Hello Guillermo, Joe etc, >>Can anyone recommend a decent PC-based logic analyzer >>with USB connection? So far I've found a couple of nice >>ones but all of them were parallel port only... >As a matter of interest, which parallel port ones have you been looking at ? >I'm looking at getting one for home use (or building one) and parallel isn't a problem for me. have you heard about BitScope (www.bitscope.com)? It's a dual-channel sampling osciloscope with 8 logic inputs. It's not very expensive as you can buy the complete assembled kit for US$395.00. Also, you can learn a lot studing the squematics and the PIC software. Surelly, there'll be some tricks you'll love and incorporate it on your projects. The hardware is very good but there's not a "really pro" software for it yet. The better one is the Scopal (www.scopal.com). However, the guys at BitScope are working on some enhancements and the new "official" software is comming soon. The demo version on the website is very impressive. You connect it to PC via RS232, not USB, but they're working on a Network Interface Adaptor!
