Round requested sleep time up to next multiple of 16ms, to sleep at
least requested time.
Sleep time of 0 will return immediately.
Fixed watchdog sleep time calculation. AVR libc watchdog time
implementation is inconsistent, and requires larger flash/ram usage.
* Add critical section support
Allows defining a code block which is executed as a critical section.
Supports AVR, ESP8266 & SAMD.
* Add receive message buffering
When MY_RF24_IRQ_PIN is defined (and connected), a buffer will be used
to retrieve & store messages received by nRF24 as fast as possible.
This reduces the chance of losing messages due to a busy
microcontroller.
nRF24 SPI rx message transfer is running from interrupt context when
MY_RF24_IRQ_PIN is defined. If this transfer takes too long, serial
characters received will get lost. Therefore serial rx is enabled during
SPI transfer of nRF messages.
Limitations: Only AVR/SAMD & nRF24L01+ combinations can buffer rx
messages.
nRF24L01+ IRQ pin should be connected to AVR.
Tested on W5100- & Serial-gateway.
SAMD has not been tested yet!
