Day 03 and Day 04(Week 1)

• Level Converter:
  To interface TIVA board with Firebird V, we need level converters as the Firebird operates at 5v and TIVA board operates at 3.3v. We came up with two circuits to achieve the above functionality. The first one uses a diode in reverse bias condition to convert 5v to 3.3v. The second one uses BJT in cut off and active region to bring about the same functionality.

• Lab 0:
  In this lab, we learned the output interfacing in tm4c123gh6pm and the basics of creating a project in Code Composer Studio. The tm4c123gh6pm has 3 inbuilt RGB LEDs connected to pin 1, pin 2 and pin 3 of the port F respectively. The aim of this lab was to switch on these LEDs in a sequence.

• Lab 1: In this lab, we interfaced switches present in tm4c123gh6pm. tm4c123gh6pm has two inbuilt switches connected to pin 0 and pin 4 of port F. The aim of this lab was to switch on the LEDs based on the state of the switches.

Problems Faced:
Pin 0 of port F is a special purpose pin, hence it is locked. The switch 2 is connected to this pin. So the pin has to be unlocked before setting it as an input pin.
