MegunoLink

Hi, earlier this year i built a project using my arduino, pressure sensor and the megunolink to measure and monitor a pressurized tank and it worked great. Recently i built another pressure tester and i tried to compile the exact same code into the sensor and it errors from the megunolink library. Has something changed in the driver that would cause a sketch from say march to not compile?

this sketch always compiled without issue, now it errors.

Hi Goho,

I noticed you also have a library called "Time-master" in the build output. My guess is that there is a conflict with that library and the built-in "time.h" library we are using. That could happen if the "Time-master" library has a file named "time.h" too (it could override the system one).

To resolve, you could rename time.h in the time-master library to something else, propagating that change to any #includes in other files in the time-master library. I found a few Arduino time libraries so I'm not sure which one you are using. If you could post a link to it we might be able to figure out a different solution.

It looks like support for sending time values with our plotting library was made in January this year. So likely is the problem.

Have a good day

thanks, ill check that but it didn't error before so im thinking maybe an updated library was the issue.

I have a pressure tester that is working right now using that exact code but now it wont compile....

thinking what might have changed, the only thing i updated since i last compiled this sketch was Megunolink. i have not updated the Arduino IDE or and library so the issue must be in an update from Megunolink.

i updated the Time library and it compiles ok. Problem solved!

The new 'error' was definitely my fault as I added a new feature to our Arduino library (to include time values when sending data to our time-plot visualizer). Glad you were able to resolve the conflict with an update to the time library. Thanks for letting us know!

Have a great day
Paul.
