#86520 - 4k7 is not good value Responding to: ???'s previous message |
hi,
It is not related to hang up problem, but may help you with another problem when AT89S52 does not open transistors time to time. I suggest you to increase resistors from 4k7 up to 6k8 or 10k or use ULN, second transistor, optocoupler etc. Read more there: http://www.8052.com/forum/read.phtml?id=74143 http://www.8052.com/forum/read.phtml?id=74217 Regards, Oleg |
