To configure a port as input or output DDRx instruction is used. If the particular pin has value 0 then it is configured as input, if 1 is set then it is configured as output. For first 5 pins to be set as output we need 11111 value, for 5-7 pins as input we need 000. First bit starts from right and last bit ends towards the left.
DDRD =0b00011111;
Converting to hex,
DDRD = 0x1F; //serves required purpose
To enable pull-up resistance on input pins use PORTx instruction. If a PIN is set to 1 in PORT instruction, the enable resistance is enabled. If it has a value 0 then the pull-up resistance is disabled. If disabled, the PINs go in tri-state where their value cant be determined which can lead to problems in circuit further. To enable PIN 5 and 6, set them to 1 in PORTx.
PORTD = 0b01100000;
PORTD = 0x60;
These instructions serve the purpose,
DDRD = 0x1F;
PORTD = 0x60;

Question 3: In class we showed how to simply light up an LED on our Teensy microcontroller. In fact, the procedure is similar for all processors including a simpler 8-bit ATmega 328P (a.k.a Arduino Uno) For purposes of this exercise, let's say that the ATmega328 has 4 regular GPIO ports; A, B, C, and D, each with 8 pins. Every GPIO port has three registers (outlined in table below) PORTX: used to write output on a pin on port X...

Lab 3 - Branching, Push Button and LEDs-Reading Assignment in this lab, we are going to control a LED via a push button- using general purpose digital 10 for both input (button) and output (LED) on port 1 - using Code Composer Studio. Furthermore, we are going to use a branch instruction to create an IF-ELSE structure in assembly to determine if the LED should be lit up based on...
