hi, I am trying to connect Renesas skp16c62p microcontroller to rf-24G transceiver to do back to back testing. I check the datasheet of rf-24g but can not figure out how to interface them. if I use shockburst mode, there are three pins are needed in Tx side. How should I connect the CLK1 to the microcontroller, any pin is OK? and also how about the CE, can I simply use any pin on micro to control the CE? Besides, another question is how I can clock the address and payload to the Rf-24G. The sample code is about PIC, I am not so clear of this micro. I am a beginner of RF-24G. Thanks fpr your reples. ---

Any generic i/o pin is ok yes. If your MCU can do SPI then that is also an option (SPI hardware controls data and CLK1 in this case - you still have to control CS and CE). When receiving you also need to monitor the DR1 pin. Read here about SPI connection: [http://www.nordicsemi.no/files/Product/ … RF2401.pdf](http://www.nordicsemi.no/files/Product/white_paper/Interface_SPI_nRF2401.pdf) Some example code using SPI (not for your MCU but it is in C) is in the AVR Code forum. /Lars ---

Hi thanks, My MCU does not support spi fucntion. But it support serial comms. I want to connect it to RF-24G with UART. When MCU load ADDR and payload to the RF-24G, which pin do I need to use? CLK1 or DATA? How can I provide a clocking signal to RF-24G? Is it via CLK1? > Lajon: > Any generic i/o pin is ok yes.

spi is very easy to do in software. there are many many examples available from your friend google. ---

They do SPI using the UART in the sample code available here: [http://america.renesas.com/fmwk.jsp?cnt … skp16c62p/](http://america.renesas.com/fmwk.jsp?cnt=skp16c62p.jsp&fp=/products/tools/introductory_evaluation_tools/starterkits_evaluation_boards/skp/skp16c62p/) /Lars
