SLAVE FIFO USB TREIBER WINDOWS 7

If you are sending a smaller data less than 16 KB, but greater than or equal to bytes , use zero length packet ZLP to indicate packet end. If so, when you sent bytes of data and receive the same at the end-point, there won’t be any short-packet or zero length packet. I have just completed a simplified state machine that does not have any hidden “Mirrored” states and finally have an understandable function. To implement StreamIN data transfers some signals, listed in GPIF II-related connections , may be connected to the high or low level as shown below; please note that the active asserted signal level is low. Other documentation hosted on this wiki: To implement StreamOUT data transfers some signals, listed in GPIF II-related connections , may be connected to the high or low level as shown below; please note that the active asserted signal level is low. If you have written to all 16 byte “packets”, then there also needs to be a delay before writing the ZLP.

For this question ,I have question: It expects for more data and hence doesn’t give a DMA ready. To implement StreamOUT data transfers some signals, listed in GPIF II-related connectionsmay uab connected to the high or low level as shown below; please note that the active asserted slave fifo usb level is low.

The general steps for IQ sample writing are:. Tutorials – Blog Posts. Stream board information is returned by MCU as shown below:.

Before that, the Stream board has to be configured to send out data samples. It also has a strange slave fifo usb of having the state maching toggling between the Idle State and the DSS state slave fifo usb only the Chip Select input is active.

One pair of I and Q samples makes up one frame.

Other documentation hosted on this wiki: Various expansion boards may be connected to the Stream board. About Us Investors Careers.

Privacy policy About Log in. That will trigger the DMA ready signal. Becomes asserted when there are 0 not read words. The general steps for IQ sample reading are:. The control endpoints should be configured as shown below. If so, when you sent bytes of data and receive the same at the end-point, fido won’t be any short-packet or zero length packet. If you have written to all 16 slave fifo usb “packets”, then there slave fifo usb needs to be a delay before writing the ZLP.

Due to I don’t want to send one more dummy ZLP. fifi

RSS Back to Top. Before that, the Stream board has to be configured to accept incoming data.

The Slave fifo usb board has a Si clock synthesiser onboard. One issue may be related to the buffer created. Stream board samples uses 1 bit for I or Q channel selection and 12 bits for amplitude. It is not possible to read the slave fifo usb data from ADF But, when you sent bytes us any multiple of except 16 KBit is not a short packet.

The SPI registers are shown below. For example, bytes. The flags indicate the availability of an FX3 socket.

So, you won’t get DMA ready. So, you get a DMA ready. Flag outputs from FX3.

I am using USB 3. If you are sending a smaller data less than 16 KB, but greater than or equal to bytesuse zero slave fifo usb packet ZLP to indicate packet end.
