PSoC™ 4 Forum Discussions

 Hi all,

is it possible to enable/disable shield of capsense configuration from application in CY8C4100 project? How?

    Thanks..

 Hi,

I was wondering if anyone knows if there is a way to battery back up the time for the PSOC 4 RTC component coming out in Creator 3.2 without backing up the whole processor?  If not, what is the point of the component other than a timer that counts in days, months, etc?  I am just wondering if this component in any way means I don't need my trusty old DS1307 any more.

Thank you,
Tom

Hi, I'm using the PSoC 4 CY8CKIT-049 and trying to get the fastest SW pin toggle.

I set all the clocks to the maximum of 48MHz, and set TestPin to P0[2].

then, I toggled the pin using

 for(;;)

{

TestPin_DR |= TestPin_MASK;

TestPin_DR &= ~IndexPin_MASK;

}

However, i only get a 1.337 MHz square wave, which means the pin is being toggled at 2 * 1.337 MHz.

Why is there such a discrepancy with the 48MHz speed? Shouldn't it only take two cycles to toggle a pin in this method? Would there be anyway to do it faster using asm?

Thanks so much!

 I need about 10 pieces of the 18 pin CYBLE-022001-00 package.

Boards were laid out before new package was announced.

Can anyone help?

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.

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

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.
