Hello,

I use latest version of cyusbserial.dll downloaded from http://www.cypress.com/documentation/software-and-drivers/usb-serial-software-development-kit

My currently working setup is Win10 x64 and 2 versions of cyusbserial.dll

Selected is I2C communication.

Writing and reading works!

Logic analyzer

BUG:
Reading function CyI2cRead() reads more bytes than desired.

With latest library it reads 8+desired (example. when I want to read 1 byte, it reads 9 bytes)

See attached .zip file for contents.

DIFF:
There seems to be the difference between library versions. Older library reads 2 bytes when reading 1byte

INFO:

For further explanation I am more than happy to elaborate.

Kind regards,

Ziga

i know Linux implementation is Open Source.

Don't have working Linux setup, so I don't have time to debug *.so what is going wrong.

Hello Ziga,

The CY7C65211A part is pin to pin compatible with the CY7C65211 part and can be used with the CYUSB234 DVK.

Best Regards,

Sananya
