Hello,
Have you tried your camera with an Arduino to see if it’s functioning correctly?
Edward
Hi,
I don’t have Arduino.
I’m trying to determine if there might be an issue with your Pixy hardware. If you test your Pixy on an Arduino and everything is working, it might help you narrow down the problem.
Edward
Hi,
Give me a link to the basic Arduino tests.
Hey Walt, try the instructions here: https://docs.pixycam.com/wiki/doku.php?id=wiki:v2:hooking_up_pixy_to_a_microcontroller_-28like_an_arduino-29
Thanks,
Jesse

I don’t understand what they’re doing there…
Hi,
I rebooted my PC, opened up the ccc_hello_world example, plugged in the Arduino UNO to the USB, the program passed the check, but when I did an download to the Arduino UNO I got this message;
Arduino: 1.8.12 (Windows 10), Board: “Arduino Uno”
Sketch uses 7494 bytes (23%) of program storage space. Maximum is 32256 bytes.
Global variables use 508 bytes (24%) of dynamic memory, leaving 1540 bytes for local variables. Maximum is 2048 bytes.
An error occurred while uploading the sketch
avrdude: ser_open(): can’t open device “\.\COM14”: The system cannot find the file specified.
This report would have more information with
“Show verbose output during compilation”
option enabled in File -> Preferences.
So then I plugged in the PIXY2 USB and got this error;

Problem uploading to board.
See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with
“Show verbose output during compilation”
option enabled in File -> Preferences.
Hey Walt,
please try changing your serial ports in the “Tools/Serial port” menu. Or, if you’ve got anything plugged into pins 0 or 1 on Arduino, unplug it until you’ve uploaded the sketch.
Cheers,
Jesse
Hi,
Nothing plugged into the Arduino UNO except the USB cable to the PC on COM5 …
Error Msgs;

Something is up with the serial port. When the IDE is trying to connect in order to upload the sketch to Arduino, it can’t find the port. Check your serial ports in the “Tools/Serial port” menu.
Hi,
I’d rather get back to the PICAXE and BASIC programming. The UNO does the “BLINK” program okay, so I’m sure it works okay with my PC, but I need the camera to work with my PICAXE chip.
Hey Walt, I don’t know what the “BLINK” program is. We’re trying to test and make sure Pixy is working normally with regard to sending data over serial. Since the Arduino is a known factor for us, it would help if you could try the “hello world” code we provide in the Pixy Arduino library and verify that everything is working correctly.
I understand that you are working with the PICAXE. Since we don’t offer direct support for that controller, we are doing our best to help out in whatever way we can.
Thanks,
Jesse
Hi,
I tried the LED “BLINK” program to be sure the Arduino UNO was working and it does work. But I cannot get the PIXY2 to work with the Arduino UNO. I did manage to get the software loaded, and made sure the com port speeds were as directed by the software.
OK, thanks. What’s not working with Pixy2 and Arduino? What are you trying?
Getting Pixy2 and Arduino working together is a good litmus test for other connections.
Thanks,
Jesse
Hi,
Okay, got back to the project and did it step by step taking print screens to show what’s going on;
I have the Arduino connected to USB to Windows 10
I have the PIXY2 connected bia the gray cable to the Arduino end connector … Red 1 towards Digital side RX <-0
I also have the PIXY2 connected via USB to Windows 10
First set of images is the PIXY2 camera settings;
Next is the PIXY2 wiki with the wrong file name for the libraries;
Next is showing the results at the 115,200 BAUD rate;
Next is setting both the PIXY2 and the Arduino to 9600 BAUD;
Pretty much I’m not getting any communications.
I do not know what to try next.
Hello,
Unless there is something like plugging in the cable backwards into Arduino (see https://docs.pixycam.com/wiki/doku.php?id=wiki:v2:my_arduino_isn-27t_receiving_data_from_pixy) it does appear that the SPI port on Pixy is not working.
We will contact you.
Edward
Hey Walt, I’m contacting you directly.
Hi,
I got the camera today, hooked it up and yeah, it’s working with the Arduino UNO.
Now I need to figure out how to get it to communicate with the PICAXE 28X2 module;
I plan to start with using the hserout and hserin pins … then when it’s working I can switch to the serin and serout pins after the whole program is working in a robot.
First question is which PIXY2 PINs to connect to the PICAXE 28X2 module?
Second question is what baud rate do I set for the PICAXE 28X2 module?
