PSoC™ 5, 3 & 1 Forum Discussions

 I want to interface PSoC 5 with CC2500  for doing a project. I have output from the Rx pin of cc2500 (TTL). How do I get the data to PSoC 5? 

Hi at all,

I'm working on PSoC5LP and I'm facing with a problem; I'm trying to get an interrupt from a global signal, setted on CTW:

This is my very simple main:

==================================================

uint8_t ctw_int_flag = 0u;

int main()
{

    /* Uncomment this line to enable global interrupts. */
    CyGlobalIntEnable;

    GSCTW_int_Start();       
    for(;;)
    {
        if(ctw_int_flag == 1u)
        {
            ctw_int_flag = 0;
            Pin_ctwSig_Write(~Pin_ctwSig_Read());           
        }
        else
        { }
    }
}

==================================================

and in the interrupt routine:

CY_ISR(GSCTW_int_Interrupt)
{
    /*  Place your Interrupt code here. */
    /* `#START GSCTW_int_Interrupt` */
    ctw_int_flag = 1u;
    /* `#END` */
}

Even if it's all very simple, the interrupt doesn't raising and I really do not know why...please, colud anyone help me ?

Regards

 I am beginner in PSOC. I am trying to program CY8CMBR3110 using Miniprog-3 by I2C protocol. In EZ-Click 2.0, when i try to select I2C target on 5v, It can't identify it. but if i select 2.5v or 1.8v, It identify device. So i do't understand what is problem. I attach circuit diagram.

Hello,

in the datasheet of the PSOC5LP in chapter 6.2.1.5 Wakeup Events I found that wakeup events are configurable but I didn't found how. I use hibernate mode and want only one external interrupt as a wakeup source. How can I configure only one out of all external interrupts as a wakeup source?

Or is the solution in AN72382 with the do-while loop the only solution?

As a workaround I switched the other interrupt pins to output, so no other external interrupt can occur.

Thanks for your help.

 I have a PSoC5LP Project which has been around for years.

This week I installed the latest PSoC Creator 3.1 Update, and now my system won't fully.

It is more or less operating normally, with the exception that every malloc() fails.

It's as though the system has suddenly ran out of RAM.

It is a very large project, but there is not actually a huge amount in RAM, and anway, it was working fine before I updated to Creatpr 3.1 and re-compiled everything.

At the end of compilation I get this message:

Flash used: 110520 of 262144 bytes (42.2 %). Bootloader: 16128 bytes. Application: 94392 bytes
SRAM used: 28453 of 65536 bytes (43.4 %). Stack: 2048 bytes. Heap: 128 bytes.

 Hi,

is there a simple way to detect, if an interrupt occurs during a specified time. I only need to know if something happened. Within this time there is a time critical procedure. I have to drop the results, if there was an ISR call between processing. But I can not disable global ISR within this time.

Sure, I can use flags inside each ISR. But this is something dificult to do inside the cypress modules (USB_FS e.g.).

So maybe I could check a register?

Kindly regards,

Franz
