PSoC™ 5, 3 & 1 Forum Discussions

Not sure if everyone has seen this -

"This spreadsheet is a basic tool for obtaining a gross estimate of power consumption using

PSoC 3 ES3 and PSoC5 ES1."

Hopefully will be done for 4 and 5LP.

Hi,

I organized  a header file but I have error. What I'm missing.Can you look please?

Hello,

I have a doubt about configuring a DMA with two TDs. For example, the first TD (TD[0]) goes from position 0 to 63 of an array, when it finishes, it switches to TD[1], where it goes from 64 to 128 of that same array. The first part is done correctly, however, the second part, the DMA is not transferring correctly the array's data.

I have set up the configuration as below:

-------------------------------------------------------------------------------------------------------------------------------------

CyDmaTdSetConfiguration(dmaDescriptor[0],

        TEXT_MESSAGE_LENGTH*2, dmaDescriptor[1],

        (TD_INC_SRC_ADR | DMA_1__TD_TERMOUT_EN));

    CyDmaTdSetConfiguration(dmaDescriptor[1],

        TEXT_MESSAGE_LENGTH*2, dmaDescriptor[0],

        (TD_INC_SRC_ADR | DMA_1__TD_TERMOUT_EN));

    CyDmaTdSetAddress(dmaDescriptor[0],

        LO16((uint32)textMessage), LO16((uint32)UART_1_TXDATA_PTR));

    CyDmaTdSetAddress(dmaDescriptor[1],

        LO16((textMessage[TEXT_MESSAGE_LENGTH])), LO16((uint32)UART_1_TXDATA_PTR));

-------------------------------------------------------------------------------------------------------------------------------------

I think that the problem is that I didn't set up the offset correctly (I have tried using pointers also).

Thank you in advance

 Hi,

I´m using the "PSOC 3 Development Kit". In my project I would like to transmit data that has been received by a SPI SLAVE to my PC.

I tried to use USB_UART with Hyperterminal and  I did work, but i was to slow.  I need at least a datarate of  100 kByte/s. Now I'm trying to establish the data transfer with the USBFS in the Bulk mode using USB Suite. With CyConsole I´m able to read out the endpoint, but every time I want to read the data I have to press the button " transfer data" . But i need a continuous stream of data. The programm "streamer" does not work. Does anybody know how its possible to read out an store a continuous stream of USB data?

I attached my project.Pease help me out.

Regards,

Alex
