%% Routine Data Transmission Functionality

and convert to Mavlink bytes"]
packHPBuffer["Pack drone state data
(Mavlink bytes) into
GSC.highPriorityTransmitBuffer"]

contents via GSC.transmit()"]

%% DMA Receive Functionality
DMAInterrupt("RFD900 Interrupt: receiveInterruptServiceRoutine")
receiveData["Receive data"]
checkBufferSpace{"GSC.DMAReceiveBuffer
enough space?"}
addDataToBuffer["Add new data to GSC.DMAReceiveBuffer"]

%% Loop Update Functionality

(to callback actions) from
