Dear Sirs and Madams,

We are considering a PSoC4S UART (SCB) component. 

Therefore, we are verifying the problem due to the timing of UART communication.

The configuration of PSoC4S UART is as follows:

One frame of UART communication is as follows:

(1)

As in Expansion 1, the clock accuracy of PSoC 4S is +/- 2%.

Since one UART clock can have an error of 2%, there is a possibility that an error of 20% will occur in the final stop bit of 2% x 10 bits in 10 bits of one frame.

Is this perception correct?

(2)

As in Expansion 2, shows the relationship between RS-232C and PSoC4S master clock.

When the maximum error as in (1) is considered,

Do you know what number of the master clock the timing that PSoC4S takes the UART data into the register corresponds to?

Regards,

Hi All,

I am using CY8C5467AXI-LP108 chip.

I am having difficulty to compile these analog pins:

P4_3/PIN81

P15_4/PIN93

P15_5/PIN94

Receiving this error message:

"apr.M0003:Unable to find a solution for the analog routing."

I have looked up in the datasheet and didnt see any problem using these pins as analog pins.

This is my schema, all the other analog pins are good and fully functional:

Hello,

When I'm trying to write data to Fx3 device from a FPGA device, I always get zero-lengh data transfer despite buffer being full (I know it is full base on the state of DMA flags). I noticed strange behavior of my RDY signal in a middle of a transfer it goes low for some reason and after few clock cycles it goes high (as it should be)

In attachment i'm sending you firmware which I use and state machine from GPIF designer

割り込みポート（INT）は、最大何本、どこのポートに割り付ける事ができるのか？

割り込みポートのシンボル名は何か？

How many interrupt ports can be assigned to which port?　

What is the symbol name of the interrupt port? 

PSoC4200 DataSheet(002-00008 Rev. *B) reference.

Hello,

I am testing the PSoc  4100S Pioneer kit that has KitProg3, I see the programmer, but not the MCU with PSOC Creator:

The strange thing is that I can read and write with PSOC Programmer:

Do you know the issue ?

Best regards

Luca

Env: Ubuntu 20.04, SDK1.3.4_linux

The thing is no matter use cyusb_linux or download_fx3, flash programmer can be loaded to RAM successfully, but the SPI part failed. the terminal log is as below

```

➜ cyusb_linux_1.0.5 ./bin/cyusb_linux
Found FX3 flash programmer
SPI sector erase failed
Failed to erase SPI flash

Thanks in advance!

Hello,

I have been requested the marking information of PSoC4100S.
I refer the document of CYPRESS MARKING FORMAT JANUARY 2020 (https://www.cypress.com/file/41321/download) , but specified information of WLCSP 35L is different from the actual IC marking.

Please confirm my understanding and provide the correct information.(see attached file)

MPN: CY8C4146FNI-S433 (WLCSP 35L)

Dear Sirs and Madams,

I would like to translate AN231295 of legacy cypress, please confirm to my work.

Hello，

I created a new CX3 UVC project, I modified the imagesensor.c file and added CDC interface for UART debugging in the project.

My problem is that after downloading the configured .img file to the hardware, I can open the camera software and drive the camera normally but there is no image.

My UART log is as follows

I enabled CX3_DEBUG_ENABLED and SENSOR_DEBUG, the only result printed is the above and the register configuration.The following information that I want to observe is not in the UART log.

I would like to know what should I do next for debugging,hope someone can help me, thanks a lot!

Best Regards,

Yaqi
