Cheap handheld serial analyzer?

[rea5245]

There are lots of times I'm working on a project and I need to watch UART, SPI, or I2C traffic (or maybe even generate it). Instead of plugging a USB device into my PC and running software, I'd love to have a handheld device with an LCD and test leads that can do the job. It seems that a cheap, hobby-grade device would be easy to make, and yet I can't find such a thing for sale.

Is anyone aware of a device like this?

Thanks,

There's probably a way to use an Arduino to do this...

yes a nice tactile user interface on top of a bus pirate would do it... who starts it ?

What's needed is a port of LogicSniffer to android.

I could hear the *GROAN* from here. XD

Other than that, use this and then port this to android.

Well you of course. Who else? I already have it working nicely on a laptop on the bench, so no real motivation to port ols to android. Opensauce tradition dictates that if you want something bad enough, you just implement it yourself.
