 * \brief      SX1276 RF chip high level functions driver
 *
 * \remark     Optional support functions.
 *             These functions are defined only to easy the change of the
 *             parameters.
 *             For a final firmware the radio parameters will be known so
 *             there is no need to support all possible parameters.
 *             Removing these functions will greatly reduce the final firmware
 *             size.
