PSoC™ 4 Forum Discussions

Hello,

I am trying to use a microcontroller that is as small in size as possible to fit along with a miniature camera that has it's own set of registers (to be programmed using CY8C4014FNI-421A), on a single board. It will be great if someone could advise me on the smallest possible microcontroller that I can get. I searched in Cypress Website and it seems like CY8C4014FNI-421 is obsolete and CY8C4014FNI-421A is in production. So I chose to use CY8C4014FNI-421A for setting up the camera registers. But my concern is with the CY8CKIT-042 PSoC 4 Pioneer kit. I have one that I bought recently for the I2C communication. I am not sure whether I can program a PSoC 4000 series microcontroller (CY8C4014FNI-421A) with the PSoC 4200 pioneer kit. I wanted to use the 4000 series microcontroller as it is much smaller than any other family series.

Please kindly advise me on this concern as soon as possible since I am currently working on a high priority project that requires this microcontroller for testing purpose.

Thanks & Regards,

The website product page has links to basic information about the device, starter kit etc but little in the way of detailed component module and register level information. Specifically interested in the PWM blocks, but if there's a document that contains everything that would be better.

I am using the PSoC 4 CY8C4248LQI-BL483 device. My program is using the WDT to wakeup from DeepSleep mode every 100ms

to update my User Application's LCD display information and perform other task before returning to the DeepSleep mode.
However, I also need to have a 2nd source to wakeup from deepsleep - the UART serial port. Although I have tried the
UART Interrupt and the "Wake from DeepSleep" option, I can't seem to get the right functionality I am looking for.
Is there a way to use the WDT timer and a 2nd UART interrupt to have both or either one wake from DeepSleep mode?

Hello,

I have recently updated a PSoC4000s CapSense project from Creator 4.0/ CapSense P4 v3.1 to Creator 4.2 / CapSense P4 v5.2.

In the process I noticed that the Creator  Tuner v5.2 "sense tuner" does not connect to my MiniProg3. I Get "Bridge Status: Disconnected"

When I press Connect, I Get: "There was an error reading data from the device"

I have triple checked the EZI2C settings vs the Tuner Com Settings and they are correct. I can use the older Creator 4.0 tuner and it connects right away.

I am a bit stumped, wondering if this is a bug?

Thanks,

Adam

Dear Sir,

As we knew, the T device and non T device themselves are different package.

But, customer would like to know as subject and have any file or document to clarify that.

Thanks

Dear Sir,

I could see the datasheet of page 34 to know the Part Numbering Conventions of it-CY8C4ABCDEF-XYZ, but now customer ask why no includes T on datasheet.

Would you help to provide the complete code file that includes T or where i could download?

Thanks

Hello,

I have a CapSense slider project using the PSOC4000S that is giving me a bit of trouble at power up. I am getting a large sensor reading at startup that takes about 45 seconds to settle down. During this time the slider is unusable. The slider controls an LED light via PWM, it constantly flickers and is extremely annoying during this period. It is not something I could live with for a final product. Once settled it works well enough.

Can I eliminate this issue?

Some details:

- 45 seconds for the signal to settle, and the rawcount/baseline to follow each other.

- overlay 2mm wood

- Slider adheres to design guidelines

     - 220mm length, 15mm height

     - 12 segment diplexed

     - 8mm wide chevrons

     - 0.5mm gap between sensors

     - 0.5mm gap between sense traces and gnd

     - 1.75mm gap between sensors and gnd

     - End segments attached to ground

     - Central sensor ground point at PSOC

PCB stackup:

- L1 Top (Components, signals, sense traces, gnd)

- L2 (sense traces, gnd)

- L3 (gnd)

-L4 Bottom (sensor, gnd)

- SNR of approx 19

I will attach images of my PCB, main.c, CapSense settings and tuner graphs.

I appreciate any input, Thank you.

Hello

I have a peripheral device that is advertising and provides scan request responses. Can this peripheral device get the address of the central device via a scan request?

Thanks,

In the datasheet for PSoC4 and PSoC4 BLE we spec the IMO accuracy at +/-2%.  In the notes sections it states: "With API-called calibration"

http://www.cypress.com/file/416486/download Table 47.

1) What does this statement mean?

2) Does it mean that there is an API required to maintain this accuracy that the user is responsible to call?

3) Does Creator automatically take care of calling this API?

4) Does a function need to be called for any scenarios where we would need to re-calibrate? (switching frequencies for example).

I assume that these devices are factory trimmed but the statement seems to imply the user is responsible for calling a function to keep this accuracy in at least some scenarios.

I have a PSoC4-BLE device on a custom board. The device programs and the IMO and 32.768KHz oscillator spin up fine. The 24MHz oscillator does not start and does not run. Has anyone else run into a similar problem? The power supplies look good as far as I can tell, and the rails are thoroughly bypassed.
