I bought the FX3 development kit, in order to program for the CYUSB3014.
- reconfigure the GPIF and other pins to specified inputs/outputs.
I have a project using CyAPI.lib in C++ Builder 6. Now i want to upgrade it to C++ Builder 2010.But the library CyAPI.lib available in C++ Builder 6 does not work in C++ Builder 2010.The simple code "CCyUSBDevice* USBDevice=new CCyUSBDevice()" generates error like "access violation".Is there a library available for C++ Builder 2010 ? Or is there any other way to solve this situation ?Show Less
i am using cypress high speed usb interface i.e Cy7c68001 and its external master is Ti 5416 processor. currently the throughput of sending/receving data from PC is 2.7Mbps. i want to get high speed (480Mbps)from it.
can please guide me about it.
I'm developing a host application in C# whose first step is to detect the FX3 as bootloader and then download a customized firmware.
It is done using the "DownloadFw(path, FX3_FWDWNLOAD_MEDIA_TYPE.RAM);" function.
For some reason it takes too long ~ 20 seconds to re-enumerate the device (the function returns after ~ 1 second).
I took that function call from the Control Center source code. Control Center re-enumerates almost inmediately and I'm not able to detect the difference in the code.
Does anybody know what is happening?.
P.D: DeviceAttached/DeviceRemoved events are registered in my application but they never triggers. They trigger correctly in Control Center application.
I am new to this environment and recently ordered the Cypress EZ-USB FX3 development kit.
My goal is to use this test board in order to do spi writes to another device.
How can I start ?
I have read all the documentation and little project USBBluk loop auto, but the SPI projects seem to work differently.
I have tried just compiling it and loading it on the board with the same steps, it just hangs at "Programming of SPI Flash in progress".
Is there a library of functions I could use to write my own DLL for example ?
I was trying to find more documentation or guides on the SPI bus, but returned empty handed.
I would really appreciate any help or advice,
When the host comes up again after hibernation, Windows complains about unknown device for FX3. if I remove the USB cable and pu it back then it works normally.
I have not done any firmware debug so far. Any possible reason this may happen?
I configure my CY7C68013A into the slave of auto mode. I test this process through the software Cyconsole. I use
the Keil V3.30. I use keil in on-line debugging. But I found a problem. I don't kown whether this is keil or slave configuration.
First, I transmit the data (0x03 0xA1 0x4c 0x6e).Then but when I hault the keil. I found the regisiter of EP2BUF is all 0x02 and 0x00. The regisiter of EP2BCL displayed that there is four data. The picture of second in the package.
Second, I transmitted the data(0x57 0x3b 0x4f 0xab). Then I haulter the keil. I found the register of EP2BUF is 0x03 0xA1 0x4c 0x6e. And the regisiter of EP2BCL displayed that there is eight data. The picture of third in the package.Show Less
