Mac's are excellent tools for accessing serial device TTY ports (to console into PBX's, switches, and routers). You just need a serial to USB adapter, the right driver, and some Terminal software. You can use screen, although ZTerm, goSerial, or Mini…

The BGND interface provides the standard 6 pin connection for the single wire BGND signal type development port.   Target types that apply this development port are the 9S08, RS08, and Coldfire V1.   +V_TRG, TBGND, TRG_RST*, and Ground are applied by…

原文出自 http://hilbert-space.de/?p=135 While laying out a PCB for my SWP reader project I realized that I haven’t ever tested the ISO-7816 (aka contact) interface yet. I probably forgot that because it’s not all that difficult and not that interesting,…
