ECE 3567 Microcontroller Lab ECE 3567 Microcontroller Lab Lab #3 Pulse Width Modulation and the LED Test Mode Spring 2019 Dr. Gregg Chapman 1
ECE 3567 Microcontroller Lab ECE 3567 Microcontroller Lab This week, you are given MOST of the code for LED Test Mode. 2
Lab 3 Main() Lab 3 Main() 3
ECE 3567 Microcontroller Lab ECE 3567 Microcontroller Lab Download and install the project from the ECE 3567 Lab 3 website. 4
Lab 3 The LED Test Mode First of THREE Modes: 1. LED Test Mode 2. Temperature Measurement Mode 3. RC Voltage Feedback Mode 5
Lab 3 Compile and Program Lab Add the following Commands to parse_Command() LT Activate LED Test Mode LR = Red LED LO = Orange LY Yellow LG Green LB Blue LP Purple LD LED Test Mode Disable 6
Lab 3 Compile and Program Lab Add the following Pulse Width Definitions in update_RGB() NOTE: This is in RGB_LED.c if(LED_Test == TRUE) { if(LED_Color == Red) // Red. Includes Flash { duty_cycle_red = 0x070; duty_cycle_green = 0x000; duty_cycle_blue = 0x000; 7
Lab 3 Add the following Pulse Width Definitions in update_RGB() NOTE: This is in RGB_LED.c } else if(LED_Color == Orange) // Orange { duty_cycle_red = 0x0E4; //FF duty_cycle_green = 0x014; // 30 duty_cycle_blue = 0x000; } 8
Lab 3 Add the following Pulse Width Definitions in update_RGB() NOTE: This is in RGB_LED.c } else if(LED_Color == Yellow) // Yellow { duty_cycle_red = 0x0E4; //FF duty_cycle_green = 0x08B; // D7 duty_cycle_blue = 0x000; } 9
Lab 3 Add the following Pulse Width Definitions in update_RGB() NOTE: This is in RGB_LED.c else if(LED_Color == Green) // Green { duty_cycle_red = 0x000; duty_cycle_green = 0x04A; duty_cycle_blue = 0x000; } else if(LED_Color == Blue) // Blue { duty_cycle_red = 0x003; duty_cycle_green = 0x003; duty_cycle_blue = 0x07A; } 10
Lab 3 Add the following Pulse Width Definitions in update_RGB() NOTE: This is in RGB_LED.c else if(LED_Color == Green) // Green { duty_cycle_red = 0x000; duty_cycle_green = 0x04A; duty_cycle_blue = 0x000; } else if(LED_Color == Blue) // Blue { duty_cycle_red = 0x003; duty_cycle_green = 0x003; duty_cycle_blue = 0x07A; } 11
Lab 3 Checkpoints 1. Green LED illuminates when the UART is Connected 2. LT is written to the LCD when the command is sent 3. All 6 colors appear for the Color Commands in LT Mode. 4. LD disables the LED 5. LE Enables the LED 12
