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. 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. Hi guys, are there any people have tried to install CC RF module on raspi? I guess its reliable currently.. Length of the whole frame. It should be fine with the default clock speed, mode0 etc but writing the register data and reading it back is returning 0x2f.. Chipcon on Raspberry Pi Fri Oct 18,

One of them is connected to my Hamnet network, using a bridge between the TAP interface and the ethernet interface. Although the usual maximum bandwidth in the 70cm band is 20kHz, the IARU R1 bandplan allows for wideband experiments around Board index All times are UTC.
Chipcon on Raspberry Pi – Raspberry Pi Forums
Chipcon on Raspberry Pi Sat Jan 18, 4: Also nice thing about that your used parts are tiny and cheap. They are intended for real-time applications and can be programmed using an assembler code that runs at one instruction per clock cycle. 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 Xc1101 by itself goes only up to 10dBm.
Chipcon on Raspberry Pi. Its not particularly gcc friendly with having to create a makefile of manually link the library at compile time either.
I guess its reliable currently. CRC of the whole frame big-endian. 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.
The problem is linus a Linux user-space program can be forbidden to run for several milliseconds while the kernel is busy serving interrupts.
Chipcon on Raspberry Pi Fri Oct 18, 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. 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.
Sometimes though, it simply stops receiving and I want the ability to perform the proper boot sequence to reinit the chip.
Using the CC1101 and Beaglebone black for IP traffic on 70cm
So I suspect I will linnux it out for a different module. Presumably, this will suffer from problems when using the higher data rates supported by the CC, as his software is not real-time.
Length of the whole frame. It should be fine with the default clock speed, mode0 etc but writing the register data and reading it back is returning 0x2f. I am testing the stability of my code by running two of these CC modules at home, each on its own Beaglebone black. By maintaining a simple packet format, this system can be interfaced with others, as the CC supports a wide range of digital modulations and rates.
Using the CC and Beaglebone black for IP traffic on 70cm – Daniel Estévez
This allows me to access Hamnet from my laptop. Hi guys, are there any people have tried to install CC RF module on raspi?
Thanks and greetings from Germany Patric. Further on-the-air tests will perhaps change these parameters a bit. Unfortunatly i am not familiar with Arduino, Rasberry or Beagleboard. Chipcon on Raspberry Pi Mon Oct 21, 1: So far, it seems to work well.
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.
Finish cc1101 transceiver spi driver for BeagleBone black PCB
The goal of my project is to build an affordable 70cm IP transceiver with a power of a few Watts. Learn how your comment data is processed. There is a generic “spidev” driver on my raspi so do I have dc1101 install another specific driver for CC? A data rate of kbps with MSK modulation seems about right, as it uses roughly kHz of spectrum.
