#82132 - EMI/RFI noise |
Hallo
Maybe I'm not asking on the right forum,so, please excuse me. I'm using a 8052 based controller to command some electrical engines and electrovalves (max. 1A). Not always, but some times, when the power components starts, the whole system goes crazy. This means uncontrolled jumps to other routines than the correct ones.And this is the happy case of EPROM stored program. With RAM simulated EPROM, the situation is much worse: the program became corrupted imediatly. I know, this is a EMI/RFI problem, but i have no experience in this domain. Please, some ideas or some links would be very usefull. Thank you. |
