・English
Device Security is set to "PROTECTED mode".

I am thinking as follows. Are you sure?
"PROTECTED mode" does not run "Verify" of "PSoC Programmer".

・Japanese(日本語)
Device Securityを"PROTECTED mode"に設定しております。

以下の様に考えております。間違いないでしょうか？
"PROTECTED mode"では、PSoC ProgrammerのVerifyはできない。

Hello,

It can select Direct, SSC, PRS as Sense clock source in Fourth-generation CapSense.

According to the datasheet, when the Sense clock source is set to "Auto", the firmware chooses the setting for each widget.

Specifically, what criteria does it choose?

Also, can the user know which clock CSD is using?

Component version : 5.0

In the datasheet of PSoC 4, ESD_HBM and ESD_CDM are 2200 V and 500 V, respectively.

Are ESD tests conducted with both + and - polarities?

Or is it just +?

Hello, I am new to PSOC development and currently I'm using PSoC 4200L CY8C4246AZI-L433 for a simple brightness control with two push button switch connected to its pin.

Just want to understand how to configure PSOC4 where I can send PWM from let say P1.4 as output to control LED brightness with two push button switch say from P1.0(Down ) and P1.1(UP)? Is there an example related to this.Thanks

Hello,

We have used PSoC 4 modules and chips in some of our products.

But there is news that Infineon is to acquire Cypress.

So, wanted to know what will be the effect of this on the production of these PSoC modules/chips.

Will they be continued or they will become obsolete?

Please confirm.

Thanks,

Ameya

Hello,

I have CY8CKIT-042 PSoC® 4 Pioneer Kit. I need to configure this kit as master with SPI mode and need to drive some slave device.

I have got some example code from code samples, which used SCB1 configured as SPI(master) and have tested loopback(MOSI to MISO) which worked fine.

Now I need to configure SCB1_SPI as master which drives 24MHz to slave, as below.

But I am unable to do it. I have configured SPI as below. As per the TRM, this configuration must produce 24MHz clock for SPI but it is driving only 4MHz.

But in the clock section, I can see 24MHz for SPIM_SCBCLK.

Why there is a difference in SPIM_SCBCLK(24MHz) and SPIM:sclk_m(4MHz) which is driving?

Any other configurations, which are affecting the desired frequency of SPI? Please suggest.

Any suggestion should be grateful.

Hello all,

I am using cyble-014008-00 and I have a characteristic with notify property: when the characteristic is written a notification with the response is sent back

I am using cysmart to connect and read/write

Here you can find that notify is disabled, but the notification is received:

read Client Characteristic Configuration (ccc)

It seems that CyBle_GattsNotification does not check ccc

How can I read ccc and send the notify only if it is enabled?

・English
What can I do with "Unprotected" (U) and "Full Protection" (W)?

think as follows. Is this correct?
"Unprotected" (U) → bootloader, self-rewritable
"Full Protection" (W) → bootloader, self-rewriting not possible

・Japanese(日本語)
“Unprotected”(U)、“Full Protection”(W)はどのようなことができる設定ですか？

以下、理解で間違いないでしょうか？
“Unprotected”(U)→bootloader,自己書き換え可能
“Full Protection”(W)→bootloader,自己書き換え不可能
