# Third-party notices

This tool incorporates findings from the work below. Its licence notice is
reproduced in full as that licence requires.

## ClearTablet, by catears124

Used in this tool:

- the four analog settle immediates at `0x08004d3c`, `0x08004d4a`,
  `0x08004d58` and `0x08004d9a`
- the filter-bypass site at `0x0800760e` (`7c48` to `dbe0`)
- the redundant barrel-rescan sites at `0x08007e58` and `0x08007ed8`
- the substitution table used to decode GAOMON's obfuscated firmware updates,
  used here to cross-check a dump

Not from that work, and original to this project: the drive-burst finding and
its twelve patch sites, the timing decomposition and rate model, the 72 MHz
derivation, the tracker and dispatch analysis, the DFU transport, the
measurement tooling and this flasher.
