Why I ordered a raspberry PI

Why I ordered a raspberry PI

Things are complicatiatetered

But I need to jtag FPGA board from my laptop..
This FPGA JTAG cable is for a parport.
But raspberry PI has an IO header..
Also speed.. and via network, webpack is on yet on other PC here.

The second plan:
 being able to record IQ signals for almost any frequency band you can think of,
especially tried GPS, I was wondering if I could do an universal
replay attack by playing back the IQ via a quadrature modulator setup [1],
so dual DAC, QAM modulator, thinking about these 2 chips:
 AD9761  Dual 10-Bit TxDAC+ with 2 Interpolation Filters
 AD8349 700 MHz to 2700 MHz Quadrature Modulator

This will require a very precise replay at exactly the same 2048000 sample rate I recorded at.

But it will also create a DVB-T TV modulator as a side effect (with some software),
at the final frequency, so no up-conversion.
Anyways a replay of those secret NSA CIA transmissions, 
or providing the white house or wherever coordinates to local drones using GPS,
or retransmitting a full 1 MHz wide broadcast band ..

The other thing for the PI is to use it with the DVB-T stick as small portable 
spectrum analyzer, just port my software to ARM,
and add a LCD display...
Would make a GPS too, of software defined radio, or...

I wonder if I have to add some hardware FIFO (FPGA?) to make regular samples...

[1] will my noise (spread spectrum) when stronger then the normal signal noise,
that is below thermal, replace the whole constellation at once?

Anticipation.


;-)

seen the Pcduino? https://www.sparkfun.com/products/11712 it's a bit more expensive than the raspberry pi, but it's got 1GB ram, 2GB onboard flash and ADCs and I think you can actually get a datasheet for the CPU -Lasse

Wow! Nice! No heatsink needed, even, huh!

Get a Xilinx USB programmer clone from Ebay. They cost about $30 and work fine under Linux. -- Failure does not prove something is impossible, failure simply indicates you are not using the right tools... nico@nctdevpuntnl (punt=.) --------------------------------------------------------------

Do you know if the clones can read/write efuses? Documentation says not even the digilent programmer, which seems to be some what supported by xilinx can do it, only the real xilinx -Lasse

Interesting: http://www.pcduino.com/ have to make choices. The propriety data for the Broadcom chip does not bother me, Nvidia drivers on my other PC are not open source either, those work better than the nv x driver ... I also ordered a back plastic box, although I may place it in a metal box against RFI, and add a 128x64 LCD I still have around, the same one as in my gamma-spectrometer. I already downloaded the raspbian soft, put it on a 8GB SHDC card, and mounted it loop on the PC. had a look at what was there in the bin directory. Need to add my editor (joe), else I am lost :-) For kernel recompile maybe I should install arm gcc on a PC, will take hours on the thing itself, already I need kernel update before I even have it :-) Adventure :-)

Now I have an ethernet programmer :-) Laptop ssh -Y -> wireless -> LAN -> big fast multicore -> webpack Raspbery in ethernet port laptop. And it can do so much more than an USB programmer. It can replace many PIC projects, sure you like that :-) And why xilinx? jtag Altera, or that other one.. Actel. I just wanted JTAG, I used jtag for this one too: http://panteltje.com/panteltje/wap54g/index.html (actually that is also a Broadcom processor, but MIPS). parports are out these days, a while ago I bought a PCI parport card for a PC... But that PC is in an other location.. Carrying a PC from A to B every time is not very practical.

it start to add up when you need to add display etc. might as well get a cheap table like an Odys Xelio 99=80 from Conrad 7" display, capacitive touch, wifi, speaker, camera, battery, etc. comes with Android 4.0 but as far as I can tell the same cpu as the pcduiono so it should be possible to install linux -Lasse

Yes, I just looked that up at conrad.nl But is has no IO header ? Would make a nice spectrum analyzer if you could stick in the rtl_sdr DVB-T USB tuner. But I already have a HTC android (with real keyboard buttons) that I bought for control of a drone... (can then send pictjures of ground and be remote controlled over large distance (electric motor enhanced glider) via the cellphone towers). but there is some licensing problem here with airspace laws... But the android pissed me of, java in general actually, I just want Linux without some insulated layer of shit on it. Java makes everything 10 x slower, 100 x less secure, is C++ in nature, and that is in itself a crime against humanity, designed to destroy society by the clueless non-programmer Stroustrup http://www.stroustrup.com/ He is an information terrorist! Directly responsible for MS bloat! So, no android (stupid robot anyways) for me, but pure Linux, no C++ (like arduino for the same reason), just simple good ol'C. BTW I did see 3 ways to hack the Samsung ANDROID galaxy 4 today, in German: http://www.heise.de/newsticker/meldung/Sperrbildschirm-des-Samsung-Galaxy-S3-laesst-sich-umgehen-1818200.html How much worse can it get? Maybe I will buy an extra Samsung monitor soon... This one is not bad at all.... Especially after they repaired it once, and I replaced the caps in the power supply... Just some LCD burn in from xterms I guess. And .. I have 2 small PAL car monitors, that directly plug in the raspberry, color, good resolution actually, so small media player, or colored FFT display?? http://www.ebay.com/itm/170671900032?ru=http%3A%2F%2Fwww.ebay.com%2Fsch%2Fi.html%3F_sacat%3D0%26_from%3DR40%26_nkw%3D170671900032%26_rdc%3D1 (ebay item 170671900032 ) OK, :-)

It seems anyone can come up with an Arm SBCs these days. The deal is getting a supported linux distribution. I've been using linux on Arm for a few months. Ubuntu has it together. Opensuse is nearly as good. Fedora is way behind. But this is on community projects like Panda, Beagle and a few others. Once you leave the mainstream and have to start rolling your own distributions, this becomes way too much work. Ubuntu probably has the most money to throw at linux on Arm since it is part of their business model. Since Suse runs "build", they sort of have to be Arm literate. I guess Fedora wants to be able to support the Arm servers. [64bit arm probably] All these boards boot on SDHC (regular or micro), so it is easy to have a few distributions handy with your software installed. I've been getting 16Gbyte Samsung micro SDHC under $10 at Frys. That is about the size you need for a system if you are going to compile code on it. There are some cheap Samsung eval boards that in theory run linux.
