✨ TCTI-SPI(7) ✨

okay bestie, welcome to the Miscellaneous Information Manual section — yes that's the manual name, we're fancy now 💅

---

💖 NAME 💖

tcti-spi-ftdi — the USB to SPI-based TPM TCTI library, and she is thriving

---

🌸 SYNOPSIS 🌸

So basically? It's a TPM Command Transmission Interface (TCTI) module. Her whole job is talking to a SPI-based TPM, and she gets there by going through the FTDI MPSSE USB to SPI bridge. Middle-man energy, but make it iconic. 🦋

---

✨ DESCRIPTION ✨

tcti-spi-ftdi is a library that abstracts the details of communication with a SPI-based TPM over the FTDI MPSSE USB to SPI bridge. Like, she handles all the messy parts so you don't have to, no cap.

The interface she exposes is defined in the “TSS System Level API and and TPM Command Transmission Interface Specification” specification. (Yes, the double "and and" is in the original name of the spec. Not me. Not my typo. We're keeping it exactly as it is because the facts do not change, periodt. 😭)
