Hi,
We don't understand the basics.
Please tell us about cy7c65216.
Is it possible to configure a circuit that connects multiple slave devices with different slave addresses using cy7c65216 as the master?
Is it possible to read and write any number of bytes of data from any address using the software provided by your company?
Is it correct to understand that the read and write waveforms are as shown in the figure below?

Are there any other related documents or materials other than those listed in the "More Information" section of the datasheet?
Regards,

Hi,

what is meant by arm EP2OUT ?

what does the below code does ?

EP2BCL = 0x80; // Re-arm endpoint 2

Thankyou

Hi,

Under Linux system, how to

1. Confgiure CY7C65215 with programming new setting in Linux? like "USB-Serial Configuration Utility" in Windows or fwDownload.exe in command line.

2. In Linux, after re-porgramming CY7C65215 with new setting, how to enable new setting? Softare Reset or power cycle?

3. Is there document to teach customers how to use about item 1 and 2?

Regards,

Kyle

Hello, please tell me a question. If we connect multiple CYUSB3014 devices to the PC and open them at the same time, how can we set the bulkEndpoint for each device at this time, because from the existing routine, I see that bulkEndpoints are all obtained through ccyUSBDevice, and ccyUSBDevice is only instantiated once

hi,

i have wrote a simple to code to access the esp8266 via I2C.

bilnk led and i2c_write ; LOOP

when the SDL is not connected to the ESP8266,the loop repeats (led blinks and I can see the SCL and SDA in logic analyzer).

the moment i connect the SDL line to the ESP8266, the code hung up.

Note ;

1. The connections are correct .

2. The FX2 kit has pull up (2.2K)resistors on both SCL and SDA line.

3. SDCC compiler is used.

Please suggest ways to resolve or debug.

Thank you.

Hi,

My customer wants to know if he can see two devices in Linux system when CY7C65215 is configured as SPI and I2C on the two channels.

Hi!

Following the CyUSB.NET.pdf file (2018, according to this is the lastest version https://community.infineon.com/t5/USB-superspeed-peripherals/CyUSB-NET-manual/td-p/105011) of the FX3 SDK , how can I program the EEPROM of a FX3/CX3 with my C# code?

Should I use this function?

"4.9.1 DownloadFw( )

Description

The DownloadFw method of CyFX3Device allows the user to download firmware to various media such
as RAM,I2C E2PROM and SPI FLASH.

The file name of the firmware file is passed as the first parameter to the API. The file must be a *.img
to keep this operation from failing."

Thank you!

Hi,

Despite what it says on the KB page ( https://community.infineon.com/t5/Knowledge-Base-Articles/Mouse-Sample-Firmware-for-CY7C63001A-PC/ta-p/257171 ) the support team doenst have this data any more, or doesnt want to share it.  So I am looking out there with people to obtain this firmware samples, does anyone have it ?

Cheers,
