[SOLVED] Can't Seem to Program Arduino Uno

sjcastellano · April 20, 2016, 4:17pm

Hi Elco (or anyone else),

I am new to programming and this is my first BrewPi Community post. I have successfully installed the BrewPi web interface on my RPi. When I am trying to program the Arduino using the brewpi-arduino-uno-revC-0_2_10.hex firmware, I am getting the same error message as everyone else.

“Cannot receive version number from Arduino. Your Arduino is either not
programmed or running a very old version of BrewPi. Please upload a new
version of BrewPi to your Arduino”

I made sure I was using the legacy branch. I tried resetting the EEPROM using the code posted, as some have suggested. I tried different programming settings in the controller settings. I was going to try the Xloader option, but I am using a Mac. Nothing that I have read seems to work.

Any help would be appreciated!

Is your legacy branch up to date? Then the updater should be able to program your Arduino.

The reset EEPROM code does nothing if the Arduino is not programmed, it is a BrewPi specific command. In fact, it should not be used anymore, there is a button in the web interface to reset to factory defaults.

Ok. So I went back (again) and updated my legacy branch. I even tried the legacy_dev as you suggested to someone else. Currently back on legacy. This is what I get:

Then, went to BrewPi interface and reset controller to factory defaults under advanced settings. Finally, went to Reprogram Controller. Uploaded hex code as stated in earlier reply, chose Arduino Uno, and both settings were changed to NO. Went to Program the Arduino and this is what I get:

Thanks for your help!

The problem is that it cannot find a compatible serial device.

I have updated the code to print a better error message.

Please run: python autoSerial.py and check its output. It will list the available serial ports and show what it thinks is compatible.

sjcastellano · April 27, 2016, 4:14am

Here is what I got after entering the code:

python: can’t open file ‘autoSerial.py’: [Errno 2] No such file or directory

I’m guessing based on your description that my Arduino is not recognizing any serial ports.

sjcastellano · April 27, 2016, 5:04am

I can definitely confirm that I do not seem to have any compatible serial ports. Here is what I get when running:

sudo python /home/brewpi/autoSerial.py

All ports:
/dev/ttyACM0 - Arduino Uno, VID:2a03, PID:0043
/dev/ttyAMA0 - ttyAMA0, VID:None, PID:None
Compatible ports:
Selected port: (None, None)

Now I am just not sure where to go next. Searched boards for answers. No luck.

Elco · April 27, 2016, 12:40pm

What kind of Arduino do you have?

The problem is that your PID/VID is not in the list of compatible devices.

It is an official Arduino Uno R3.

Elco · April 27, 2016, 6:26pm

Ah, this is due to the ugly fight between Arduino/Genuino. The founders split the company.
Arduino.org uses the VID that you have. It is different from Arduino.cc

I have updated the script to recognize the Arduino.org VID too now.

brunoayub · May 2, 2016, 11:21pm

I have the same issue, but de output from autoserial.py is quite different.

python autoSerial.py
All ports:
/dev/ttyUSB0 - USB2.0-Serial, VID:1a86, PID:7523
/dev/ttyAMA0 - ttyAMA0, VID:None, PID:None
Compatible ports:
Selected port: (None, None)

is it possible to change anything in config files by my self?

Thanks!

UPDATED: I put one more line in autoserial.py and now both PI and arduino can talk

{‘vid’: 0x1a86, ‘pid’: 0x7523, ‘name’: “uno”}

sjcastellano · May 4, 2016, 5:02am

Everything works!!! That seems to have done the trick. Can’t thank you enough. Time to begin the trial phase.

sjcastellano · May 4, 2016, 5:03am

Were you able to get it up and running?

brunoayub · May 4, 2016, 12:36pm

Almost…
Now rapspi recognize the arduino, and I can flash it. But… when I go to the ‘Device Configuration’ and press ‘Refresh Device List’ (with read values checked), the temp sensors doesnt appear. I check circuit (i ran a simple code to get the address and values, was ok), check the logs, many times and nothing.

Elco · May 4, 2016, 5:36pm

Make sure the sensors are on pin A4
Make sure 5V is connected to the sensors, we ignore parasitically powered sensors, because they are not reliable.
Make sure you have a 4.7 kOhm pullup resistor. Not 1 per sensor, only one on pin A4.

brunoayub · May 9, 2016, 6:29pm

Nothing… :-/
Changed the resistor, the wires, the power (and also reinstall the raspbian). Both relay (ports 5 and 6) was recognized (sounds “click” when I add).

But the temp sensors doesnt apear. I think the port A4 of arduino isnt OK…

olywrestle · June 20, 2016, 7:03pm

I used the updater.py --ask like above and am on the legacy commit, but I am getting the following error when trying to program. This is a brand new clean install for 2 instances (clean linux install, and clean brewpi install). I have followed all the commands for running 2 arduinos. Any ideas?

olywrestle · June 24, 2016, 11:38pm

I found out I had to kill the brewpi.py processes before the autoSerial.py would take affect. Just in case someone else runs into this. sudo python /home/USER/brewpi.py --kill

Elco · June 25, 2016, 9:18am

Also make sure you only have one Arduino connected while updating.

JimWu · August 16, 2016, 5:16am

How did you edit autoserial.py?

olywrestle · August 16, 2016, 11:44am

Open terminal
cd /home/brewpi/autoSerial.py
sudo nano autoserial.py

That will open a text editor in the terminal window for you to make the needed changes.
