38 * @brief API to common functions of MRAA
40 * This file defines the interface for libmraa common functions
46 * Detects running platform and attempts to use included pinmap, this is run on
47 * module/library init/load but is handy to rerun to check board initialised
48 * correctly. MRAA_SUCCESS inidicates correct (first time) initialisation
49 * whilst MRAA_ERROR_PLATFORM_ALREADY_INITIALISED indicates the board is
50 * already initialised correctly
52 * @return Result of operation
61 * Get libmraa version.
63 * @return libmraa version (e.g. v0.4.0-20-gb408207)
68 std::string ret = mraa_get_version();
73 * This function attempts to set the mraa process to a given priority and the
74 * scheduler to SCHED_RR. Highest * priority is typically 99 and minimum is 0.
75 * This function * will set to MAX if * priority is > MAX. Function will return
78 * @param priority Value from typically 0 to 99
79 * @return The priority value set
82 setPriority(const unsigned int priority)

88 * Get platform type, board must be initialised.

101 * @param result the result to print
104 printError(mraa_result_t result)

110 * Checks if a pin is able to use the passed in mode.
112 * @param pin Physical Pin to be checked.
113 * @param mode the mode to be tested.
114 * @return boolean if the mode is supported, 0=false.

136 * @return return actual bit size the adc value should be understood as.

145 * Return Platform Name. Returns NULL if no platform inited.
