PSoC™ 4

I'm using a CY8C4045LQI-S411 and PSoC Creator v4.4.  I have a SPI port using SCB[1] configured as a slave.   I am able to route miso_s to P0.5, mosi_s to P0.4, and sclk_s to P0.6, however I am unable to place ss_s.  The PSoC 4000S Datasheet shows that SCB[1].spi_select0, 1, 2, and 3 are on P2.3, P2.4, P2.5, and P2.6, respectively.  However, in the CY8C4045LQI-S411 (a 24-pin package), the only one of those that is available is P2.6.  It appears that PSoC Creator only wants to use spi_select0, which isn't available in this package, instead of spi_select3.

HI all,

I have been developing a small board and application for CY8C4245 using I2C bus.

unfortunately, due to the current supply chain problems, we had to select a 4745 for our design, so we can release the product much sooner.

I configured the I2C exactly the same way as the 4245 in PSoC creator, but I have problems with the communication with 4745.

I have looked at everything I could but can't figure out why it doesn't work the same way... 😞

Am I missing something?

いつもお世話になっております。

お客様のアプリケーションにて、

現在1/4デューティ, 1/3バイアス,A波形,HighSpeedモードでLCDを駆動しております。
GPIOピンのDrivemodeを変えると、動作が変わります。
・ストロングドライブ⇒PWMのdutyを変化させ2/3VDD,1/3VDDを生成
・プルアップ、プルダウン⇒電圧レベルを変化させ2/3VDD,1/3VDDを生成

LCD駆動波形が変わるのは仕様でしょうか。
LCDを駆動させる場合はピンの設定はどの駆動モードにすればよろしいでしょうか(特に指定はない?)

ご教示いただきたく、よろしくお願いいたします。

So, I am a complete newbie in the Cypress MCU family or PSoC creator. I am just trying to get started with the first project. I am using CY8C4014SXI-421, I have browsed through some of the documents like

1.  Getting Started with CapSense
 2.  PSoC® 4 and PSoC 6 MCU CapSense® Design Guide
I have also browsed youtube for the PSoC creator tutorial and I followed the step to create my first project, but I am unable to get through. Youtube tutorial is from Cypress itself, Basic Capsense Implementation 

I am getting errors: undefined reference to `CapSense_CSD_Start'

It's a linking error but I am don't see any linking method in a document or video tutorial.

However there are further questions from my end, which may seem naive, but I would like to get it cleared,

1. I need to know what approach to follow for touch detection is it CSD or CSX, I have to design 3 button detection, the button diameter is 25-30mm.

2. what is the difference between CSD and CSX, as I read CSX that is a mutual cap, is better than CSD. but in my case should I use CSD or CSX, pin configuration for both will be different, also I have sensed the touch even when the finger is like 10cm away from the surface, so in that case, using CSD is the right approach or to use CSX does use CSD or CSX depends on this?

3. how to integrate Guard/Shield connection in PCB?

4. also what is an example project to follow to start with the touch button? I would like a recommendation for the Evaluation kit and sample project to help me out

5. also in PSOC creator I see 2 options, Capsense v7.0 and Capsense CSD v2.6, I don't understand the difference between 2, as I see in the video tutorial I just ahs Capsense, which one to use?

Also i am trying to run example Capsense_CSD_P4 but it is showing following error:

Pin guidance unavailable: Invalid IoId location specified on placement_force attribute "PORT(1,4)" on component/signal "\CapSense_CSD:Sns(0)\".
