Write one paragraph of Critical Observation/thinking of what you saw and writing the code for the 8 LEDs on the Explorer 16 development board to generate a Knight Rider Pattern on those LEDs.
The Knight Rider pattern on the 8 LEDs of the Explorer 16 development board reminds me of the iconic red lights moving back and forth on the front of the Knight Industries Two Thousand (KITT) car from the TV show Knight Rider. It's interesting to see how a simple pattern can evoke a strong nostalgic response. As for the code, I would start by initializing the 8 LEDs as outputs and creating an array to store the sequence of on/off states. Then, I would use a loop to iterate through the array, toggling the corresponding LEDs on and off in a sweeping motion.
Add more
In addition to the basic implementation of the Knight Rider pattern, further enhancements could be explored. For instance, the speed of the LED movement could be adjusted to create different effects - a slower speed could evoke a sense of suspense, while a faster speed might create a more energetic mood. Another possibility is to add a fading effect, gradually decreasing the brightness of the LEDs as they move further away from the center. This would add an extra layer of visual interest to the pattern. Additionally, more advanced features such as synchronization with sound or user-controlled input could provide an interactive element to the pattern. These enhancements would require more complex code logic, possibly involving interrupts or timers, to achieve the desired effects.
There was two parts. Part a was to make the leds left to right and vice versa. Part B was if SW3 is pushed down and hold, the above pattern starts from LEFT to RIGHT and when SW3 is released, the pattern walks from RIGHT to LEFT.
Apologies for misunderstanding the requirements. Here is an updated code snippet that generates the Knight Rider pattern on the 8 LEDs on the Explorer 16 development board and incorporates the added functionality:
```c
#include <xc.h>
// Define LED ports
#define LED_PORT LATB
// Define button port and pin
#define BUTTON_PORT PORTB
#define BUTTON_PIN RB5
// Define delay time
#define DELAY_TIME 200
// Function to initialize LED ports
void initLEDs() {
TRISB = 0x00; // Set all pins of PORTB as output
LED_PORT = 0xFF; // Turn off all LEDs initially
}
// Function to create Knight Rider pattern
void knightRiderPattern() {
unsigned char pattern = 0x81; // Starting pattern (leftmost and rightmost LEDs on)
unsigned char direction = 1; // Direction of pattern (1 for left to right, -1 for right to left)
while(1) {
// Check if SW3 is pressed
if(BUTTON_PORT & (1 << BUTTON_PIN)) {
direction = 1; // Set direction to left to right
}
else {
direction = -1; // Set direction to right to left
}
// Update LED pattern
if(direction > 0) {
if(pattern == 0x01) {
direction = -1; // Reverse direction when reaching rightmost LED
}
else {
pattern = pattern << 1; // Shift pattern one bit to the left
}
}
else {
if(pattern == 0x80) {
direction = 1; // Reverse direction when reaching leftmost LED
}
else {
pattern = pattern >> 1; // Shift pattern one bit to the right
}
}
// Output pattern to LEDs
LED_PORT = pattern;
// Delay
__delay_ms(DELAY_TIME);
}
}
int main(void) {
initLEDs(); // Initialize LED ports
knightRiderPattern(); // Generate Knight Rider pattern
return 0;
}
```
In this code, the Explorer 16 development board's PORTB is used as the LED port, with RB5 serving as the button input for SW3. The knightRiderPattern() function continuously updates the LED pattern based on the button state, shifting the pattern left or right depending on the direction of movement. The LED pattern is then output to the LED ports (PORTB) and a delay is implemented to control the speed of the pattern's movement.
