There are lots of online examples on how to use that platform. Either way, it works if you set it up this way. There are many ways to set up the CYRF Links to my other pages: If you want an easy datasueet use solution and don’t mind being somewhat tied by the manufacturer’s design choices you might want to consider the Xbee.

The recommended value shown is configured for reliability rather than speed. One of the things i found intimidating when initially starting with these modules was getting an initial working config from which to start tweaking. The guys at http: The examples shown here presume Transaction Mode is switched off. There are a few hidden costs ctrf6936 using these modules.

I have a copy of the Datasheet that gives you all the register descriptions but at the moment the one on the Cypress website only gives the a list of the register names. My project uses Atmel AVR atmega microcontrollers for this. At the time of writing there does not appear to be a full datasheet available for the CYRF 7 that documents the configuration registers. Incoming data will cause the CYRF interrupt pin to trigger. RXGO should only need set when receiving data.

CYRF6936 Datasheet

Pins 11 and 12 on the ccyrf6936 are outputs of the RF switch status so it is important not to set the logic of these pins. Either poll this function often to detect incoming data or run it once when the CYRF interrupt pin triggers.


At the time of writing there is very little documentation online about interfacing the various CYRF based RF modules. It is widely cryf6936 in a huge range of commercial applications but largely unused by hobbyists at the time of writing. In theory any microcontroller of operating at 2. These have built in SPI hardware and more than enough program space for my application.

The CYRF has no control over this so it must be done in firmware by the microcontroller. Here i will simply list a working configuration and briefly touch on a few of the aspects a hobbyist may want to change. If this changes over time please let me know so i can update this section. Sb, 21mar11 3 this datasheet is subject to change without notice.

Existing documentation on the Datasheef This actually transmits the data and tests for successful transmission. Returns “1” if TX errors occurred.

This function returns “0” if data has been successfully received. Modules discussed on this page.

While it was worth cyrd6936 these the only really useful part are the header files for the pin definitions. Load transmit buffer with data. It cygf6936 suggested you use these as an initial working config from which you can experiment with making changes later. The AWA24S for example requires the microcontroller to stitch on and off the RF switch on the module using header pins on the module so it does not support Transaction Mode.

This automated the reply of an ACK packet whenever a module receives a packet. Silan semiconductors scab hangzhou silan microelectronics jointstock co. The PA setting you will probably want to set to it’s highest power. The Unigen datasheet does not mention this. datashfet

Set various Transmit functions here. You will need to go to the Technical Reference Manual for the register descriptions.

Not really needed as the rest of this setup does not use chip correlators. The CYRF transmit buffer is only 16 bytes daatasheet so we will only be discussing transmissions up to this length. Set your microcontroller to input if it is connected to these pins. Cyrf datasheet, cyrf circuit, cyrf data sheet.

I am writing this page in the absence of any other resource for hobbyists to use this highly useful, high speed 2. I suspect there is a misconfiguration in our clock setup and datashset RXGO gets the clock running correctly.

The transmitting module listens for this ACK and only reports a successful transmission if it is received. Returns “0” if TX was successful. If you have success with any other modules please let me know. The CYRF can be used to add wireless radio communication to most modern eatasheet. Every time you cjrf6936 into problems read it again.

This register controls some of the built in receive circuitry. Artaflex does a reasonable job of documenting any important details that may be different from default when configuring the CYRF in their modules. Here are the ones i have experimented with:
