4x4 keypad can be connected using two ports only, one for input and the other for output True False *To display y=27 on the LCD display, it must use printf () with %u %d None of the above % O % O A LM35D temperature sensor with sensitivity of (1C/10mv) is connected to ADC (Analog to Digital Converter) in PIC16F877A ADC operates with 10 bits, 5v reference voltage. If the PIC reads a digital 60, the real ... temperature that is measured is 45 CO 29 C 37 C O 41 CO 23 CO To set only the last 3-bits of the port B as an input, it must write the instruction set_tris_b(OXEE) O set_tris_b(OXEO) O set_tris_b(0x07) O set_tris_b(0x0E) set tris b(0x70)
