Hi,

I'm just rebuild the sample project CE58352. It's a FIR Filter 8 - Bit. I think i can transfer the values form the AD converter to the filter, but i don't get a DMA request from the Filter_1 to the VDAC. I tried to debug the project with the UART interface and the code never gets a Status_Reg_2_Read() == true.

I think there is a problem with the DMA configuration. I'm the DMA configuration with the DMA wizzard like the description in the cypress document CE58352

Perhapse someone has an idea what i have made wronge.

Have a nice day

Hi,

I would like you to send me the source code of the standard library functions: memcpy() and  memset().

Thanks

PSOC5, SPI Master. I think I am supposed to be clearing the RX Buffer, but it's not empty. Why?

I have a simple project that turns the onboard LED on/off via the switch.

Then reads the state and outputs "Light On" or "Light Off" via usb uart using _PutString function.  The code and the working serial out:

However, when I add a second consecutive line with the _PutString function, the output garbles badly and ultimately fails to respond after 13 or so button presses.

I'm expecting a "Line2" to get printed underneath "Light On".

I am using a ILI9341 240x320 LCD Controller configured for Parallel indirect interface with a Touch screen.  I do not know whether to add the nosts or osts directory to the compiler from the Include directory. Also, do not know which file to add to the linker,  libemWin_nosts_cm3_gcc.a or  libemWin_osts_cm3_gcc.a from the GCC directory. I guess this depends on whether I am using RTOS but not sure not sure how to determine whether I am or not. There is the question of which GUI_X  Source file to use, GUI_X.c, GUI_X_FreeRTOS.c, GUI_X_embOS.c or GUI_X_uCOS.c from the FlexColor directory.

Any suggestion, Thanks Mike

Hello All!

Is there a way I can echo simple printf commands inside the IDE for debugging purposes?

With Arduino I use serial.print() religiously to debug programs as I work.   Seeing what's inside variables, creating breakpoints to see if a program has gone awry, etc.

I've tried to replicate that approach with my CY8CKIT-059, but the USB UART serial interface is much more complex.  As I learn it, I'm trying to debug it too (LOL!)

Hi all,

I am currently working on trying to read the RPM of a motor using a PSoC 5LP. The sensor consists of a IR sensor and a disc encoder. The disk encoder has holes that generate a pulse every time it blocks the IR sensor making the sensor output signal a PWM So far I was able to read the speed of the frequency/RPM of the motor doing the following:

Code:

#include "project.h"

char string[120];

int count;

CY_ISR(Counter_ISR){

    count = 5*Counter_1_ReadCounter();

}

void Init_Hardware(void){

    UART_1_Start();

    PWM_1_Start();

    PWM_2_Start();

    Counter_1_Start();

    ISR_Counter_Start();

    ISR_Counter_StartEx(Counter_ISR);

}

int main(void)

{

    CyGlobalIntEnable; /* Enable global interrupts. */

    Init_Hardware();

    for(;;)

    {  

        sprintf(string,"%d Hz\n \r", count);

        UART_1_PutString(string);

    }

}

The way it works is that the PWM sets a window during which the counter will count an event.  The ISR component is used to read the count every time the interrupt event happens within the PWM block. The other PWM is just there to drive the motor.

My problem is that the counter variable does not seem to update should the speed change.

Any help will be appreciated.

Thanks

P.S I do not know how to properly attach a project to posts.
