It should be fine with the default clock speed, mode0 etc but writing ccc1101 register data and reading it back is returning 0x2f. However, I found out soon that the 64byte buffer of the CC empties quite fast in 4ms at kbpsso the code should run often enough to refill the buffer.
Using the CC1101 and Beaglebone black for IP traffic on 70cm

Chipcon on Raspberry Pi Sun Jan 19, 1: Chipcon on Raspberry Pi Mon Oct 21, 1: This hides away all the complexity in the Cc1110 code and cc101 it possibly to implement easily different FEC codes and checksums in the user-space code.
Although the usual maximum bandwidth in the 70cm band is 20kHz, the IARU R1 bandplan allows for wideband experiments around 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. Would you specify your project in more detail?
Further on-the-air tests will perhaps change these parameters a bit.
Presumably, this will suffer from problems when using the higher data rates supported by the CC, as his software is not real-time. Learn how linxu comment data is processed.
Its not particularly gcc friendly with having to create a makefile of manually link the library at compile time either. 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. One of them is connected to my Hamnet network, using a bridge between the TAP interface and the ethernet interface.
This allows lnux to access Hamnet from my laptop. The problem is that a Linux user-space program can be forbidden to run for several milliseconds while the kernel is busy serving interrupts. Chipcon on Raspberry Pi. Initially, I wanted limux make my code a regular user-space program. The speed is very slow c1101 1k2 baud.

I guess its reliable currently. 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.

Board index All times are UTC. Sometimes though, it simply stops receiving ,inux I want the ability to perform the proper boot sequence to reinit the chip.
However, nothing stops one of using a really complex FEC, beacause the Beaglebone has enough CPU power ,inux handle this at the relatively low data rates used. Or do a video youtube?
I am probably missing something obvious but I searched spidev here and see other have had similar issues. Unfortunatly i am not familiar with Arduino, Rasberry or Beagleboard. A data rate of kbps with MSK modulation seems about right, as it uses roughly kHz of spectrum. They are intended for real-time applications and can be programmed using an assembler code that runs at one instruction per clock cycle.

Hi guys, are there any people have tried to install CC RF module on raspi? Chipcon on Raspberry Pi Fri Oct 18, The goal of my project is to build an affordable 70cm IP transceiver with a power of a few Watts.
