PSoC™ 5, 3 & 1 Forum Discussions

I'm a beginner using PSOC 3 to complete a project for my masters. I've been trying to use to the Uart_PutArray function to transmit an Array to the PC using Uart.

here's some code I've used to simulate an application segment

#include <project.h>
#include <stdio.h>
#include <stdlib.h>

uint8 count[256];
uint8 channel;
int i,x,j;

int main()
{
    CyGlobalIntEnable; /* Enable global interrupts. */
    init();
   
   
    for(j=0;J<10000;j++)
    {
       channel=rand()%255;
       //UART_1_PutChar(channel);
       x=count[channel]+1;
    
       if(x>=0&&x<255)
       {
       
        //x=count[channel]+1;
        count[channel]++;
        //UART_1_PutChar(x);
        //UART_1_PutChar(0x0A);
        //CyDelay(200);
      
         }
       else
        break;
    }

        UART_1_PutArray(const uint8 count[],uint8 256);

}

    void init()
     {
        UART_1_Start();
        for(i=0;i<=255;i++)
        {
            count=0;
         }
        
       }

Hello everyone,

I have the following issue,

I am using a mixer in order to rectify the sine signal. But, the output is not rectified. In fact, it is just flipping (or just changing polarity).

I have the following configuration:

Mixer Input frequency: 50Khz

Mixer local oscillator input (LO): 50Khz coming from PWM.

Reference : Vdda/2 

Both signals are in phase, components are started correctly.

I don't really understand where the error lies.

Looking forward for your suggestions.

Regards

Awais

 An awaited and awesome appnote is here!

Enjoy the power of the PSoC! 🙂

Hello.

I am attempting to utilize the PSoC 5LP device family in a series of projects, one of which requires operation near a magnetic field (there's a reed switch nearby) and I was wondering if Cypress offered any design review services for this as well as for a few other projects. I have experience designing PCBs, but nothing that requires a significant level of detail (fine pitch parts and mixed signal designs), and instead of trying and failing a few times as I like to do, I'd rather invest the time and money upfront to get some experience.

Please note that I utilize both KiCAD and Eagle as the company I work for does not manufacture many electronics products and therefore the purchase of more elaborate, feature rich softwares such as PADS, Altium, or Allegro are not accessible to myself. Also, I have already developed the firmware for almost all of these projects I have, utilizing the CY8CKIT-059.

Thanks in advance,

Adam

Hi.

I had similar problems a number of times already with different projects.

Right now my problem is:

I have a design for a BLDC motor controller, which works without problems. Now I'm trying to add UART component. Actually, I'm not even adding it, I'm re-enabling it, because I've already used it before in this design.

There is no physical connection between this UART and any other component in the design (it's only connected to TX pin, RX pin, and an ISR), but after I add it, something happens and the design becomes unusable. Either state machine of the motor controller is altered, or the PWMs are somehow changed, but it just doesn't work anymore.

What does "help" is disconnecting the TX pin from the component, but then I can't use the UART... Tried to use a different pin for TX - didn't help.

The stupid thing is that I've already used this UART before in the design. Same UART, same pins. Just disabled it at some point and now try to use it again.

As I've already said, it's not the first time I have a similar problem with various designs. But in this design I don't know how to work this around, because the UART is stand alone and is not connected to anything else.

Please help!
