c program language Homework

Lab #3 

The main program configures initializes IO peripheral blocks, then  puts itself in an infinite loop.

a)     The program blinks all LED's at every 1 second on and 1 second off.

b)     When the push button is pressed, the LCD panel displays "Red Alert!" for 3 second then clears.

c)     The top of the program should have a comment block as shown below.

/*      EECE 237 S15 Lab3

*Student Name:

*Student ID:

*Class section number:

*/

d)     The main() is written as follows. Do not change this.

int main(void) {

IO_init();

while(1);

}

e)     Use SysTick_Handler() in order to blink LED's.

f)      Use EXTI_IRQHandler() in order to detect the push button and to display a message on the LCD panel. Use the conventional time delay program to check 3 seconds because SysTick is occupied for LED operation.

g)     IO_init() contains all lines to enable and configure GPIOE, GPIOA, SysTick, SYSCFG, NVIC, EXTI, I2C2  and LCD Panel.

h)     IO_init() should not contain any lines that operate LED's or LCD panel.

i)      Use LCD_Hello.c and previous lecture notes for reference.

j)      Place line comments in as many lines as possible for easier reading.

k)     Submit your work to BB by 5/8/2016 Midnight.
