nRF24L01+ 2.4 GHz Wireless Connectivity with the tinyK20 Board

Posted on March 13, 2016 by Erich Styger

I’m using the tiny and inexpensive Nordic Semiconductor nRF24L01+ transceiver (see “Tutorial: Nordic Semiconductor nRF24L01+ with the Freescale FRDM-K64F Board“) in many projects: it costs less than $3 and allows me to communicate with a proprietary 2.4GHz protocol in a low power way (see “IoT: FreeRTOS Down to the Micro Amps“). I have that transceiver now running with the tinyK20 board too:

McuOnEclipse Components: 27-Dec-2014 Release

Posted on December 30, 2014 by Erich Styger

This post is overdue, as it is about the McuOnEclipse components which have been released already a few days ago. The highlights are (beside smaller updates and bug fixes):

Nordic Semiconductor nRF24L01+ component extended for shared SPI bus usage
SD_Card component can use AsynchroSerial component for Kinetis
FatFS has added v0.10c patches
FSL_USB_Stack: Host support for Kinetis K20D72 and support for FRDM-K22F (K22FN512)
FreeRTOS has added Timer API support

NeoShield: WS2812 RGB LED Shield with DMA and nRF24L01+

Posted on November 10, 2014 by Erich Styger

In my earlier post I used a hacked together shield for building a clock based on Adafruit’s NeoPixel/WS2812 (“LED Clock with Kitchen Hot Pan Protector“). The new design supports now 8 parallel data streams, integrated realtime clock and wireless connectivity with the nRF24L01+ module.

Tutorial: Nordic Semiconductor nRF24L01+ with the Freescale FRDM-K64F Board

Posted on July 1, 2014 by Erich Styger

For some time I’m using the Nordic Semiconductor nRF24L01+ transceiver successfully in many projects (see “Tutorial: Ultra Low Cost 2.4 GHz Wireless Transceiver with the FRDM Board“). Since that tutorial things evolved a lot with the introduced RNet Stack. To honor the popularity of the Nordic Semiconductor nRF24L01+, Freescale has put a socket on the FRDM-K64F board. So time to make a new step-by-step tutorial how to use the nRF24L01+ with the FRDM-K64F.

Enhanced RNet Wireless Components and Communication Stack

Posted on May 11, 2014 by Erich Styger

I’m using both the Freescale MC1320x and Nordic Semiconductor nRF24L01+ 2.4GHz in many projects. To make it even easier to use these transceivers in the RNet stack, I have updated it with several new functions.
