USB low-full-high speed peripherals Forum Discussions

HI,

I have defined an another endpoint 2 in fx2lp slave fifo firmware with OUT,4x ,Bulk (register settings -> EP2CFG = 0xA0;)

if i click transferout button  times,bulk out transfer is successfull.if i click transferout button more than 4 times,its giving 997 error.

if i change register setting as EP2CFG = 0xA2; that is OUT,2x,bulk and if i click transferout button more than 2 times,its giving 997 error,first two times request is working.whats the issue.

regards,

geetha.

Hello,I am using fx2 to read data from a image sensor with 2592*1944 bytes ,I  got data up to 4194304 bytes correctly and rest of the bytes were zeros. Is there any maximum limit for the receiving data in the Slave fifo mode or in the xferdata function.

Best regards,

Sandeep

Hi all,

I am working on Cypess FX-3 I2C interface .My slave device is EEPROM his memory address length is varying depends on function. how to select the control mask value if different memory address length read and write operation.

Read operation:

given example code

if 1 byte --- ctrlMask=0x02

if 2 byte ---- ctrlMask = 0x04

Q1. Therefore what is the value of ctrlMask in 3-byte, 4-byte and 5-byte address?.

Q2. what is value of ctrlMask in case of repeated Write operation.?

Thank you.

Best regards,

Hi,

I am looking for a processor [or a few options] -

USB  to analog audio in and out.  Only need stereo out, mono or stereo in is ok.  No fancy audio processing needed.

Also need a few GPIO pins that can watch for a contact closure, and trigger software to simulate a short key sequence via the USB as if it were a USB keyboard.  

If there was one with onboard CODEC that's even better, but I'm thinking more likely to have to use a separate audio CODEC, but it only needs to be a simple one.

Hi,

I'm task with figuring out, why our USB communication randomly is in-stable. In a USB trace I was able to locate the following strange behavior, where the ACK on the setup package seams very late (see image below). I was wondering, under which circumstances is such a behavior can be expected?

I'm relative new to such low level debugging and would welcome any hints.

I am using my own board and I cannot connect to the Cypress config tool.  It is detected by the tool but fails on connection.  I can use the COM port without any problems.  I didn't have this problem with the CYUSBS234 kit.  Does anyone know what is the problem?  This is the image of the error:

Dear cypress experts,

I came a System.OverflowException when build with CyUSB.dll，at win10+x64+VS2012/2013/2015+.net4.0, build as debug+x64

is there a CyUSB.dll for win10+x64+VS2012/2013/VS2015+.net4.0? or could I download the source code of CyUSB.dll and rebuild it?

Thanks for your time。 Looking forward to your response.

By the way, CyUSB.dll in CyUSB Suite 3.4.7 works fine when it's win7+x64+VS2012/2013/2015+.net4.0 or win10+x64+VS2010+.net4.0 or win10+x64+VS2012/2013/2015+.net 3.5. By at win10+x64+VS2012/2013/VS2015+.net4.0, this System.OverflowException will occur.

Visual Studio 2015 first doesn't like the project file and requires you to upgrade the project file. Second

when you do get to where you can build it gives 53 errors. I suspect there is some header file missing.

Any ideas ?

Hello,

I need to know if there is a USB cable connected or not. How can i do that. I need this for reading by an FPGA

Thanks for your help

Hello,

I am using CYUSB232 RDK to check the operation of CY7C65213-32LTXI.

After connecting the device to the USB, its TXD line is High.

However, once the port is opened / closed by software (ex. TeraTerm Pro), the TXD line becomes indeterminate(Probably Hi-Z state).

Therefore, incorrect data will be sent to the receiving side.

Is there a way to avoid this situation?

Thanks,

Shimamura
