2 * @file tunerstudio.cpp
3 * @brief Binary protocol implementation
4 *
5 * This implementation would not happen without the documentation
6 * provided by Jon Zeeff (jon@zeeff.com)
7 *
8 *
9 * @brief Integration with EFI Analytics Tuner Studio software
10 *
11 * Tuner Studio has a really simple protocol, a minimal implementation
12 * capable of displaying current engine state on the gauges would
13 * require only two commands: queryCommand and ochGetCommand
14 *
15 * queryCommand:
16 * Communication initialization command. TunerStudio sends a single byte H
17 * ECU response:
18 * One of the known ECU id strings.
19 *
20 * ochGetCommand:
21 * Request for output channels state.TunerStudio sends a single byte O
22 * ECU response:
23 * A snapshot of output channels as described in [OutputChannels] section of the .ini file
24 * The length of this block is 'ochBlockSize' property of the .ini file
25 *
26 * These two commands are enough to get working gauges. In order to start configuring the ECU using
27 * tuner studio, three more commands should be implemented:
28 *
