Dear all, i am using P89V51RD2 (philips) 8051 micro-controller. i am doing some samples with NSK developemnt kit. In this i want to set the Port1 pint 0 to 7 as high/low continiously. I tried this by using the following lines,
P1 = 0x00 ; delay(10000) ; P1 = 0xFF ;
but still i am always getting around 5V on these pins. i searched lot of forums, but in that also they mentioned like this only. Kindly give your suggessions.......
Thanks and Regards Radhakrishnan M
You might also see smoke, since the processor pin will try to short whatever is connected to ground.
