Changes: - Enable PTX at radio begin, in standby-I mode - Enable PTX at radio stopListening(); in standy-I mode - Radio startListening - removed delay. What is there to wait for when the radio will just be listening anyway? - Radio powerUp - radio will need to be powered up after configuration - radio will not power down unless instructed to - need to issue radio.txStandBy(); when finished transmitting to engage standby-I mode - Added txStandBy() to drop to standBy-I mode if not switching to RX mode - Radio Write: Sped up - radio previously did not use standby mode effectively, after TX sending of each packet, the radio is powered down introducing a 1.5ms delay in addition to the 130us delay from standby. - No observe-tx code, a simple NOP cmd is sent to get the status info - No millis() timeout, hanging condition should only occur because of faulty code - Simplified whatHappened() code - Flush TX FIFO if MAX_RT met as lib does not support re-transmit instead of flush every time. - Remove ack size monitoring - No powerdown needed, - Added writeClear() function for writes that need the interrupt flags cleared (ack payloads, etc). Same as write() otherwise - Radio startWrite: Sped up - Enable PTX mode is now done in stopListening() code. Enter TX mode by writing CE high. This brings the data transfer capabilities up to a reasonable level - No need to power up, already in Standby-I mode - No need for delayMicroseconds() in write functon. - No need for delay after writing CE high - Does not enter Standby-I mode be default. It is up to the MCU to call the new txStandBy() function to enter standby-I mode from PTX if not switching back to PRX - Radio available: - Now checks the FIFO buffer instead of the interrupt flag (no missed data) - Moved clearing of interrupt flags to Read() - Radio read: - No longer returns any value - use available to check for more data - Radio isAckPayloadAvailable() now checks the FIFO directly - Radio getDynamicPayloadSize() - Per the datasheet, added fix to flush corrupted packets
Arduino driver for nRF24L01 2.4GHz Wireless Transceiver
Design Goals: This library is designed to be...
- Maximally compliant with the intended operation of the chip
- Easy for beginners to use
- Consumed with a public interface that's similiar to other Arduino standard libraries
- Built against the standard SPI library.
Please refer to:
This chip uses the SPI bus, plus two chip control pins. Remember that pin 10 must still remain an output, or the SPI hardware will go into 'slave' mode.
