What you have provided is totally inadequate! Nandhu Kumar said:
When i swtich on other appliance like fan or light the lcd displays show some $$ and ??? What sort of fan? What sort of light? What does "like" mean - have you tried other appliances? Are they some appliances that don't cause this effect? Are these appliances controlled by your 8051? Do they share a DC power supply? Are they on the same AC mains outlet? Or in the same room? Or on the same phase? What steps have you taken to examine this behaviour yourself? Does your 8051 have a proper reset generator & power monitor? Have you searched this forum for "brownout?" Have you looked in the FAQs for Techniques to improve EMC? etc, etc, etc,... |
