Detailed Description

macros for customization of RF24Audio

Macro Definition Documentation

buffSize

#define buffSize   32

The size of the memory buffer to use.

Not really configurable (set to maximum by default).

ENABLE_LED

#define ENABLE_LED

Indicator pin.

Using pin 6 on Uno enables audio visualization. Pin 13 on Mega 2560 (TIMER0 COMPA)

Note

The pin number cannot be changed.

RF_SPEED

#define RF_SPEED   RF24_1MBPS

configure the RF data rate

These are not limits, just a guide:

• RF24_250KBPS will do 13-20khz+ sample rate
• RF24_1MBPS up to 24-44khz+
• RF24_2MBPS for higher.

SAMPLE_RATE

#define SAMPLE_RATE   24000

The sample rate to use for transferring audio samples.

Maximum Range: Sample rate 16000, RF_SPEED RF24_250KBPS
Maximum Quality: Sample rate 44000, RF_SPEED RF24_2MBPS

Note

44khz+ sample rate requires 8-bits per sample
