So far, it seems to work well. Its not particularly gcc friendly with having to create a makefile of manually link the library at compile time either. Initially, I wanted to make my code a regular user-space program. Learn how your comment data is processed.

I am probably missing something obvious but I cc1101 spidev here and see other have had similar issues. Chipcon on Raspberry Pi. One has to be a bit careful with these amplifiers, as they lack filtering after the amplifier and will probably need a low-pass filter to comply with the regulations.

Thanks and greetings from Germany Patric. Would you specify your project in more detail?

The problem is that a Linux user-space program can be forbidden to run for several milliseconds while the kernel is busy serving interrupts. A data rate of kbps with MSK modulation seems about right, as it uses roughly kHz of spectrum. Hi guys, are there any people have tried to install CC RF module on raspi?

Chipcon on Raspberry Pi – Raspberry Pi Forums

The goal of my project is to build an affordable 70cm IP transceiver with a power of a few Watts. This hides away all the complexity in the PRU code and makes it possibly to implement easily different FEC codes and checksums in the user-space code.

One of them is llinux to my Hamnet network, using a bridge between the TAP interface and the ethernet interface.

Chipcon on Raspberry Pi Fri Oct 18, Chipcon on Raspberry Pi Mon Oct 21, 1: I am testing the stability of my code by running two of these CC modules at home, c1c101 on its own Beaglebone black. Also, they may suffer from thermal issues during long transmissions. Big-endian 16bit unsigned integer.

Using the CC1101 and Beaglebone black for IP traffic on 70cm

However, nothing stops one of using a really complex FEC, beacause the Beaglebone has enough CPU power to handle this at the relatively low data rates used. Chipcon on Raspberry Pi Sun Jan 19, 1: It is quite inexpensive and popular, and there are several modules in the market that include the CC and an RF amplifier in a small board the CC by itself goes only up to 10dBm. Although the usual maximum bandwidth in the 70cm band is 20kHz, the IARU R1 bandplan allows for wideband experiments around Length of the whole frame.

Sometimes though, it simply stops receiving and I want the ability llinux perform the proper boot sequence to reinit the chip. Unfortunatly i am not familiar with Arduino, Rasberry or Beagleboard. Installed wiringPi as it seemed suitable but am yet to find a way to ‘release’ the GPIO back to the spi module using wiringpi, spidev needs a reboot before the spi works correctly again.

This allows me to access Hamnet from my laptop. Also nice thing about that your used parts are tiny and cheap. It should be fine with the default clock speed, mode0 etc but writing the register data and reading it back is returning 0x2f.

So I suspect I will swap it out for a different module.
