Some hints :
* Stop using WIN-ISP. Use FlashMagic instead. * You will need a reset controller or supervisor IC for the Flash MCU to do your bidding. RC resets are useless here. ( DS1232, DS1834, MAX700 to 708 are some such ICs) Initially choose a model that does not have a watchdog. Simpler that way. * Download and read the latest AN461 application note from Philips website to understand more on this ISP stuff. * Search this forum for "ISP" and also visit the www.esacademy.com site for more tips and tricks to use FlashMagic. The above should help you in getting going with the ISP MCU. And I am not sure what schematic you want. All required is in AN461. Check it out. Raghu |
