II. Problem
Problem Description
Detail description of the problem goes here.
Your problem must have at least 3 modes(states). Explain necessary states(modes) and description
Example diagram:
Description of system modes, how your MCU should function and more
For example:
1. System Mode:
MODE | Description |
Normal Mode (NORM_MODE) | Pressing MODE_button (B1 of MCU_1) toggles from NORM_mode 🡨🡪SECUR _mode |
Security Mode (SECUR_MODE): | Pressing STOP_button (B1 of MCU_2) resets from SIREN_mode to SECUR_mode. |
2. Front Door:
MODE | Description |
Normal Mode (NORM_MODE) | When a person is detected within the given distance from the door(outside): Keep turning on the door light as long as the person is present. When a person is detected inside the house nearby the door: Turn on the door light for given period of time and does not generates the SIREN _TRG trigger. |
Security Mode (SECUR_MODE): | When a person is detected within the given distance from the door(outside): Keep turning on the door light as long as the person is present and sends the VISITOR_LOG message to the server. When a person is detected inside the house nearby the door: Keep turning on the door light and generates the SIREN _TRG trigger. |
3. Sensor Unit: MCU_1
Function | Sensor | Configuration | Comments |
Door Person detect (front) | Ultrasonic distance sensor | Sampling 0.1 sec Check object presence within 30cm Generates PERSON_OUTSIDE flag | Need to check for outlier measurements (at least 7/10 Postive) VISITOR_LOG under SECUR_MODE |
Door Person detect (inside) | PIR motion sensor | Edge trigger Generates PERSON_INSIDE flag |
MCU Configuration
You are free to select appropriate configurations for the design problem. Create a configuration table to list all the necessary setup.
Example:
Functions | Register | PORT_PIN | Configuration |
System Clock | RCC | - | PLL 84MHz |
delay_ms | SysTick | - | |
Bluetooth | USART1 | TXD: PA9 RXD: PA10 | No Parity, 8-bit Data, 1-bit Stop bit 9600 baud-rate |
Timer Interrupt | TIMER1 | ... | ... |
