Some modules contain external RF switch controlled by pins. This function gives RadioLib control over those pins to automatically switch between various modes: When idle both pins will be LOW, during TX the `txEn` pin will be HIGH, during RX the `rxPin` will be HIGH.

Radiolib will automatically set the pin mode and value of these pins, so do not control them from the sketch.

When more than two pins or more control over the output values are needed, use the setRfSwitchTable() function.

Parameters

  rxEn | RX enable pin.
  txEn | TX enable pin.

## ◆ setRfSwitchTable()

void RF69::setRfSwitchTable | ( | const uint32_t(&) | pins[Module::RFSWITCH_MAX_PINS],
|  | const Module::RfSwitchMode_t | table[]
| ) |  |

Some modules contain external RF switch controlled by pins. This function gives RadioLib control over those pins to automatically switch between various modes.

Radiolib will automatically set the pin mode and value of these pins, so do not control them from the sketch.

Parameters

  pins | A reference to an array of pins to control. This should always be an array of 3 elements. If you need less pins, use RADIOLIB_NC for the unused elements.
  table | A reference to an array of pin values to use for each supported mode. Each element is an RfSwitchMode_T struct that lists the mode for which it applies and the values for each of the pins passed in the pins argument respectively.

The `pins` array will be copied into the Module object, so the original array can be deallocated after this call. However, a reference to the `table` array will be stored, so that array must remain valid as long RadioLib is being used.

The `mode` field in each table row should normally use any of the `MODE_*` constants from the Module::OpMode_t enum. However, some radios support additional modes and will define their own OpMode_t enum.

The length of the table is variable (to support radios that add additional modes), so the table must always be terminated with the special END_OF_MODE_TABLE value.

Normally all modes should be listed in the table, but for some radios, modes can be omitted to indicate they are not supported (e.g. when a radio has a high power and low power TX mode but external circuitry only supports low power). If applicable, this is documented in the radio class itself.

#### Example

For example, on a board that has an RF switch with an enable pin connected to PA0 and a TX/RX select pin connected to PA1:

// In global scope, define the pin array and mode table
static const uint32_t rfswitch_pins[] =
{PA0, PA1, RADIOLIB_NC};
static const Module::RfSwitchMode_t rfswitch_table[] = {
{Module::MODE_IDLE, {LOW, LOW}},
{Module::MODE_RX, {HIGH, LOW}},
{Module::MODE_TX, {HIGH, HIGH}},
Module::END_OF_MODE_TABLE,
};
void setup() {
...
// Then somewhere in setup, pass them to radiolib
radio.setRfSwitchTable(rfswitch_pins, rfswitch_table);
...
}
