Or do a video youtube? The speed is very slow about 1k2 baud. Unfortunatly i am not familiar with Arduino, Rasberry or Beagleboard. Also, they may suffer from thermal issues during long transmissions. CRC of the whole frame big-endian.

Also, they may suffer from thermal issues during long transmissions. Chipcon on Raspberry Pi Mon Oct 21, 1: Hi guys, are there any people have tried to install CC RF module on raspi?

Initially, I wanted to make my code a regular user-space program. CRC of the whole frame big-endian. This allows me to access Hamnet from my laptop. Unfortunatly i am not familiar with Arduino, Rasberry or Beagleboard. Length of the whole frame.
Finish cc transceiver spi driver for BeagleBone black PCB | Linux
Chipcon on Raspberry Pi. They are intended for real-time applications and can be programmed using an assembler code that runs at one instruction per clock cycle. 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.
I guess its reliable currently. My contact info is at the bottom of this site. Board index All times are UTC.
Your email address will not be published. Big-endian 16bit unsigned integer. I am probably missing something obvious but I searched spidev here and see other have had similar issues.
Using the CC1101 and Beaglebone black for IP traffic on 70cm
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. The goal of my project is to build an affordable 70cm IP transceiver with a power of a few Watts. Would you specify your project in more detail? So I suspect I will swap it out for a different module.
I am testing the stability of my code by running two of these CC modules at home, each on its own Beaglebone black. Also nice thing about that your used parts are tiny and cheap.
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. Although the usual maximum bandwidth in the 70cm band is 20kHz, the IARU R1 bandplan allows for wideband experiments around 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.
Sometimes though, it simply stops receiving and I want the ability to perform the proper boot sequence to reinit the chip.
There is a generic “spidev” driver on my raspi so do I have to install another specific driver for CC? One of them is connected to my Hamnet network, using a bridge between the TAP interface and the ethernet interface. 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.
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. Presumably, this will suffer from linu when using the higher data rates supported by the CC, as his software is not real-time.
