Brushless 17 Click Demo (Red Pitaya)

This README explains how to run the Brushless 17 Click demo every 30 seconds on your Red Pitaya, along with what was done to complete the project.

---

✅ What Has Been Done

• ✅ Added brushless_17.py to the Examples/python/ folder

  • On the latest Red Pitaya OS 2.00, the following approaches did not work:
    • Modifying system GPIO files manually
    • Using the C API (which also touches those GPIOs)
    • Python macros provided by Red Pitaya
  • ✅ Only direct register access using the Python API worked successfully

• ✅ Added dc_motor.py and gpio.py as test scripts in the same folder

• ✅ Added systemd unit files for portability:

  • brushless.service
  • brushless.timer

• ✅ Added initialize_startup.sh for quick deployment and integration into Red Pitaya’s boot process

▶️ How to Run the Demo Every 30 Seconds

1. Wire the motor and Click board as shown in the image

   Motor Wires

   • Yellow → 1
   • Green → 2
   • Blue → 3

   Motor Base Wires

   • Blue → H1
   • Green → H2
   • Yellow → H3
   • Red → +5V
   • Black → GND

   External Power Supply

   • Ground → GND
   • Output → +

   Analog Pin Note

   • The analog pin should be wired to 3.3V (3v3) using the Terminal Click and a jumper, since only the AIN pin is routed to the Click Shield. The AN pin cannot be set to HIGH directly.

2. Power up your Red Pitaya

3. Connect to it via browser

4. Go to Development → Web Console

5. Log in as:

   • Username: root
   • Password: root

6. Run the following commands:

   git clone https://github.com/IvanRuzavin/RedPitayaClickShield
   chmod +x RedPitayaClickShield/initialize_startup.sh
   ./RedPitayaClickShield/initialize_startup.sh
   

🛠 Useful Commands for Debugging

# View logs for the systemd service
journalctl -u brushless.service

# View output from the script itself
cat /tmp/myscript.log

# Check the current status of the systemd service
systemctl status brushless.service
