hello.. i am a newbie and using 8051 Micro controller. i have a problem and hoping that some of you guys can help me... i am getting a data strings of '1' and '0' from a radio receiver. I am trying to control a movement of 2 motors with the data that is received. i am using the edge triggered external interrupt to determine the start of the data bits. as an example.. i will receive a string of 10111. the first two bits will trigger the edge trigger interrupt and the last three bits will be the data bit and means that the motor moves forward. how is it possible to read the data bits and send it to the motor to move forward? i have done the external interrupt using C. I just can't figure out on how to read the data... the cycle time is 10ms. because the external interrupts happen at P3.3 is it ok if the data comes in through there to?
