Lab

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.

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.
