Compilation error when adding an assignment statement

[TechSavvySam]

I can declare a float value and use it returning the default value, but as soon as I add an assignment statement to my code I get a compilation error. I was developing on the cloud and had the problem and then I downloaded to my local IDE and have the same problem.

Here's the code:

float LowVoltageTrigger;
EEPROMStorage<float> permLowVoltageTrigger(0,12.2);
...
 permLowVoltageTrigger.set(LowVoltageTrigger);

Here's the error:

WARNING: library EEPROM-Storage claims to run on particle-photon, particle-electron, avr architecture(s) and may be incompatible with your current board which runs on renesas_uno architecture(s).

I'm guessing maybe you've only compiled this for Particle, which is why it won't even compile for Arduino.

It doesn't seem there's a way in the Arduino cloud to report issues with libraries, so I guess it's up to each person to try it to see that it doesn't work.

If you update it soon, I'll be glad to test the update for you to see if it fixes the issue.

The library was originally tested on an Uno and a Particle Photon. What board are you using? Looks like an Uno R4 Arm Cortex?

I confirmed this is failing on the R4 board. I'll take a look at the code and try to fix it.

Correct. Uno R4 WIFI

Any idea when this update will show up on Arduino Cloud? I'm new to Arduino so I don't know how often Github updates flow to Arduino Cloud. I'd like to test it so I can get feedback to you quickly.

I pushed a fix to the branch called v1.0.2. I do not have an Uno R4, but I did ensure it compiles. I reran my tests an a Mega and a Particle Photon and all tests passed.

I just saw that. Let me download that to my local IDE and test it. Then if it works, I'll let you know and you should mark it as supporting the R4

Thanks. I pulled v1.0.2 branch and tested on Arduino UNO R4 WiFi and it the code compiles and works.

The code has been merged and released. The Arduino library manager should pick it up within 24 hours.
