    USB TO I2C Situation Concern

    yhmcjc_1432341

      About CY7C65215

         

      1.Does the driver for this chip has an armv6 version? arm-linux-gcc?

         

      2. I wanna know its performance when using as i2c master? When i need to send a block of bytes, will this chip have a big delay between two bytes causing by read the ack back to cpu and let cpu decide if the transmission is correct? This will waste a lot of time.

         

      3. Does this chip support multi thread? if i call a function to write sth, two write function can be called simultaneously without mutex? As this function utilizes one usb, so i have a concern about that

         

       

         

       

         

      Thanks

          Hi

             

          1.Does the driver for this chip has an armv6 version? arm-linux-gcc?

             

          >> You can find the drivers available for the part in the link: http://www.cypress.com/documentation/software-and-drivers/usb-serial-software-development-kit 

             

          2. I wanna know its performance when using as i2c master? When i need to send a block of bytes, will this chip have a big delay between two bytes causing by read the ack back to cpu and let cpu decide if the transmission is correct? This will waste a lot of time.

             

          >> There will not be big delay between two bytes when you send/receive blocks of data.

             

          3. Does this chip support multi thread? if i call a function to write sth, two write function can be called simultaneously without mutex? As this function utilizes one usb, so i have a concern about that

             

          >> Although, the part utilizes one USB, you can perform two simultaneous writes as the endpoints associated to channels are different.
