Saleae16 Logic16 100M 16 Channel Logic Analyzer
Filed under: Development, Hardware, Linux, Robots, Ubuntu
I got a clone of the Saleae16 Logic16 100M 16 Channel Logic Analyzer a few days ago to test some of the arduino stuff I’ve been working on for the last few months.
I was at first really annoyed because the software simply refused to work, I tried it on 4 different computers, ubuntu 13.10 64bit, Windows 7 32bit and 64 bit and same error for all of them, logic too slow for speed, try reducing blah something. My searches came up with very little info.
So in the end I found the sigrok package and compiled myself (old version in Ubuntu lacked saleae support) and was pleasantly surprised! It works and actually seemed to be an OK package! There are a few things to do before that which wasn’t obvious, you need to extract firmware from the Saleae software suite and so on for example. Also there are a few bugs in the graphical interface that I found so far. I’ll try to get them reported ASAP and possibly do some work on them. I’ll get back to this topic a bit later as it wasn’t completely obvious how to get it running at all points, for now however, it works;).
Arduino nano computer controlled Pulse generator
Most projects as of late are kind of stopped indefinitely due to lack of time (who could have thought 2 kids could take so much time…) . I am working on 2-3 things whenever I do get a few minutes in and I feel like it however.
The most interesting I believe is a arduino nano based pulse generator, due to a lack of built in DAC it will only be digital. It will be reconfigurable via a qt library which in turn is driven by a qt gui at the moment, but it should be possible to control via any other application. It currently supports 7 pin modes:
digital in
Digital out
built in pwm
bitbanged pwm
handled interrupts
forwarded interrupts and
analog in.
