Dear PICers, Being on the trail more than at the workbench, I bought the Proteus Lite simulator (www.labcenter.co.uk) to be able to develop & test PIC software on the go. This simulator runs a .hex file in a simulated PIC with on-screen animations and instrumentation in the schematic diagram. You have to see it to believe it! The samples like a PIC calculator and PIC clock run fine, but I cannot get a simple '874 program to run (nothing fancy, just turn on a LED on B1. Has any of you experience with this simulator? Are there any tricks I need to be aware of? Proteus support is on leave until early Jan 2002, sigh...
