Hello!
I have a question:I developed interface with CY7C64713 -56 pin.I ordered delivery processor
by Farnell.Farnell delivered CY7C68013-56 pin.microcontroller.Can I replace them?
Thank you!

Show LessHi, god.
I met a problem with devices of cy7c68013a-100axc and 24lc32.
I wrote a firmware and got two formats: .hex and .iic. After xxx.hex loaded into the RAM, the usb renumerated and worked well. I think the firmware is right. But when I loaded the xxx.iic into the eeprom, the usb can't renumerate.
I assure xxx.iic was loaded into eeprom and the format is right. The first byte is 0xC2.
I don't know whether the program in eeprom wasn't loaded into RAM or loaded but not renumerated.
God, please tell me how to solve it! Thx.
Show LessI will try this out shortly, but want to know if support the the (USB2UART) chip in the subject line is supported in the standard USB "serial" devices yet.
Thanks, in advance,
Brendan
Show LessHi
i have problem that it's seem like power.
When i working fx2lp board and fpga board.
So i connect with both board for slave fifo working.
Fx2lp board is just connected USB cable( it's just use power from usb cable).
When i connect FPGA Board to Fx2lp board, FPGA Board's led is weak on.
it's seem like something wrong. but slave fifo is working well(stream project ).
I dont know what am i check ?
Show LessI am using a FX2LP that sets endpoint 6 to IN. The data is coming from an FPGA connected to the FIFOs of the FX2LP. Is there a way to determine when the host sends an IN packet to request data. I want to know this as I am using a feedback endpoint and want to return the count when the host requests it.
Thanks

Show LessI am using a cy68013. How can I configure the controller to work in high speed mode?. I have read in the datasheet that,at the first negotiations between host and the device, hosta asks whether the device is capable of high speed data transfer. does it mean if the device says it is capable, host will transfer data in high speed mode?
Show LessHello Cypress Developers Team,
I found a bug in the file i2c_rw.c which contains the I2C read and write functions used by the framework users.
The functions
BOOL EZUSB_ReadI2C(BYTE addr, BYTE length, BYTE xdata *dat)
BOOL EZUSB_WriteI2C(BYTE addr, BYTE length, BYTE xdata *dat)
return an "I2C status byte" defined in lp.h which looks like "I2C_OK".
However, the defined return value in the function is defined as BOOL thus the "I2C status byte" is cast to BOOL and loses its information. And worst of all EVERY return value of the functions casts to TRUE!
The return value could simply be defined as int or similar to keep the "I2C status byte" information.
I know I can fix the bug locally in my repository but the framework should be fixed too in my opinion.
Regards,
Robin
Show LessI have a FX2LP design with a set of descriptors to create a USB audio device. The device implements a speaker, so I have a USB streaming input and a speaker output. The device is recognised by Windows as a USB audio device. However when I open media player and play an mp3 I dont get any data coming out of the FX2LP. I should mention that the FX2 is connected to an FPGA. I have a program monitoring the data coming into the FPGA, but nothing happens. Does anyone have any thoughts? I have attached the file if anyone can see any problems.
Thanks
Jon
