HI Cypress Team,

I am using Part#  CY8C624ABZI-S2D44 . and wanted to interface digital microphone.

Where the confusion was which pins can be used for PDM /I2S microphones interfacing? 

- IS there any specific Pins which should be used for PDM /I2S Microphone interfacing?

- If yes please let us know the details? 

- Also please share me the pin-muxing possible for 2x PDM channel and 2x I2S interfaces.

I use the example code in FX3 SDK for Bulkloop_SDCC of FX2LP

I want to enable the external interrupts.

It works well for INT 1/2, but it doesn't work for INT 4/5/6.

It seems can't run into interrupt 10 / 11 / 12.

What's wrong here?

In the TD_Init()

//INT4#
INTSETUP &= ~0x02; // If INTSETUP.1=0,then INT4 is supplied by the pin.Else, the interrupt is supplied internally FIFO/GPIF sources.

//INT5# is a dedicated pin , available in the 100 amd 128 pin packages.
//INT6#
PORTECFG = 0x20; // PE5 is INT6
OEE &= ~0x20;

//Enable External Interrupts
EIE |= 0x1C; // Enable External Interrupts 4, 5 and 6
IE |= 0x05; // Enable External Interrupts 0 and 1

//Clear Flags
EXIF &= 0xBF; // Clear INT4 EXIF.6 Flag
EXIF &= 0x7F; // Clear INT5 EXIF.7 Flag
EICON &= 0xF7; // Clear INT6 EICON.3 Flag
EA = 1; // Enable Global Interrupt

// for interrupt function

void ISR_EXTR4(void) __interrupt 10
{
EXIF &= 0xBF; // Clear INT4 EXIF.6 Flag
IOB ^= 0x08; // Toggle pin 3 of PortB
}

void ISR_EXTR5(void) __interrupt 11
{
EXIF &= 0x7F; // Clear INT5 EXIF.7 Flag
IOB ^= 0x08; // Toggle pin 3 of PortB
}

void ISR_EXTR6(void) __interrupt 12
{
EICON &= 0xF7; // Clear INT6 EICON.3 Flag
IOB ^= 0x08; // Toggle pin 3 of PortB
}

//USB jump table

.area AUTOVECTOR (CODE,ABS)
.org 0x0043
ljmp _USB_Jump_Table ; Autovector will replace byte 45

.org 0x0053
;; USB_Int4AutoVector equ $ + 2
ljmp _USB_Jump_Table ; Autovector will replace byte 55

what do I miss something?

Hi LCY Community,

SDK only DCP &  CDP , how to new add SDP connected?

What is the process to verify USB compliance for any Infineon component that supports USB?

I found an obsolete document that had listed products that were compliant: "USB COMPLIANCE TESTING OVERVIEW - AN023" @  https://www.cypress.com/documentation/application-notes-obsolete/an023-usb-compliance-testing-overview <-- Is there an updated version available for public view?

Another page I found instructs an e-mail be sent to hx3@infineon.com to request an individual report for one specific product, "HX3 USB 3.0 HUB Controller Certification Report (USB-IF, WHQL, CE)".  If that e-mail is intended to support requests to obtain compliance reports for any USB product, it would be helpful if it was linked to each product, searchable using the words "USB Compliance", or listed on the "USB COMPLIANCE TESTING OVERVIEW AN023" page.

Aside: An alternate approach to verifying compliance through USB.ORG appears to require a log-in to search. Reference products list linked @ https://www.usb.org/compliance and https://www.usb.org/products .

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)

Best regards,
Naoaki Morimoto

Is there any publicly available official firmware for the SDIO-based chip 43456 found in e.g. Pinebook Pro? There is a firmware distributed by Manjaro at https://gitlab.manjaro.org/tsys/pinebook-firmware/-/tree/master/brcm , but there's no information about its origin and it's crashing often with 5.11.x kernel on Fedora 34. I opened an issue on Github in the firmware repo, too: https://github.com/cypresssemiconductorco/ifx-linux-firmware/issues/1 .

Dear Sirs and Madams,

Please tell us because there are specifications that We don't understand about IDAC of PSoC4.

Below is an excerpt from the IDAC component data sheet.

Please tell us about the specifications of this "IDACMISMATCH".

(a)

Does this "IDACMISMATCH" spec mean that even if the same value is set for IDAC1 and IDAC2, different currents will be output for the number of bits above?

(b)

If so, why is MISMATCH so large even though DNL and INL are at most 2 bits?

Regards,

Hello，

I have built a UVC project and observed with an oscilloscope that the sensor can output the correct clock and data signals, but I can't receive any image data on the PC side with a USB hount.

I just implemented UART debugging and when I download the .img file to my hardware, I can observe that the UART can print the configuration information of the sensor, but the video streaming information and the MIPI error information I want to observe will not be printed.

I would like to know why this is happening, it seems to be gone after the sensor configuration is done. How can I find out where the error occurred?

My CX3 does not have the MIPI output interface for signal analysis, so I can only observe the output of the sensor.

Best Regards,

Yaqi
