USB low-full-high speed peripherals Forum Discussions

I want to install CyUSB Suite for Linux. But it failed when make.I do this as document said. Could somebody help me? Thanks.

I have designed a PCB for Cy7C65211 IC. In datasheet the default VID & PID is given and after connecting it to the PC the system throws error as "Device Descriptor Request failed" in the device manager. I tried to change the *.inf file, but need further assistance.

Hi,

I am searching for USB to UART/SPI/I2C converter, where i need UART and SPI at the same time.

I have found CY7C65215 have 2 different channels.

My Query is, shall I use one channel for UART, GPIOs & Another channel for SPI, GPIO's.

SCB0 as MODE 2 and SCB1 as MODE 4 at the same time?

Thaks & Regards

I want to use external SRAM for cy7c68013a-128pin(fx2).

Because firmware larger than the internal memory of EZ-USB.

How to connect PSEN, RD, WR, CS, OE, EA. and build option.

( I used SRAM CY7C199D-10ZXI.)

my build option

.\hex2bix -i -e -m 0x2000 -f 0xC2 -o filename.iic filename.hex

what is probrom?

We have confirmation about CY7C65213-32LTXI.

I am using "CYUSB 232 USB-UART LP REFERENCE DESIGN KIT" to ”comfirm for the operation.

BM option does not exist in USB - UART driver detailed setting.
Is it impossible to set the waiting time?

We would like to consider the BM mode in order to prevent the communication speed from becoming slow.

Hello,

fx2lp clock is having external  clock source as 24MHz,(not using crystal oscillator).but if i set CPUCS = 0x02; that is 12MHz,

if i do this,Is fx2lp clock reduced to 12MHz even its supplied with 24MHz?

or

its only effect on SYNCDELAY?

let me know.

regards,

Hello

I wonder if its is possible to make the CY7C68013A-56 load the EEPROM content from a microsontroller?

More explanation, the board loads the content from 24C256 via SDA SCL, is it possible to make it read that content from a microcontroller?

Thanks

Hello,

I am using usblyzer,i am able to capture the data,but every time data transfer from fx2lp to host is fixed to 4 bytes only(raw data).how to solve this?

i have attached the screenshot of usblyzer.please help me.

Hi all,

I am encountering a problem with  CY7C68013A.

Using the cyusb3.inf from driver for win7 (I am using win10) and adding custom PID/VID/Desc in .inf file, the device can be correctly recognized by windows device manager, Cypress control center and USB console. (The EEPROM is not connected by far.)

But, when I use control center to program the firmware (from bulkloop example) file .hex/.iic to RAM/EEPROM， the programming process looks fine, but after this point, the device can be recognized by device manager with new name, but can NOT be recognized by control center or USB console. In fact, control center and USB console freeze without any response. (or it takes more than 1 min to launch, and showing no device.)

And if I reset the 68013, control center and USB console can recover immediately, and recognize the device with the default PID/VID and device name.

What causes this problem?

Thanks and any help will be appreciated.

Best,

Zheng
