PSoC™ 4 Forum Discussions

Hello,

We have been using PSOC ble custom profile to collect around 40 bytes of sensor data from micropython board using UART with psoc ble. We are sending the data using the psoc BLE to Cysmart windows app. However when we power the psoc with the usb cable we can receive the updated streaming data but not when batterey powered. We can only read data once when we batterey power it. Can you please help us resolve this problem.

Further we used ASUS dongle in raspberry pi and raspbian OS to receive the BLE data. We can receive not more than 20 bytes of data on raspberry pi. If the MTU is more than 23 bytes we cannot receive the data. However we can receive as much as 512 bytes on Cysmart. We tried to search for the reason and solution for it but we couldnot find any. Can you explain us about the situation we are facing?

Thanks in advance.

I cannot seem to find an example for serial in parallel out conversion. this is with respect to the prototyping kit platform. Any help is appreciated

Hello all,

Greetings for the day.

      I am trying to configure a 4x4 Matrix Keypad using PSoC Creator 3.2 with the help of PSoC 4 Pioneer kit (i. e. mentioned to ACK device used).

While doing that I have done some part, just wanted if I am on right track or not.

As of yet my test board with 4x4 Matrix Keys implemented hasn't arrived, I'm unable to check it's o/p to verify the program. That's why I wanted to check whether I'm going ok or not.

I'm attaching my project down here, please go through it & let me know my status; guide me if I'm going wrong.

If anyone have 4x4 board to test it, please do that & convey the results.

Waiting for your positive response & valuable guidance.

Thanks & Regards-

Amit

First post here,

     We're trying to locate the SCB_Bootloader.cywrk project which is located on page 19 of the PSoC 4 Prototyping Kit Guide, Doc. #: 001-90711 Rev. *G. The project uses the PC's USB as a comm ports for downloading code and is also nice enough to flash a led.

The problem is that PSoC Creater does not have this example listed and I can not find it on Cypress's web site. There are other boot-loaders examples for the PSoC 4, but they use the I2C. Were just trying to get the basics down of this kit and would appreciate any help.

Thanks,

Our company uses SVN system and everybody checks project out to different directory. I need to add relative path to Build Settings-> Compiler->General->Additional Include Directories in PSoC Creator. . What should  its format be?. I m giving example of IAR Workbench.
"$PROJ_DIR$\..\..\folder name\foldername" this format is IAR relative path directory ,how can I do same thing for PSoC Creator.

When I run CE95401(I modified a little) code example in  PSoC 4 Pioneer Kit in debugging mode. I put breakpoint to firstline of main. when the device recieves reset , it should return first line again but it doesn't and goes an unknown state . I also put breakpoint to isr_wdt interrupt service routine , it doesnt stop there after recieve wdt reset.                        
However if I just toggle LED in first line of main and  program(not debug) kit works what it is supposed to work 
 I m asking why the reset doesn't work properly in debugging mode?
I  attached my code and Call Stack photo of unknown state
 

I used PSoC  Creator 3.1

Attached is an image of Table 5. Power Modes System Status from the CYBL10X6X Family Datasheet.

Do I take this to mean that I can not wake up from Deep Sleep every 25ms by the ISR of a timer driven by an LFCLK clock whose source is WCO clk because no code is running in deep sleep?

Here is my code attempt:

CY_ISR(Timer25ms){

    Timer_25ms_ReadStatusRegister(); //clears interrupt, found this in component datasheet

    if (flop % 128==0)RED_Write(!RED_Read());

    godeepsleep=1;

    flop++;

}

Main loop is:

    while(1){
        if (godeepsleep==1){
            CySysClkEcoStop();    
            CySysPmDeepSleep();
            CySysClkEcoStart(0);    

            godeepsleep=0;
        }
    }

The code executes and flashes LED fine in debug mode (probably can't go to deep sleep in debug or something) but the device goes to deep sleep and never wakes up on its own powered by battery (shows current of 1ua so I know it goes to deep sleep).
