Assignment

LCE_Hello .c controls multiple I/O ports, GPIOA & E being two of them. Study the program carefully. We will get into each of these I/O ports one by one for the rest of the semester. This homework is to enhance the understanding on how the program configures and controls GPIOE for the LED's and GPIOA for the pushbutton, and on how the program configures and controls I2C for the LCD panel display. Answer the questions below. L stands for the line number in the program. Type your answers and submit your work to BB Learner.

Hint:

a) Place LED_Hello.c inside STM32F3_Base project. Run uVision.

b) Following each question of the homework, right click on the relevant system defined functions and the variables, and find the answers. If necessary, multiple linking may be necessary.

c) It is acceptable to copy and paste the answers from the program.
