(I agree) I guess the important bit for his post relates to the fact that the removed bits no longer need the GPIO pins to drive them any more so could be used for other things. That said. I agree with the other point that protection like this doesn't sound like something that should be 'hard enforc...

I am guessing the Model A?

Hi Soren,

(This thread is a bit old so sorry if no longer applies...)

I am working on the same thing - connecting an RFM12B to the pi.

Details at http://jeelabs.net/boards/6/topics/213 if it is still of any interest.

Thanks

Stephen

Hi Peter,

If you want to connect using FSK rather than OOK you might want to take a look at the JeeLabs forum at http://jeelabs.net/boards/6/topics/213.

Thanks

Stephen

Hi,

I got some way with interfacing an RFM22B to the pi over the last couple of days if useful.

Hi Arjan, The C library worked an abosluete treat. Data coming in perfectly now with no overflows that I can see. Thanks very much indeed. (And thank you very much Mike, too). Will keep a close eye on the progess of the SPI Kernel driver and try that again when the patch is put in. Thanks again Step...

Thanks very much Gordon. Unfortunately I need to do a number of 2 byte transfers in quick succession (to prevent a small FIFO from overflowing) so the latency issue is a bit of a killer. I see from one of the other threads that there are potential speed improvements in the normal driver so I am sure...

Thanks very much indeed Arjan.

I will take a look at all of those!

Thanks

Stephen

Hi, I am very new to SPI so I appologise in advance if this is a silly question... I have been trying out some code to conect an SPI module to the pi. I seem to be able to get data to go back and forth ok but the data throughput seems very low. I see that the initialisation routine of the SPI bus (i...

Hi Peter, I am not sure if this is related. I was running some code yesterday using SPI (via WiringPi). Happened to be running it over SSH so I was able to cut and paste the error. It ran fine for a while but then I got : Message from [email protected] at Dec 30 17:20:58 ... kernel:[87218.103894] ...

Just to add to the stats.

I have the same problem. Also have a Kingston class 4 SD card. (8GB)

Hi, In case anyone with problems getting their devices to be recognised has the same problem I had: Don't forget that there are two numbering schemes for the GPIO pins! You need to connect it to the pin 3 up from the 3.3V output (otherwise known as GPIO 7) *not* the one 7 up from the 5v pin (which i...
