Hi guys:

     I am developing with FX3.I am using UART DMA mode for data transfer.Now I want to store the data received by the UART in my own buffer.I queried through the API guide that the CyU3PDmaChannelSetupRecvBuffer API might be able to fulfill my needs.But this function always return ERROR message.I try to make some change in my code,but its error message will also change.

Frequent mistakes:

     -CY_U3P_ERROR_NULL_POINTER

or

     -CY_U3P_ERROR_BAD_ARGUMENT

or

     -CY_U3P_ERROR_ALREADY_STARTED

Here is my source code:

CyU3PDmaChannel glUartRXChHandle;
CyU3PDmaBuffer_t* glRxBuffer;
uint8_t glRXDataBuffer[16];
void ReceivedDataCallBack(
CyU3PDmaChannel   *chHandle, /* Handle to the DMA channel. */
        CyU3PDmaCbType_t  type,      /* Callback type.             */
        CyU3PDmaCBInput_t *input)
{
     CyU3PReturnStatus_t status;
     glRxBuffer->buffer = glRXDataBuffer;
     glRxBuffer->count = 16;
     glRxBuffer->size = 16;
     glRxBuffer->status = NULL;
     if(type == CY_U3P_DMA_CB_PROD_EVENT)
     {
     //status = CyU3PDmaChannelGetBuffer(&glUartRXChHandle, glRxBuffer, 0);     
         status = CyU3PDmaChannelSetupRecvBuffer(&glUartRXChHandle, glRxBuffer);
         if (status == CY_U3P_SUCCESS)
         {
              testBuffer[0] = 0x01;
              SendData(glRxBuffer->buffer, 16);
              //SendData(testBuffer, 16);
         }
          else

               DPRINT("RXData ERROR : %d",status);

     Please give me some help! Thank you !

We are doing one solution based on Wi-Fi and BT combo module. While surfing the internet we are not getting datasheet of Cypress CYW43012/BCM43012 datasheet. Does it contain network stack on it?

Hi guys:

     I use FX3 to implement UVC protocol and video transmission in SS mode of USB3.0..

     I have used DMAMutilChannal for video data transmission,use register mode for serial data transmission.But now serial data transmission seems to be apart from some problems.So I want to use serial DMA mode for data transfer.

     I would like to ask FX3 to support the use of two different types of DMA channels?In other words, can I use DMAMutilChanel for video transmission and DMA mode for serial data transmission?If there is support, is there a example to refer to?

Best regards,

Luca L

Hi there,

We have modified the circuit of OVP and OCP from EVK of CCG4. How do I start to modify code happen? Should I modify source code directly or use EZ-PD utility first.

Actually, we have more customized circuit from CCG4 EVK.

Modification

1. The EC host boot loader function without the HCI pin. We wanna update from I2C directly.

2. The OVP and OCP has been use some GPIO as notified pin.

3. Sink or Source path control.

We would like to modify to as we want.

Where should we start? Go to source all the way or still need EZ-PD configuration ?

Hi,

Looking into how to use linked mailboxes with Full CAN communication I find that the documentation is not very clear and the answers to the questions on the topic are a bit vague.

Could someone please provide a code example on how to use Full CAN linked mailboxes? It would be awesome if the example could include the following cases:

• Using the linked mailboxes as a buffer, that is, checking the linked mailboxes from time to time to retrieve messages even if the buffer is not full (not having to wait for an interrupt in the last linked mailbox to retrieve the messages that have arrived). Is there a way to know, be it by interruption or any other method, how many messages have arrived?
• Using the linked mailboxes as a FIFO buffer. Does this have to be done manually?

Hi,

I have a fresh install of the Wiced Smart SDK version 2.2.2 but I am unable to launch the IDE after the install and get a Framework Event error: Is this related to eclipse version bundled with the SDK being too old and not work with the latest version of java installed on my machine., Anyhow how do i fix it.

Hello Team,

I am unable to create a project using PSoc Creator 4.2 targeting a PSoc4 4100PS series of device. There is no option for 4100PS.

Hi.

Can I
get Address pinmap information for CY7C1643KV18(144Mbit 8Mx18 400MHz Latency 2.0)

I don't know pinmap information as from your datasheet(CY7C1643KV18)

please, help me ^^*

Could somebody give me a help.

I want to set the timeout of BulkInEndPt, but it seems that it doesn't work normally.

For example, I set timeout to 5ms, m_pCyUSBDevice->BulkInEndPt->TimeOut = 5;

If XferData returns and fails, it takes about 55ms. I think It should be 5ms or just a little more than 5ms. Am I wrong?

And if XferData returns and succeeds, if will takes much more than 5ms sometimes. I think it should be timeout.

What's more, I repeat reading data from USB device, and I am sure USB device have data, but it will stop reading data for more than 30ms sometimes. I find it by wireshark.

Thanks!
