The Unified Pin Control system is an Arduino sketch designed to simplify GPIO pin control through serial communication. This system supports configuring and controlling GPIO pins with various commands. You can set pin modes, write values, read inputs, and deactivate pins, all while receiving real-time updates.
- Configure pin modes:
INPUT,OUTPUT,INPUT_PULLDOWN - Write digital values:
HIGH,LOW - Write PWM values with automatic range constraints
- Read digital and analog values
- Deactivate pins and reset all pin configurations
- Real-time status updates at predefined intervals
Description: Configures the selected pin as an input pin for digital reads.
Usage:
GPIO(pin number) INPUT
Example:
GPIO4 INPUT
Expected Output:
PIN MODE TYPE VALUE
GPIO4 INPUT DIGITAL LOW
Description: Configures the selected pin as an input pin with an internal pull-down resistor.
Usage:
GPIO(pin number) INPUT_PULLDOWN
Example:
GPIO2 INPUT_PULLDOWN
Expected Output:
PIN MODE TYPE VALUE
GPIO2 INPUT LOGIC LOW
Description: Configures the selected pin as an input pin for analog reads.
Usage:
GPIO(pin number) ANALOG
Example:
GPIO12 ANALOG
Expected Output:
PIN MODE TYPE VALUE
GPIO12 INPUT ANALOG 512
Description: Configures the selected pin as an output and sets it to HIGH.
Usage:
GPIO(pin number) HIGH
Example:
GPIO14 HIGH
Expected Output:
PIN MODE TYPE VALUE
GPIO14 OUTPUT DIGITAL HIGH
Description: Configures the selected pin as an output and sets it to LOW.
Usage:
GPIO(pin number) LOW
Example:
GPIO15 LOW
Expected Output:
PIN MODE TYPE VALUE
GPIO15 OUTPUT DIGITAL LOW
Description: Configures the selected pin as an output and sets its PWM value. The value must be within the range of 0 to 255 (default 8-bit resolution).
Usage:
GPIO(pin number) (integer)
Example:
GPIO12 128
Expected Output:
PIN MODE TYPE VALUE
GPIO12 OUTPUT PWM 128
Description: Deactivates the selected pin.
Usage:
GPIO(pin number) REMOVE
GPIO22 REMOVE
Description: Deactivates all configured pins.
Usage:
REMOVE ALLDescription: Displays the help message with a summary of available commands.
Usage:
h
H
HELP
Example:
HELP
Expected Output:
Unified Pin Control
Available commands:
1. GPIO(pin) INPUT for digitalRead
2. GPIO(pin) ANALOG for analogRead
3. GPIO(pin) INPUT_PULLDOWN for digitalRead with pull-down resistor
4. GPIO(pin) HIGH or LOW for digitalWrite
5. GPIO(pin) (integer) for analogWrite
6. GPIO(pin) REMOVE to deactivate pin
7. REMOVE ALL to deactivate all pins
8. h, H, or HELP for command help
The system displays the status of each pin, including:
- PIN: The GPIO pin number.
- MODE: The pin's mode (e.g., INPUT, OUTPUT).
- TYPE: The type of value read or written (e.g., DIGITAL, ANALOG, PWM).
- VALUE: The current value of the pin.
- Upload the sketch to your Arduino board using the Arduino IDE.
- Open the Serial Monitor at a baud rate of 115200.
- Enter commands as described above to configure and manage the GPIO pins.
