walterluu 3:85fc843a9d7d 2 * This File is responsible for defining the buffers that will be used in
walterluu 3:85fc843a9d7d 3 * various areas of the program. The buffers that are defined here will be
walterluu 3:85fc843a9d7d 4 * refferenced in the main.cpp and will be filled with data in one of two ways:
walterluu 3:85fc843a9d7d 5 *
walterluu 3:85fc843a9d7d 6 * 1. The buffers will be filled with data upon receiving a successful payload
walterluu 3:85fc843a9d7d 7 * transmission over LoRa. In GenericPingPong.cpp, the function OnRxDone()
walterluu 3:85fc843a9d7d 8 * will call the function fillGlobalBufsWithPayload() that is responsible for
walterluu 3:85fc843a9d7d 9 * filling the appropriate buffers with the payload data that was received
walterluu 3:85fc843a9d7d 10 * by either the master or slave device by the other device that sent it.
walterluu 3:85fc843a9d7d 11 *
walterluu 3:85fc843a9d7d 12 * 2. The buffers will be used to fill up a payload buffer that will be sent
walterluu 3:85fc843a9d7d 13 * over LoRa by either the master or slave device to the receiving device.
walterluu 3:85fc843a9d7d 14 * The function fillPayloadWithGlobalBufs() will use the global buffers that
walterluu 3:85fc843a9d7d 15 * are filled with data for various sensors in the main.cpp to construct a
walterluu 3:85fc843a9d7d 16 * payload to deliver to the other device when SX1276PingPong() is called
walterluu 3:85fc843a9d7d 17 * in file GenericPingPong.cpp.
