PSoC™ 5, 3 & 1 Forum Discussions

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.

Hi,

Here what I use in this project :

• 'PSoC 5LP CY8C5888LT*-LP097' Prototyping kit
• 2Go Micro SD transcend card
• microSD click from Mikroe
• SD Card Formatter and/or Formatter from Windows 10
• UART (named UARTGPS because of my project) communication with Termite 3.4  instead of LCD in the example.
• Default configuration for emFile in TopDesign
• Tried FAT16 and FAT32
• tried with pins 2[3:6] then 12.0 12.4 12.3 12.2

My code compile without error,

But in the end, it just does nothing, and it seems that it doesn't even see the sd card. It only displays a generic name "mmc:0" which is why I changed the SD card name to "UMTS" to be sure it was not working.

Here I link the schematics for my SD card Reader : https://download.mikroe.com/documents/add-on-boards/click/microsd/microsd-click-schematic.pdf

And all the information : https://www.mikroe.com/microsd-click

Intersting fact that might be a lead : I measured voltage with a voltmeter (DC mode) and I couldn't measure anything except for CS pin

Hi,

We would like to use BCP(Bridge Control Panel) with PSoC5LP.

For PSoC4, RegistorMap.h file is generated automatically but PSoC5LP is not.

Therefore, these parameters of the sensor to transmit is unknown.

If it is PSoC4, Component name is CapSense, Sensor name is BUTTON0(Initial name when added),

Raw count : CapSense_BUTTON0_SNS0_RAW0_VALUE

Baseline : CapSense_BUTTON0_SNS0_BSLN0_VALUE

Diff : CapSense_BUTTON0_SNS0_DIFF_VALUE

Signal : CapSense_SNS_STATUS0_VALUE

Where should I refer to PSoC5LP?

I searched for but I did not know the corresponding register.

Regards,
