Hello!

I am interested in connecting an I2C master to an I2C slave trough a wireless link! It is a fairly trough problem to me, becuse the Data Line (SDA) is bi-directional.The Master is CY764713, and Slave is a  hearing aids hybrid development by On Semiconductors!Distance wireless communication within 1 meter.

Thanks for the ideas!

 I ' m fresh. Now  I   am learning the   USB control chip, CYUSb 3014. The VIO2 supply  power  for IO2. Which part   is   the  IO2 power supply domain in the chip? Thanks for your reply.

 Hi, 

I am working on Cypress USB FX2LP controller (Cy7C68013A). I need to enable the external interrupt on INT0, as negative edge detecting. I had tried the following changes on bulkloop example on FX2LP. 

  PORTACFG = 0x03;            // PA0 and PA1 are INT0 and INT1

TCON |= 0x05;               // Detect INT0 and INT1 on fallinfg edge

IE  |= 0x05;    // Enable External Interrupts 0 and 1

After adding these lines in TD_Init() of the bulkloop example, the USB device was not getting enumerated by the EZ-USB Interface tool. 

Anyways, the enumeration works fine without these three lines of code in bulkloop example, and the device is detected as EZ-USB. 

What is wrong with the above code ? Is there anything more needed to be added to the enumeration to happen ? 

Thank You

With Regards

 Hello:

       I am tring to read data from AD using CY68013 and I don't know how many bytes that  it will return in a transmission. The method is Xferdata. the second parameter was set to 1024, which is bigger than actually bytes in the fifo. For example, at this moment, there are 512 bytes in the fifo, and  I use Xferdata to get those data. 

      But this method will return false, and the parameter, len, was set to 0. 

      Here is my question. if  i don't know how many bytes are in  the fifo, and I want to know how many bytes I got, what can I do?

thanks for your help.

Regards

I am new at Cypress and EZ-USB FX2LP, I need some help to programming the Vid/Pid in the boards EEPROM. I have a EZ-USB FX2LP board with the (ISSI 32K SRAM) I am trying to assign a new Vid/Pid to the board, and I am using the NX2LP Programmer Utility, but it doesn't work for me! I have read all the help file and other PDF files that I could find at Cypress, and I exactly did what are at the help files, but I had no luck!   

I can use the CyConsole EZ-USB  for Download *.iic and *.hex files, but when I try the NX2LP Programmer Utility it just not working, I really don't know what is wrong here! Any help will be most appreciate.

 Does anyone make applications that use CyUSB.sys and DIrectShow?

I want to make video application using standart driver CyUSB.sys and videoout throught DirectShow

Thanks

 Hi 

My fx2lp is Slavefifo with fpga and sensor. 

Fx2lp out  garbage data (all 0)  when sensor's hsync is low. 

How am i supposed to handle these problem?

Can i use hsync instead for slwr?
