USB low-full-high speed peripherals Forum Discussions

Actually it is the count parameter in this API for creating DMA channels, which is interpreted as the number of buffer zones to be allocated for the channel, can it be understood that which channel is configured, this parameter will allocate buffer zones for that channel? I can understand that which channel is configured, this parameter will allocate cache area for that channel?

Hi, Support,

I obtained a file named "files for command line utility.zip" from the forum, which includes a method for generating firmware and programming for CY7C65211. In the Decryption Utility directory, using the tool provided, I managed to generate default_CY7C65213-32LTXI_decrypted.cyusbd from default_CY7C65213-32LTXI.cyusb. However, after programming this firmware into the CY7C65211 device under Linux, the device can no longer be recognized by Linux.

My goal is to enable USB to SPI functionality support on the CY7C65211 chip. I am unable to generate the corresponding firmware version on Windows in my current situation. Could you provide me with a .cyusb file that supports USB to SPI functionality for the CY7C65211 chip? Thank you very much.

status = OutEndPt- >XferData(writeBuffer, Wr_len, &Writteninfo);

At first I thought status represents whether the transmission is successful or not, and when it is 0, it means the transmission fails. At first, there has been no problem, and the reception on the FPGA side is also normal, and the return value of the upper computer is also 1, so I think it is a good idea for the FPGA side to receive the data.

The final return value is always 0, so I always thought that the sending failed, but today I caught the waveform at the FPGA end and found that the data was sent through, may I ask what the return value means exactly?

In the case that data can be received on the FPGA side, this value could be 0 or 1!!!?

hello guys, i met a problem about cypress resolution, i want to get a 1216*1200 resolution firmware,but after i change the code related and programmed it into the cypress but it failed to get the pircture. into the cypress but it failed to get the pircture.
so i wonder if cypress support the 1216*1200 resolution , or i made some mistakes?

thanks!!!!!!!!!!!!!!

IPAD Also support PD9V fast charging OTG chip has the right one?
