It is widely used in a huge range of commercial applications but largely unused by hobbyists at the time of writing.

The recommended value shown is configured for reliability rather than speed. Every time you run into problems read it again.

There are many ways to set up the CYRF This register controls some of the built in receive circuitry. The more obvious source of information is the Cypress website.

It does tell you what you need to get this chip to work but it is not always in the most obvious place on the datasheet or the most obvious register on the CYRF Without going into too much detail on how the radio in the CYRF works, chips have less immunity to noise and therefore shorter range but higher speed.

The guys at http: The first step is to set the CYRF registers for transmission. Cyrf datasheet, cyrf circuit, cyrf data sheet. Pins 11 and 12 on the module are outputs of the RF switch status so it is important not to set the logic of these pins.

Wirelessusb lp is the next generation wirelessusb device, with high data throughput and low power designed to operate in 2. While there are easier to use radio modules and transceivers out there i wanted to use the CYRF for it’s huge versatility and relatively low cost.

This function returns “0” if data has been successfully received. I wasted many weeks searching for the correct way to operate that modules RF switch.

Links to my other pages: One of the things i found intimidating when initially starting with these modules was getting an initial working config from which to start tweaking. If you are not an electronics hobbyist or know much about embedded electronics then be warned, this is going to be very dry reading for you. The CYRF can be used to add wireless radio communication to most modern microcontrollers. I am writing this page in the absence of any other resource for hobbyists to use this highly useful, high speed 2.

Downloads Sitemap Links to my other pages: My project uses Atmel AVR atmega microcontrollers for this.

There are a few hidden costs dattasheet using these modules. Set RX GO which causes the device to transition to receive mode. It is worth pointing out all 3 modules i have listed use the same 2×6 pin header. The transmitting module listens for this ACK and only reports a successful transmission if it is received.

Interfacing Cypress CYRF to AVR microcontrollers. – dunk’s stuff

Load transmit buffer with data. You will need to go to the Technical Reference Manual for the register descriptions. The Unigen datasheet does not mention this. The PA setting you will probably want to set to it’s fatasheet power. This is counter intuitive. The examples shown here presume Transaction Mode is switched off. This actually transmits the data and tests for successful transmission. Most users will want to leave this bit set. Returns “0” if TX was successful.


I suspect there is a misconfiguration in our clock setup and setting RXGO gets the clock running correctly.

Existing documentation on the CYRF This is a simple addition to the TX and RX code. It has no other RF switching or dataaheet circuitry to deal with so pins 10, 11 and 12 are unconnected. IBM laptops wireless cards and can be found on E-bay. Sb, 21mar11 3 this datasheet is subject to change without notice. The value here is the recommended from the Datasheet. Set your microcontroller to input if it is connected to these pins. Unfortunately all of the source code and configuration examples i could find for the CYRF are written in machine code for a Cypress microcontroller that i have no experience with.

The buffer is only 16 bytes long so the method described here will only darasheet up to that length. RXGO should only need set when receiving data.

Once you have things working you can experiment with other lower power options. But i love and use framebuffer when available, and it is can be very dafasheet even with very complex applications, on my desktop i have used vlc, xine, mplayer cyf6936 framebuffer. Either way, it works if you set it up this way. Tells the CYRF the length of the data being sent and fills the buffer.
