PSoC 4 MCU

現在 製品試作に実装しテスト中ですが
UARTでフレーミングエラーがまれに発生しており 原因と対策を検討中です
型番：CY8C4147AZI-S475

質問は
UARTのMedian Filterが どういう仕組みで 外来ノイズに対して 有効なのかどうかを知りたいです

の Median filter の項目についてですが
This parameter applies 3 taps digital median filter on input path of RX line. This filter reduces thesusceptibility to errors.
The default value is a Disabled.
このパラメーターは、RXラインの入力パスに3タップのデジタルメディアンフィルターを適用します。
このフィルターは、エラーの影響を受けやすくします。 デフォルト値は無効です。
と 機械翻訳では ”エラーが起きやすくなる” ような 意味になるのですが
実際にはどうでしょう？ また それを使用した時の 弊害はあるのでしょうか？

I've been learning how to use PSoC by the tutorial vids. In lesson 4 I encountered a problem, when it came to the hardware connection between the switch and the LED.

The error is: "Pin guidance unavailable. Pin cannot be placed at X. Pin cannot be used for routed connections." for both the input and the output pin as soon as i connect them by wire in my TopDesign.

The goal would be to directly turn on the LED by pressing the switch as described in the tutorial.

Is this a configuration problem or is my board not able to do hardware connections (which I doubt).

I'm using PSoC Creator 4.4 and the CY8CKIT-149 PSoC 4100S Plus Prototyping Kit, CY8C4147AZI-S47564.

I attached the project.

I'd be very grateful for an explanation of this error and even more for a solution.

In my application Psoc4 has to serve a device that could be configured  in SPI or parallel mode during runtime. In SPI mode pin named D0 has to be configured as MTSR, D1 has to be configured as SS,  D2 has to be configured as SCLK and  D3 has to be configured as MRST. In parallel mode  D0...D3 are part of the parallel IO (D0...D7) offering bidirectional IO. How to implement this switch on the fly?

How do I send a BLE packet communicating a double click from a CapSense Trackpad device? I'm using a CYBLE-214015-01 module to build a trackpad, up to now I can send Clicks (Code examples helped) but I don't understand how to send double clicks.

Is there a manual for setting specific bits? Should I send 2 clicks in a short time period?

Thank you

Dear all,

I'm working on CY8C4245AXI-483 MCU. I want to write a code to toggle LED through capsense touch button.  it means, initially LED is OFF. now when i touch button it should be ON. and remains ON untill i touched it 2nd time. after touching 2nd time it should be in OFF condition and remains in OFF untill i touched it 3rd time and so on.

i found code for same, somewhere on internet. is this correct or i need to change something? Please give me your valuable suggestions.

Thanks & Regards,

Prem KB

Hello there!

I tried getting used to PSoC by doing the 101 video tutorial. 

As soon as i hit TCPWM blocks i encountered a problem: I can't seem to be able to use the clock block. Whenever I add it to my design, I get the error message "Clock "X" specifies a GLOBAL clock. Max of 0 Digital global clocks already used up."
In the video it worked just fine and i doubt my kit is unable to use something as basic as a clock, so I'm hoping you guys can give me some advice.

Cheers!

Hello, 

I am using the CYBLE-214015-01 chip to transmit x & y positional data of a trackpad to an application. In this application, I determined the time stamp when the notifications were collected. From this time stamp, I determined the frequency between consecutive notifications. In plotting the frequency spectrum, I noticed that there is a large range (between 50-1000Hz) of frequency values. I am curious if there is a logical explanation as to why the frequency between consecutive notifications is so variable. 

Thank you,
