to port it to a PSOC 5LP (CY8C5888LT*-LP097) prototyping kit, and I am having some issues with build errors with the file includes. Would this work for the the M3 chip? I did make some modifications which I will list below, but then everything else was followed to the letter.

“FreeRTOS/Source/portable/GCC/ARM_CM0” WAS CHANGED TO “FreeRTOS/Source/portable/GCC/ARM_CM3”

In reply to AKSHAY SATPUTE. That function was at the top of the file and all it does is hook up the interrupt vectors for the FreeRTOS

Hello Sir
I have one doubt.
Where should I write “setupFreeRTOS” function ? Is it need to write in main.c ? Or some other C files?

In reply to Scott Yanke. You are welcome. Figuring out the right stack size is something that I always wish that i had a better answer for.

This seems to work quite well. Thank you for the example and pointing me toward the sources. A couple of notes – With a heap size of 10240 it is too large for a PSOC 4200, I had to reduce that down to about 2000 because the chip in the CY8CKIT-049-4200 only has 4k of RAM. It’s ok for the 4200M with 16k of RAM on the chip for the CY8CKIT-043 board. The part of the code that blinks the LED, RED_Write(~RED_Read());, was not understood during compilation, so I changed that to using a control register, Control_Reg_1_Write(~Control_Reg_1_Read());. It gave me a chance to understand the control register a bit better. Other than that, it was fairly simple and easy to setup and test. Thanks again!

In reply to Hassane. Nice! ... Always count on PSoC!
