HID Over I2C Protocol Specification: Host side? RRS feed

  • Question

  • Hello

    You have posted a a HID Over I2C Protocol Specification for the device side here: 

    I am wondering if you know of any HID Over I2C Protocol Specifications for the Host side (or have any plans to write it)?

    I am specifically wondering about whether or not the Host/Master side will/should retry to send the first byte (start condition (s) + 7 bit address + R/W bit) if the device/slave does not respond with an ACK on this first transmitted byte (host retry).

  • That detail is likely to be in the I2C bus protocol specification. The host I2C controller is expected to follow the I2C bus protocol rules.
