33 * \brief Thermo-control driver.
35 * This module implements multiple thermo controls, which is the logic needed to try
36 * keeping the temperature of a device constant. For this module, a "device" is a black box
37 * whose temperature can be measured, and which has a mean to make it hotter or colder.
38 * For instance, a device could be the combination of a NTC (analog temperature reader) and
39 * a Peltier connected to the same physic block.
41 * This module relies on a low-level driver to communicate with the device (implementation
42 * of the black box). This low-level driver also controls the units in which the temperature
43 * is expressed: thermo control treats it just as a number.
