Greetings,

The GX3 datasheet has maximum time for RESET# assertion.  Why is this not infinite?  Shouldn't I be able to assert the reset indefinitely?

In Table 18: Trst_pu min=0ms, Max=10ms.

Under Table 20. Reset Timing Parameters: "If the system applications require using hardware reset pin, RESET#, to reset GX3 during device initialization or normal operation after VBUS pin is asserted, the above timing spec (Min = 5 μs, Max =10 ms) of RESET# should be met."

Thanks

Dear sir,

I am debugging the CY3014. Now the firmware is stream example, and I also enable the CDC.

When I tring to control it in control center, I got an Error dialog about the ".net framework".

The cy7c1062dv33 was used on the CYUSB3KIT-003 board that I have used and tested with. Now I am trying to develop my own board and the SRAM IC is obsolete. What would be the recommended SRAM IC to use? For context I am mostly using the synchronous 32 bit FIFO where the FPGA is only writing data to the CYUSB3014. 

Hello all 

I am currently attempting to automate and a plug-in to the Cypress EZ USB Suite this is an older IDE  version 2012 

I keep getting a popup when attempting to connect to the marketplace 

"Connection failed

This is most often caused by a problem with your internet connection. Please check your internet connection and retry.
Read timed out"

is there any way to direct this to the correct location. the build server I am on clearly has internet access as I am typing this email.

Hello all 

i am currently trying to automate the build and compile of the Cypress EZ USB IDE and 3 associated projects. 

At present I can open the IDE to a certain Workspace, but I cannot find a way to Clean, Build, Compile via Command Line. 

Is there a reference document somewhere >?

thanks

Hello,

I'm using the Cypress example code projects to try to get data from an accelerometer (ADcmXL3021). I'm using the UsbSpiDmaMode project, where I've merged GPIO functionality into it.

When I'm trying to communicate with the accerlerometer, I'm using SPI communication. The UsbSpiDmaMode already has functions set up for this; CyFxSpiTransfer (programmer application), which uses the two functions CyU3PSpiTransmitWords and CyU3PSpiReceiveWords.

Currently, I've tried making my own functions to write and read data over the SPI interface. They look as follows:

with startSampling() and readData().

As you can see I pass in 0x3E, 0x08, 0x00 as my input, which you can also read in the datasheet for the accelerometer are the registers that start recording data. The datasheet can be found here:

https://www.analog.com/media/en/technical-documentation/data-sheets/ADcmXL3021.pdf#page=42&zoom=100,45,574

(where 0x3E is the address for GLOB_CMD and 0x08 (0x0800) is the address to start recording).

My output gives the same values, which implies that I'm using the functions incorrectly. Below, my data value (200 entries) are seen from the UART debugger:

It would obviously be best if I could use the given function, CyFxSpiTransfer, but I get stuck in the CyFxSpiWaitForStatus() function when I try using it with the call: CyFxSpiTransfer(0x003E, 0x0800, 4, CyFalse)

(I'm unsure what the 3rd parameter means (*buffer).

I've seen you're employee, juchong, has made a GitHub FX3 API which includes this accelerometer, but I can't seem to understand it and how it works (I'm new to this world). It's found here:

GitHub - analogdevicesinc/iSensor-FX3-API: A .NET API and firmware for the Cypress FX3 USB interface IC that interfaces …

Moreover, can I use the CyU3PSpiTransferWords function to combine the two (transmit and recieve) into one? If so, that would be much better of course.

If you could tell me where I go wrong, in the calls of the given functions, it would help me out very much! I hope it's a simple fix. All I want to do is invoke the RTS mode (later the MFFT mode) of the ADcmXL3021 accelerometer, and get a single reading of the mode for each iteration call from the main function of my program (located in the AppThread_entry function). The AppThread_entry function looks like below:

Hope I've provided enough information, other please tell me if you need more information. I've also attached the C-file to this message.

Sincerely,

Søren

Hi All,

I'm feeling very stupid asking this question, here goes. I'm using Visual Studio 2019, have used the functions in CyAPI.lib without any problem.

I'm now using CyU3PDeviceGpioOverride and CyU3PGpioSetSimpleConfig but these don't exist in CyAPI.lib.

So in a pure Windows environment how do I link with these functions or must I write them myself as they are overrides?

I've downloaded everything from the downloads page, still none the wiser.

Dear Sir,

I designed a custom board with CY3014+FPGA for slavefifo stream-out function for printer purpose.

The config are : GPIF interface external PCLK 48Mhz,32bits,slave fifo out. 

While testing,all works OK but sometimes my PC side application(C) showed a problem of transfer failed,err code =997 and could not send data anymore,once close program and re-run ,and it could send again.Unstable.

I verified it by download USBBulkLoopAuto.img to cy3014 , and tested by Bulk Loop.exe for loopback test , no problem .like pictures attached.(sorry,I found I have no permission to upload images yet).

So,means PC->driver->usb 3.0 cable ->CY3014 chip loop back are all normal.

Then,I switched back to my slavefifo.img  and  run Cypress Streamer. 

At first,it worked fine,however, some minutes later, the receiving is stopped and the error message is "Xfer request rejected. NTSTATUS = c0000001".

The interface between CY3014 and FPGA are simple :

32bits data(could be ignored here before problem cleared).2 bits address.

/CS and /OE are GND.

PCLK= supplied by FPGA 48Mhz.

My side,only control /RD ,depend on FX3 /empty signal.

No matter controlled /RD signal,or simply treated /RD=!/EMPTY , all have problem as above red text.

One more clue,before I click steamer START,I select end point and it showed"BULK OUT,16384 bytes,15 maxburst"

Once problem occurred, the end point change back to default "IN...".

Any idea will be appreciated.

Thanks.
