For nRF24L01+ to go from power down mode to TX or RX mode it must first
pass through stand-by mode.
There must be a delay of Tpd2stby (see Table 16.) after the nRF24L01+
leaves power down mode before
the CEis set high.
5ms is the maximum defined in the v1.0 datasheet
- Added new function: enableDynamicAck() to enable single-write NOACK
payloads (merge closer with gcopeland fork)
- Added single NOACK writes for write(), writeFast(), startWrite() and
startFastWrite()
- powerUp() now checks to see if radio is powered on. No delay if
powered up.
- radio must still be powered up manually if powered down manually
- use setRetries function in begin()
- set CE low on powerDown
- updated readme
Found that Due would send multiple payloads or fail in writing in some
cases. Change ensures single-payload transmission using write().
- Updated pingpair_dyn.ino example sketch to conform with available()
changes
- Slight doc update
- Tested and now fully functional on Arduino Due
- Added support for the extended SPI functions: brings Due performance
up to par with Due managing the CSN pin and settings
- Corrected issues with printDetails() on Due
- Changed added variables to staticly defined types: ie: uint16_t
instead of unsigned int
- I think this will work on all ARM based boards that use the Arduino
libs
- Added maskIRQ function - to be used in RF24Network sleep mode
- Changed csn(int mode) to csn(bool mode)
- Updated GettingStarted_CallResponse.ino example: Capture start time
AFTER printing to serial so measurement is more accurate
- Found I could create a hang condition on startup with some code.
a: Now power up the radio on begin() to simplify things
b: Increase delay to 5ms for powerUp, although it should only take 2ms
tops, this prevents the hanging condition.
- Initial support for Due and ATTiny boards
- Fix for 0 timeout period causing hang
- Remove unnecessary delays from startWrite
- Cleaned up/Updated example files
- Optimization is nearing completion
- For use in noisy or low signal scenarios
- Allows user specified timeout period of extended duration
- Modified txStandBy() and writeBlocking() functions to rely on a user
defined timeout period, automatic retries and payload reUse
txStandBy() now either works in two modes. The main mode will block
until success or fail. Using txStandBy(1) will block and retry forever
until succesful. Using a while loop with the function is no longer
required. See the updated class reference at
http://tmrh20.github.io/RF24/class_r_f24.html
Added back original startWrite function for when users want to use
manual methods. The library uses startFastWrite for its internal
functions. Provides compatibility with prev. code while still using the
new methods for everything else.
- txStandBy was hanging if the last of the data timed out. Now clears
the MAX_RT flag if timed out
- Finished updating example file Transfer.ino for demonstrating
half-rate transfers using the FIFO buffers
