Functions

uint8_t RegionCommonValueInRange (int8_t value, int8_t min, int8_t max)
 Verifies, if a value is in a given range. This is a generic function and valid for all regions. More...
 
bool RegionCommonChanVerifyDr (uint8_t nbChannels, uint16_t *channelsMask, int8_t dr, int8_t minDr, int8_t maxDr, ChannelParams_t *channels)
 Verifies, if a datarate is available on an active channel. This is a generic function and valid for all regions. More...
 
bool RegionCommonChanDisable (uint16_t *channelsMask, uint8_t id, uint8_t maxChannels)
 Disables a channel in a given channels mask. This is a generic function and valid for all regions. More...
 
uint8_t RegionCommonCountChannels (uint16_t *channelsMask, uint8_t startIdx, uint8_t stopIdx)
 Counts the number of active channels in a given channels mask. This is a generic function and valid for all regions. More...
 
void RegionCommonChanMaskCopy (uint16_t *channelsMaskDest, uint16_t *channelsMaskSrc, uint8_t len)
 Copy a channels mask. This is a generic function and valid for all regions. More...
 
void RegionCommonSetBandTxDone (Band_t *band, TimerTime_t lastTxAirTime, bool joined, SysTime_t elapsedTimeSinceStartup)
 Sets the last tx done property. This is a generic function and valid for all regions. More...
 
TimerTime_t RegionCommonUpdateBandTimeOff (bool joined, Band_t *bands, uint8_t nbBands, bool dutyCycleEnabled, bool lastTxIsJoinRequest, SysTime_t elapsedTimeSinceStartup, TimerTime_t expectedTimeOnAir)
