Hi When I single step my software in MPLAB on the PICMaster, the stack window doesn't seem to work with the program, but rather with some to-be-invented piece of software. It doesn't show calls, the suddenly it shows an overflow (after a single embedded assembly step), or underflow, depending on how it feels at the moment. Is there anyone with a suggestion or two? -- Friendly Regards Tjaart van der Walt mailto:tjaart@wasp.co.za ________________________________________________________ | WASP International http://wasp.co.za | | R&D Engineer : GSM peripheral services development | |Vehicle tracking | Telemetry systems | GSM data transfer| |Voice : +27-(0)11-622-8686 | Fax : +27-(0)11-622-8973 | | WGS-84 : 26010.52'S 28006.19'E | |________________________________________________________|
