B4R Question Is a Library for the Nordic nRF24L01+ 2.4GHz RF transceiver planned?

[rwblinn]

Hi,

are there plans to build a library to support the Nordic nRF24L01+ 2.4GHz RF transceiver?
(like descibed here).

Appreciated

It would be very nice to have such a library, but before SPI library should be implemented.

Does this product include everything needed to use this chip: http://www.ebay.com/itm/2pcs-NRF24L...242450?hash=item1c544a5752:g:Q8gAAOSwpDdVdl6~ ?

Hi Erel, what you show is a converter from I2C to SPI for the nRF24L01 modules (not include). The real modules are like this ones http://www.ebay.com/itm/5pcs-NRF24L...965820?hash=item2ee5447a3c:g:gUQAAOSwLa9UXJmy
and they use SPI protocol. They are powered at 3.3V but inputs pins are 5V tolerant.

Many tutorials are available online like this one: http://randomnerdtutorials.com/nrf24l01-2-4ghz-rf-transceiver-module-with-arduino/

A very detailed tutorial can be found here: www.diyembedded.com/tutorials/nrf24l01_0/nrf24l01_tutorial_0

After looking at it more closely, it seems that the SPI library do not need to be explicitely wrapped to be used. The rEthernet library is using SPI.

I will take some time this weekend to try the library creation process.

Toley, I hope your able to create an SPI library. A SPI library will help connect to many different devices without having to create specific libraries for each device
