Dodajanje pravic naprave med uporabnike

Do naprave ‘/dev/ttyACM0’ navadno ne moramo dostopati ter tako ne moremo programirati Arduino krmilnika. Napravo lahko dodoamo tako:

ls -l /dev/ttyACM*   > crw-rw---- 1 root dialout 188, 0 5 apr 23.01 ttyACM0

sedaj dodamo našega uporabnika da lahko upravlja s to napravo "dialout"

sudo usermod -a -G dialout <uporabnik>

ARDUINO WAVGAT

  1. Start Arduino IDE and open “Preferences” window from “File” menu.
  2. Go to “Additional Board Manager URLs” field add this url: https://raw.githubusercontent.com/paraplin/wavgat-board/master/package_paraplin_wavgat_index.json and press OK.
  3. Go to “Tools” menu and select “Open Boards Manager”. In the new window install wavgat platform.
  4. Go to “Tools” menu and go to “board” submenu. Select your correct board in “WAVGAT boards” section.

Arduino USB povezava - Linux

  1. ko priljučimo Arduino na USB, se v /dev/ pojavi file /dev/ttyUSB0

     ls /dev/ttyU*

  2. preverimo lahko tudi, z ukazom lsusb nekaj več podatkov o napravi Naprimer najprej pregledamo vse usb naprave:

Arduino as programmer

  1. Na Arduiono programmer naložimo:

ArduionoIDE -> Examples -> ArduinoISP

  1. Povežemo programmer in targer vezje:
Sigmnal Arduino programmer ISP Connector
MISO D11 1

Preverjanje krmilnikov Arduino UNO

  1. Preverimo, če deluje integrirano vezje CH340 za USB->UART komunikacijo:
    1. povežeš PC in krmilnik UNO, ter preveriš, če je zaznana nova naprava na vratih za serijsko komunikacijo.
    2. odpreš Serial Monitor in pošlješ nek znak: na krmilniku UNO mora uripniti ledica za TX
    3. preverimo povratno UART komunikacijo = PC->CH340->PC:
      • onemogoči mikrokrmilnik ATmega328P = povežeš RST -> GND
      • kratko skleneš nožico 2 in 3 na CH340 (z izvijačem ali priključkom M-metra)
      • v Serijski Monitor vpišemo nekaj znakov in le-ti se morajo izpisati nazaj na PC
  2. Preverimo delovanje mikrokrmilnika ATmega328P:
    1. s programatorjem ArduinoISP preverimo signature byte
    2. s programatorjem ArduinoISP poizkusimo naložiti Blink
    3. s programatorjem ArduinoISP naložimo Bootloader

avrdude: stk500_recv(): programmer is not responding

Opis napake: Arduino Uno se ne da sprogramirati. Vrne napako :avrdude: stk500_recv(): programmer is not responding.

Check lista:

  1. Če se povežeš na serijsko vodilo (USB->UART) in pošlješ iz PC -> UNO nek text, ali ledica Rx nutripa?
  2. Če povežes RX in Tx na UNOTU in pošlješ nek text ali obe ledici utripata?
  3. Ali s programatorjem ArduinoISP lahko prebereš SighnatureByte 1E950F - ATmega328P?
  4. Ali lahko s programatorjem ArduinoISP sprogramiraš krmilnik Arduino Uno?
  5. Z drugim krmilnikom UART pošlji podatek na nožico Tx… in se mora na računalniku pojaviti ta podatek?
no Opis testiranja 11 12 13
1. ATmega328P signature byte read by ArduinoISP programmer? YES    
2. Program with ArduinoISP programmer? YES    
3. Program bootloader with ArduinoISP programmer? YES    
4. CH340 prepoznan? YES NO NO
5. PC->CH340 = TX Led blinking? YES    
6. PC->CH340->TX->—–>RX = LED is blinking? YES    
7. Delujoči UART.Tx->UNO.Tx->CH340->PC? NO
