Revision:
23:f74a50977593
Child:
24:e8d03912f303
I added file global_buffers.h and also reworked a portion of the main.cpp to adjust to the new method of using global buffers defined in a different file.

Who changed what in which revision?

dev_alexander 23:f74a50977593 2 * This File is responsible for defining the buffers that will be used in
dev_alexander 23:f74a50977593 3 * various areas of the program. The buffers that are defined here will be
dev_alexander 23:f74a50977593 4 * refferenced in the main.cpp and will be filled with data in one of two ways:
dev_alexander 23:f74a50977593 5 *
dev_alexander 23:f74a50977593 6 * 1. The buffers will be filled with data upon receiving a successful payload
dev_alexander 23:f74a50977593 7 * transmission over LoRa. In GenericPingPong.cpp, the function OnRxDone()
dev_alexander 23:f74a50977593 8 * will call the function fillGlobalBufsWithPayload() that is responsible for
dev_alexander 23:f74a50977593 9 * filling the appropriate buffers with the payload data that was received
dev_alexander 23:f74a50977593 10 * by either the master or slave device by the other device that sent it.
dev_alexander 23:f74a50977593 11 *
dev_alexander 23:f74a50977593 12 * 2. The buffers will be used to fill up a payload buffer that will be sent
dev_alexander 23:f74a50977593 13 * over LoRa by either the master or slave device to the receiving device.
dev_alexander 23:f74a50977593 14 * The function fillPayloadWithGlobalBufs() will use the global buffers that
dev_alexander 23:f74a50977593 15 * are filled with data for various sensors in the main.cpp to construct a
dev_alexander 23:f74a50977593 16 * payload to deliver to the other device when SX1276PingPong() is called
dev_alexander 23:f74a50977593 17 * in file GenericPingPong.cpp.
