PSoC™ 4 Forum Discussions

I'm trying to spin up on PSoC (have been doing AVR), but I can't assign a  pin to P6[5], which is wired to the blue LED ("P6 cannot be used for routed connections"). Yet the sample project Touch Gestures has a pin attached to P6[5]. I can't see anything different in the configuration of the pin (e.g. Transparent mode). What do I need to do?

how is the re-connection time reduced ?

The requirement is the following

1:  PIN_0 connect to external chip, it will trigger when recv something.

2:  PIN_0 will connect to the capture of UDB timer

3:  Interrupt is connect to a ISR, and trigger when capture=1

With the following code, but never get a interruption.

Timer_1_Start();

CyGlobalIntEnable;

Timer_1_StartEx(My_Interrupt);

Any suggestion on UDB Timer with GPIO?

Hello colleagues,

I am trying to measure AC current with your PRoC (Eval Kit) and the Allegro's ACS712 but I can just measure noise. I am using the ADC SAR Block with 4.8Vdc as reference and very fast sampling (125ksamples per second). The ADC SAR block screenshots are attached and below is the code:

CY_ISR(ADC_SAR_SEQ_ISR)
{
    
    if (count == 0)
    {
        min=4096;
        max=0;
    }

    readValue = ADC_SAR_SEQ_GetResult16(0);    // Channel 0 is connected my pin to the ACS712 output
    
    if (readValue > max)
        max = readValue;
    if (readValue < min)
        min = readValue;
    count++;
    
    if (count >= 25000) // 0.2 seconds
    {

        mamp = 2.5*(max-min); // (1000*0.353*4800)/(4095*166)=2.5   // 1000 is A to mA, 0.353 is from Vpp to Vrms, 4800mV is Vref, 4095 are the bits of resolution and 166 is the mV/A given by my ACS712 
        count=0;
    }
        
}

The root problem is that Max and min values are always almost the same (0x5D and 0x5B), no matter which load (no load, 30mA, 200mA or 350mA) is connected. I think the ADC SAR is not really sampling so fast and that's why I measuring always the same, does any of you have an idea of what can be happening?

Thanks in advance,

Peter

I'm a psoc beginner and I'm trying to set an interrupt on FIFO is not empty.

I'm recieving a RS-485 serial stream from an external board that sends data every 3 seconds or so. The signal is low between data update. I have confirmed that I am receiving the information correctly.

The problem I'm faced with is the interrupt being continuously fired. I believe this is due to the RX FIFO accepting NULL between data being sent from the external board, which means the RX FIFO is always not empty.

Is this proper behavior for the SCB UART? Is there a way to ignore incoming NULL characters? I expected it to be blocking until a non NULL character was received.

I tried to search the forums but didn't find what I was looking for. First time posting, Any help would be hugely appreciated!

Thanks!
