# [NAME](#NAME)

tcti-i2c-helper - device driver TCTI library

# [SYNOPSIS](#SYNOPSIS)

A TPM Command Transmission Interface (TCTI) module for communication via I2C. TPM device driver.

# [DESCRIPTION](#DESCRIPTION)

tcti-i2c-helper is a library that abstracts the details of communication with a TPM via I2C protocol. It uses user supplied methods for I2C and timing operations in order to be platform independent. These methods are supplied to \`Tss2\_Tcti\_I2c\_Helper\_Init\` via the \`TSS2\_TCTI\_I2C\_HELPER\_PLATFORM\` struct.
