PSoC™ 5, 3 & 1 Forum Discussions

 Till now I bitbashed the SPI. I would like to use the component but cannot see how you can read back bytes at same time as sending (in my bit-bashed code I return the received character). Here is my code. Would somone mind advising me how to set this up better. 

#include <project.h>

#define CONFIG_REG 0x01

uint8    RX_Buf[20];

uint8    RX_Bytes;

uint8    TX_Buf[20];

void SPI_Write(uint8 * buf, uint8 n){

    uint8 i;

    for(i=0;i<n;i++){

      SPIM_WriteTxData(buf);

      while(!(SPIM_ReadStatus() & SPIM_STS_TX_FIFO_EMPTY));

    }

}

uint8 SPI_Read(uint8 adr,uint8 n, uint8 * buf){

    uint8 i;

  SPIM_WriteTxData(adr); //Register address

while(!(SPIM_ReadStatus() & SPIM_STS_TX_FIFO_EMPTY)){};

    for(i=0;i<n;i++){

        SPIM_WriteTxData(0xff); //write dummy byte

while(!(SPIM_ReadStatus() & SPIM_STS_RX_FIFO_NOT_EMPTY)){};

      CyDelay(1);

 buf= SPIM_ReadRxData();

    }

return i;

}

int main()

{

    CyGlobalIntEnable; 

    SPIM_Start();

    for(;;)

    {

      RX_Bytes = SPI_Read(CONFIG_REG,1,RX_Buf);  //read 1 byte from Config Register and place in RX Buffer

      TX_Buf[0] = 'A';

      TX_Buf[1] = 'B';

      TX_Buf[2] = 'C';

      SPI_Write(TX_Buf,3);  //Write 3 bytes of TX buffer to SPI

      CyDelay(100);

    }

}

I am now back home from a visit to Cypress at the embedded world in Nuremberg hving talked to many of the Cypress engineers and having seen the new devices Cypress is going to release.

In my opinion the most remarkable news is a PSoC5 Prototyping Kit that, differently to the PSoC4 version, allows for debugging!!!

Second in list, not in value, is a re-designed Pioneer Kit which has got an external F-Ram on-board that is interfaced like an eeprom, but is quite more reliable and nearly immune against power losses during write-accesses, see a video here. I was able to see at the Cypress booth that there is no fake with the F-Ram, so no additional pre-cautions are needed to bypass the power-loss problem when an eeprom-write is started.

Cypress announced some larger PSoC4 BLE chips for the next quater

And lastly: I had a (very) small glimpse ar a Creator 3.2 Beta on one of the PCs, so stay tuned for the new announcements when all of those "secrets" get official.

Happy coding

I have a project where I'm using the DMA to access memory in RAM. The whole problem is that I need to specify the base address of a 2D array, so for example how do I specify the starting address for:

uint8 frame[2][19200];

 I found there are two CPSD0 and CPSD1 block in creator3.1/analog tab for cy8c3865axi-204.

so i want to use one of these cpsdx to implement touch-key. but when i add capasense-csd component in project, i found the component need a comparator, but this device doesn't have comparametor.

So, is there at least one error built in capasense component that it doesn't release attribute which is set by default to true for autoenable in Vref component?

or, other errors?

As you can see, I got the serial out to work, but not the serial in.  I also tried various configs for the uart, but no luck yet. I  don't need to use interrupts yet, so let's leave that out for now.  Pretty simple. . . use crlf to store the string, check the string (future code) for valid stuff, and then do whatever.  More pressing instrumentation problems are awaiting me. Thanks for any help.

Never sent a bundled file. Hope it works.
