PSoC™ 5, 3 & 1 Forum Discussions

I am thinking about writing blog articles highlighting the PSOC 5.    These articles would be beginner to intermediate, and reflect what I've struggled with and learned.

I would like to hear suggestions on how or where to do this.  It would be nice if I could submit to an existing system.    I expect to write something about every 2 weeks or so. I use a Mac, so it would be centered around using Virtual Machines, and tricks and techniques when using things like a Mac.

Topics would be general software design principles, A/D, D/A, EEPROM, FreeRTOS, designing with FreeRTOS, using the USB with Mac (and sometimes windows), etc.  Also, using with external processors such as the ESP32-WROOM, etc. 

The example hardware will be the CY8CKit-059, so it will be inexpensive for someone to use and follow along.

At the beginning, I am not looking for compensation, so that is not a concern.  (I won't reject compensation, but it is not my primary goal.)

This will be a first in the blog arena.  I have published a computer book, and have written articles for magazines in the past, so I understand what I am signing up for.

  comments anyone?  (Even negative comments are welcome! My skin is thick, and I know I am an idiot. <grin>)

Hello Everyone,

These are some of my early days working with the Psoc 5LP CY8KIT -059 and I come from a mechanical engineering background so please bear with me.

I am using the SAR ADC to measure 0-5V from the terminal of the DC motor and reading this display on the LCD

I chose the single ended input range i.e from Vssa (GND) to Vdda (5.0V)

This arrangement only gives me a reliable reading from >1V - 5V. Any reading below <1V is displayed erroneously

I also tried switching input range from 0 to Vref*2 ( 0 to 2.048)  but this also did not help.

I am having trouble root causing this and would appreciate any input to help me through !

Thanks in advance.

Hello, is it possible for the DDS24 component for PSoc5LP to produce a frequency sweep sine wave between 1Hz and 80Khz at a rate of 8Khz? perhaps by using external components such as the ADS1256? would it be possible to change the frequency sweep from an Arduino/Teensy input?

Hi all,

I am new to cypress community,I am currently working with CY8Ckit-059 psoc kit. I want to read data from the SD card that contaion "new.txt" file.and according to receive data I want to drive some signal(like LED or any thing through GPIO). I am using somthing like Below code. But I am not able to get any data into buffer. so the lile if (n != 0) is not getting executed... even after I am getting pFile as 1 because this loop  for( i = 0; i < 5; i++ )  is getting executed I can see that.

can anayboday please help regarding this?

#include "project.h"

int main()

FS_FILE * pFile;

FS_Init();

//FS_Mount(0);

pFile = FS_FOpen("new.txt", "r");

int i = 0;

int n=0;

CyGlobalIntEnable;

n=FS_Read(pFile, abBuffer, 1);

Hi,

I am using psoc 5lp 059 kit, in that i am using spi connection with sd card (micro sd card 16 gb, class 4, san disk)

In that I have error -1,

ex:

        int abx = FS_Mount(sdVolName);

        sprintf(cmdnum,"a : %d ",abx);

        UART_2_PutString("\n\r");

        UART_2_PutString(cmdnum);

        UART_2_PutString("\n\r");

abx = -1, and its error of FS_ERRCODE_EOF (End of file reached)

how to resolve this?

Hi Everyone,

I am facing a problem with SPI communication. I am trying to read data from an external ADC (MCP3201), transform it to temperature value and show it in PUTTY terminal using UART. But I always get garbage value. I am using the ADC as SPI slave and PSOC5LP as SPI Master. I don't understand why I am not getting correct values. Can anyone help? Thanks.
