Hi,

 

I have uploaded a class library for interfacing the Nordic semiconductor NRF24L01P radio module. It is available at https://mfnordic.codeplex.com/ in source code form.

 

Some documentation has been posted on my blog http://corememorydum...n-codeplex.html

 

Its a pretty easy library to use so I hope that its easy for someone to pick up and use.

Hi Derek,

Thank you very much for sharing this driver with us!

What kind of projects are you building with your RF transceiver? Are you doing point-to-point wireless?

Out of curiosity: what made the Nordic RF chip the best pick for what you're doing (vs. XBee or another radio)?

Hi Chris,

 

I used this lib as part of a simple home monitoring system see the other post. Its using the radio device to do many to 1 half duplex transmissions.

 

I decided on using the Nordic nrf24l01P for a number of reasons

• Cost, the radio modules can be purchased for less than a euro most other RF is multiples of this price
• Space, other options use up a lot of board space
• Protocol, the device has a more functional protocol than some of the other ISM band radio's available
• Power the power consumption is low

One of the down sides is the 2.4 GHz carrier which attenuates more than ISM band frequencies indoors and in wet weather. But for the distances I am operating at ts not an issue.

Hi,

 

For anyone who might be interested I have updated this code. It is available here https://mfnordic.cod.../146477?lc=1033

 

This version reduces the LOC from 263 to 200 while adding additional features.
