#26152 - Operating 2nd 8051 from 1st8051 port pin |
Hi,
I want to supply +5v power supply to second 8051 micon with 8051. and i want to supply power for 2seconds and stop supply for the next 2seconds ,like that alternately..i did it thru program(setb,clr.) When i've connected p1.0 of 1st micon to power up second 8051, iam only getting 0.3v maximum,but when i disconnect it iam getting +5v at p1.0.. Then i've tried connecting a transistor but could'nt. How can i get power to 2nd micon from port pin of the 1st micon so that,it should run as a usual micon runs. Please suggest me.. regards, rams |
