Recommendations on Logic Analyser for embedded debugging
(1/4) > >>
matth:
In past lives I have used some pretty sophisticated logic analysers to do debugging of complex digital systems (ie RISC CPUs, memory, PCI interfaces etc). 

Fast forward to today this is now a home hobby and mainly looking at vintage computers and arduino systems.  I am in need of a logic analyser for my home lab but as I will not use this very often I would like to seek advice on what my options are for cheap(ish) open source / ebay / Aliexpress options.

I do not need hundreds of channels and Ghz timing.  I am thinking I probably need enough channels to probe some address and data buses and a few enable signals.   Probably in up to 20Mhz but a bit higher would be a bonus.   What I need is something with decent software that I can record traces, decode some addresses and other protocols like I2C/SPI etc.

Suggestions ?

Start by looking at the BusPirate 5.

Looks cool for single wire protocols but not good for probing Address and Data buses - eg Z80, 68000 etc.
