Hello

I try to setup an isochronous endpoint to read data from an external application. As it did not work out, I setup the following minimal example which does not work either. The example should simply feed the computer with data.

WORD i;  REVCTL = (1 << 1) | (1 << 0); // DYN_OUT, ENH_PKT SYNCDELAY;  CPUCS = (2 << 3) | (1 << 1); // 48MHz CPU clock, CLKOUT enable SYNCDELAY;  IFCONFIG = (1 << 7) | (1 << 6) | (1 << 3) | (3 << 0); // internal 48MHz FIFO clock, asynchronous I/O, slave FIFO SYNCDELAY;  EP2CFG = 0; // EP2: off SYNCDELAY; EP4CFG = 0; // EP4: off SYNCDELAY; EP6CFG = (1 << 7) | (1 << 6) | (1 << 4) | (2 << 0); // EP6: valid, in, isochronous, 512B, double buf SYNCDELAY; EP8CFG = 0; // EP8: off SYNCDELAY;  RESETFIFOS();  EP2FIFOCFG = 0; // EP2: off SYNCDELAY;  EP4FIFOCFG = 0; // EP4: off SYNCDELAY;  EP6FIFOCFG = (1 << 0); // EP6: 16bit //EP6FIFOCFG = (1 << 3) | (1 << 0); // EP6: AUTOIN, 16bit SYNCDELAY;  EP8FIFOCFG = 0; // EP8: off SYNCDELAY;  PORTACFG = 0; SYNCDELAY;  FIFOPINPOLAR = 0; // all FIFO control pins low-active SYNCDELAY;  USE_USB_INTS();  ENABLE_SUDAV(); ENABLE_USBRESET(); ENABLE_HISPEED();  EA = 1;  RENUMERATE_UNCOND();  while(TRUE) {     for(i=0;i<512;i++){         EP6FIFOBUF = 0xee;     }     EP6BCH = 0x02;     SYNCDELAY;     EP6BCL = 0x00;     SYNCDELAY; }

Whenever I try to read data from the endpoint, the FX2 always reports that there is no data available. How to fix this problem?

Thank you for your support!

Kind regards,
Peter

Good afternoon all,

Why we need INT0(PA0) and INT1(PA1) pins of cy7c68013a-56 pin? When we should use this pins?

Good afternoon all,

In our project we are using one cypress board(56pin breakout board) with FPGA(spartan 3AN). We should interface cypress with FPGA board. For this we refered AN61345 and AN63620 application note from cypress. We downloaded sample code mentioned in AN61345 application note.

After we program cypress board by using slave.hex file and slavefifo.bit file to FPGA, How to see the output of this two code?

 Good morning all,

I want to download the USB control center utility software which is given in application note of AN61345(pg-10). Please go through the below attached document.

So, can you please send me the link where i will get this software?

Thank you,

Regards

 Good morning all,

We go through the EZ-USB contents and tutorials document, in that they have given(pg-10) about EZ-USB Control panel application. We follow the steps given in that page, but in start->peogram->cypress-> usb we not finding ez-usb control panel application.

So, Can you please tell me where we will get this one? Or send me the link to download this application.

 Hi, I like to turn on RTS/CTS hardware flow control for the CY7C64225 device, but can't find any document that shows me which register to change. Please help... thanks!
