Instruments

This plugin contains the following instruments:

Actuators

• Servo: Control of an SG90 servo motor using PWM signals with the gpiozero and pigpio libraries. The servo can be positioned within a range of 0° to 180°.

Viewer0D

• RPitemperature: Raspberry Pi CPU Temperature Sensor. Monitors and displays the Raspberry Pi CPU temperature in real-time. The temperature is updated based on a configurable sampling time or frequency.
• DistanceSensor: Distance Sensor (HC-SR04). Measures distance using the HC-SR04 ultrasonic sensor, with adjustable trigger and echo pins, and configurable sampling interval.

PID Models

This plugin currently does not include any PID models.

Extensions

Installation Instructions

• PyMoDAQ Version: >= 4.0
• Tested On: Raspberry Pi 4 B+
• Required Libraries: - gpiozero: Python library for controlling the GPIO pins. - pigpio: Library for controlling GPIO pins via PWM, necessary for controlling the servo motor.

Steps to Install

1. Clone the Repository: Clone the repository to your Raspberry Pi.

   git clone https://github.com/sosasol/pymodaq_plugins_raspberrypi.git

2. Install the plugin: Run the following code.

   cd pymodaq_plugins_raspberrypi
   pip install .

3. Activate pigpiod: You will have an error when using the plugin unless you activate pigpiod with the following code:

   sudo pigpiod
