PSoC™ 4 Forum Discussions

Hi,

is it possible to wire the PSoC4BLE in a way, that the fixed Timer/Counters are running with LFCLK?

Background: I need a (really) low power timer running at 4096Hz with a compare unit which is interrupt capable.

My current efforts are always stuck, because PSoC Creator is telling me, that I have to use HFCLK as clock source, actually: "The component requires a clock from the clock block." So the question could be transformed to "how to put LFCLK into the clock block?"

Thanks

Hardy

Hello

I have  Psoc 4  KIt.  recentally I have done LED, LCD based  Project. Now I want to interface ds1307 with LCD. I looked  example project. That’s based on Psoc 3. But I am using Psoc 4

 I created design.  Design consist of LCD and ds1307. I am attaching my project workspace. please inform me there is any mistake in design 

I am having problem in programming. I saw program in example project. That program was  written for Psoc 3.

In my design, the battery (the capacity is 50mAh) is always feed into the the pSoC4 BLE.

When an user touch the device, the pSoC4 BLE should power on the system(other chips etc.). 

The  pSoC 4 BLE's capsense is periodically(1sec via WDT) check the user's touch. 

The Capsense Low Power Method is shown on page 64  http://www.cypress.com/?docID=50746 . 

In this low power design, What is the current consumption ? 

In my case, It must be needed under 5 uA.  

 Hi all, I just purchased a Pioneer Kit, and started testing basic connection between the PSoC4 BLE and my laptop and phone.

The connection with the usb dongle was fine, and i could use the CapSense Slider of the board to see how the dongle's blue led glows and fade.

But when i try to connect the PSoC with my android phone, i cannot stablish a connection.

If I use the Android native bluetooth settings, i can see the PSoC as "BLE Slider and LED", but the connection get refused with the following warning: "Couldn’t pair with BLE Slider and LED because of an incorrect PIN or passkey."

So I decided to use the CySmart app, but still the same problem.

and finally I get the following error "Cannot connect to device"

What am I doing wrong? I'm using a BQ Aquaris E4.5 with Android 4.4.2 version, so bluetooth low energy should be supported by the system API.

I am trying to use the 9-bit address mode with hardware address detection on a CY8C4245 and although it it one of the biggest PSoC 4 devices the design is not fitting (Resource limit: Maximum number of UDB Unique Pterms exceeded (max=64, needed=74)

Is there a way to get this functionallity in a PSoc 4 device? If not, why is it selectable in PSoC Designer? It's frustrating when advertised functions are not working in the real world...

Hi All

I am currently working on UltraSonic Sensor based Distance Measurement. I am using the sensor HCSR04 for that. With help of Danaaknight, I have designed the attached project, but it is not working as I am not getting the distance. The PSoC4 pins of trigger, echo and the sensor's results are checked on CRO. They are tested OK. I think the problem lies in measuring the time period on the Echo pin. Everybody is welcome to give solution.

Hi All,

The Android app for CySmart Spider is now available on google play. it will work with RGB Service mode.

data[0]- bit0 & bit1 used for CySmart Spider LED Light

data[1]- bit0 & bit1 controls the DC motor (clock or counterclock)

data[2]-  byte of data used to control the DC motor in Forward Direction. (PWM)

data[3]-  byte of data used to control the DC motor in Reverse Direction. (PWM)

give your vote for CySmart Spider here review.wizehive.com/voting/view/photocontest2015/29382/2971274/0

 Hi,

See the attached project.  It runs fine for a while, but eventually gets stuck here:

CY_NORETURN

CY_ISR(IntDefaultHandler)

{

    /***************************************************************************

    * We must not get here. If we do, a serious problem occurs, so go into

    * an infinite loop.

    ***************************************************************************/

    while(1)

    {

    }

}

Any ideas?

Thank you,
Tom

Hello,

I want to place a delay on my signal path

I try to use the Shift Register component [v2.30] : I connect only the reset, clock and shift_out pins.

Nothing comes out on shift_out pin : I expected that 8 clocks after the reset this pin will get to high level....

Where did I get wrong ?
