SX48BD Chip and Javelin Stamp

Ryan Hollister

I recently purchased a Professional Dev Board and also the Javelin Stamp. The ultimate goal was to be able to read in these very high frequency pulses, recognize a pattern in them, and output a pulse at a certain point in the pattern. There is 1030 cycles of this pattern every second with a pattern consisting of 13 pulses at random points in that pattern. After working on this project for a while, I came to the conclusion that the javelin stamp just wasn't fast enough for it was missing pulses while executing the other code, and if even one pulse is missed during this time, the whole pattern is useless. So after doing some more reading I stumbled upon your SX48BD chips and all the other SX chips you have. My question is, is it possible to access the Ubicom chip that is on the javelin stamp directly? The reason for doing this is i am sure the Ubicom chip would suffice in speed and with the ability to write assembly code directly to the chip it would make it much faster than having to go through the interpreter. I know I can go and buy all the other parts to program a SX chip directly on the dev board. But I have 100 bucks+ already invested in this javelin·stamp and I cant see trashing it when the Ubicom chip is sitting right there. I appreciate any help.

You can't reprogram the SX48BD of the Javelin module. And even if you could,

that would require an sx-key and the Java Virtual Machine inside it would be lost.

I am sure the SX48 and SX52 can process your pattern. The best approach is

to get an sx-key and a SX52 protoboard and programming that as a co-processor

for your Javelin, so you can do all the string input/output on the Javelin, while

the SX52 handles the patterns.
