- ARDUINO WIRE LIBRARY WARNING SERIAL

- ARDUINO WIRE LIBRARY WARNING TV
I know there are ‘fixed’ versions floating around on the internet, but I am having a hard time finding one that is up to date – does anyone know of a good one? If we cannot find and fix the root of the problem, we could try to work around it by creating a timeout within the Wire library. I have also heard complaints online of there being a flaw in the Wire library (while loops with no timeout) that allows this sort of thing to happen, but it seems mostly to be related to multi-master systems, so I don’t even know if that’s it.
ARDUINO WIRE LIBRARY WARNING CODE
At one point I thought there might be an issue with communication between the new code in the head and the pre-1.0 code in the base, but when we replaced the other Arduino as well and put in new code, the problem did not go away. The two main Arduinos are about 5 feet apart, so it could be a hardware issue, but that doesn’t explain why the old code works. So… I guess what I am asking is, does anyone have any idea what I might be doing wrong? We can’t find any problems with the code, and it will run for thousands of cycles at a time with no trouble. It also seems to get worse when the face controller is connected.
We suspect it has to do with I2C, because it tends to hang right around when it is sending a signal to the motor controller and getting a response, but it’s not consistent exactly where it stops, and again, we haven’t been able to find a consistent cause – we just press buttons and hope it freezes.
ARDUINO WIRE LIBRARY WARNING SERIAL
It is very difficult for us to replicate the problem, but the times that we have managed, we discovered that the master Arduino will hang up indefinitely and stop providing serial output.
ARDUINO WIRE LIBRARY WARNING UPDATE
However, every time we try to update the code in the master to a new version (by replacing the Arduino – we don’t want to destroy the only working code), the folks who operate the robot on the weekends complain that it ‘freezes’ intermittently, such as every 10-15 minutes or so, requiring it to be turned off. This means my mentor and I can’t add features, such as the new face, unless we update the code.
While the original code (written by my mentor) seems to work just fine, we don’t actually know exactly which version is in there since it has no serial output and we lack documentation, but we suspect it dates back a couple of years. I’m fairly new to Arduino and this is only my second project, but my much more experienced mentor hasn’t been able to find a solution either, and it’s been a few months now.Īnyway, the two to three Arduinos are connected via I2C, with the main one in the head as master and the others as slaves. I am working on adding a third Arduino, also in the head, to control newly created facial expressions and make the new LED mouth blink when it talks, but that is secondary right now until I fix the problem I’m about to describe. It also has speakers that relay the voice of another operator with a microphone, but that is almost entirely a separate system.
ARDUINO WIRE LIBRARY WARNING TV
The robot has two Arduino Unos, one inside its head which receives and interprets infrared signals from a TV remote held by its operator, and one in its base which translates those numeric signals into movement commands.
I am a volunteer at a science and technology museum, trying to work on improving their mascot ‘robot’ by adding some new features and updating its code. The reason it took me so long is that I had to wait for feedback from the operators, as described below. I’ll repeat the background info from that post, and then get into why I’m posting again. I made a very similar post to this one two weeks ago, trying to fix this same problem, but the suggestions I got, while useful and worthwhile, didn’t seem to work.
