In the following excerpt of the file RFM69.cpp,
Please explain the last line two lines to me? It looks like a 2 dimension array "CONFIG", with the first element of the first index being "REG_OPMODE", and the second element being..., well, I don't understand the "RF_OPMODE_SEQUENCER_ON | RF_OPMODE_LISTEN_OFF | RF_OPMODE_STANDBY".
The arguments (constants) are defined in RFM69registers.h;
#define RF_OPMODE_SEQUENCER_OFF 0x80
#define RF_OPMODE_LISTEN_OFF 0x00
#define RF_OPMODE_STANDBY 0x04.
Is it as simple as these three constants being OR'd together?
excerpt-
bool RFM69::initialize(uint8_t freqBand, uint16_t nodeID, uint8_t networkID) {
_interruptNum = digitalPinToInterrupt(_interruptPin);
if (_interruptNum == (uint8_t)NOT_AN_INTERRUPT) return false;
[b]const uint8_t CONFIG[][2] = {
/* 0x01 */ { REG_OPMODE, RF_OPMODE_SEQUENCER_ON | RF_OPMODE_LISTEN_OFF | RF_OPMODE_STANDBY },[/b]
yes logical OR
