# Raspberry Pi tõrkeotsingu juhend
|
|
|
|
See juhend pakub lahendusi tavapärastele probleemidele, mis tekivad IoT projektide käivitamisel Raspberry Pi seadmetel.
|
|
See on mõeldud algajatele, kes kasutavad IoT-Algajatele õppekava, kuid on kasulik ka üldiseks Pi arendamiseks.

## 1. Paigaldamis- ja sõltuvusvead
|
|
|
|
### ❗ `ModuleNotFoundError: No module named 'xyz'`
|
|
See juhtub siis, kui vajalikud Pythoni moodulid ei ole paigaldatud.
|
|
|
|
**Lahendus**
|
|
```bash
|
|
pip3 install <module_name>
|
|
|
|
Permission denied when running scripts
|
|
|
|
Often caused by accessing GPIO, I2C or system hardware without elevated privileges.
|
|
Quick fix:
|
|
sudo python3 script.py
|
|
|
|
Recommended fix (no sudo needed every time):
|
|
sudo usermod -aG gpio,i2c,spi $USER
|
|
sudo reboot
|
|
|
|
2. GPIO / I2C / SPI Not Working
|
|
❗ RuntimeError: No access to GPIO
|
|
|
|
Add user to GPIO group:
|
|
sudo usermod -aG gpio $USER
|
|
sudo reboot
|
|
|
|
❗ I2C / SPI devices not detected
|
|
|
|
Enable interfaces:
|
|
sudo raspi-config
|
|
→ Interface Options
|
|
→ Enable I2C / Enable SPI
|
|
|
|
Check if I2C device appears:
|
|
i2cdetect -y 1
|
|
|
|
3. Camera / Video Issues
|
|
❗ Camera not detected or fails to start
|
|
|
|
Enable camera interface:
|
|
sudo raspi-config
|
|
→ Interface Options → Camera → Enable
|
|
sudo reboot
|
|
|
|
Check if camera is visible:
|
|
vcgencmd get_camera
|
|
|
|
4. Wi-Fi / SSH / Connectivity Problems
|
|
| Problem | Fix |
|
|
| -------------------------------- | --------------------------------------------- |
|
|
| SSH connection refused | `sudo raspi-config → Interface Options → SSH` |
|
|
| Device not showing on network | Check IP using: `hostname -I` |
|
|
| Slow Wi-Fi / unstable connection | Prefer 2.4 GHz band, update OS |
|
|
| Unable to access Pi headless | Add `ssh` file to boot partition |
|
|
|
|
|
|
5. Performance Issues
|
|
Raspberry Pi running slow / laggy
|
|
|
|
Close unused applications
|
|
|
|
Reduce background services
|
|
|
|
Use Lite OS if no desktop needed
|
|
|
|
Ensure sufficient power supply (5V/3A or better)
|
|
|
|
Check CPU load:
|
|
top
|
|
htop
|
|
|
|
Storage issues:
|
|
sudo apt autoremove
|
|
sudo apt clean
|
|
df -h
