1 /*
2 * This utility reads an RF parameter table of one of the supported types
3 * in FreeCalypso ASCII format (it has to be one of the tables that go
4 * into the T_RF_BAND structure) and converts it into a C code snippet
5 * suitable for insertion into the firmware source in the L1 RF "customization"
6 * code where compiled-in default RF parameter tables are defined.
7 *
8 * This tool is primarily intended for use with tx-ramps tables and maybe
9 * tx-levels, but it also supports tx-calchan, tx-caltemp, rx-agc-params,
10 * rx-calchan and rx-caltemp tables.
11 *
12 * This program is based on the calextract tool from 2014 (freecalypso-reveng
13 * repository) and the generated C code snippets feature the same style,
14 * indentation and comments.
