The configuration in which each LED receives operating current of 8 mA from power supply while the port lines sink the current on each port line is
|
|
common port configuration
|
|
|
common anode configuration
|
|
|
common cathode configuration
|
|
|
none of the mentioned
|
Explanation:
Detailed explanation-1: -Explanation: The common anode configuration is preferred to that of other configurations as in common anode configuration, each LED receives operating current of 8 mA from power supply while the port lines sink the current on each port line.
Detailed explanation-2: -Weare using Port P0 of 8051 for connecting the stepper motor. HereULN2003 is used. This is basically a high voltage, high current Darlington transistor array.
Detailed explanation-3: -Port C contains the lower 8 bits of the address bus (A0 – A7) and also functions as the data bus (AD0 – AD7) because it is time-multiplexed.
