I’ve been digging around in the docs but haven’t seen anything about it yet. I’d like to know when the electron is running on battery or when is the electron’s battery being charged. Is there anything in the library showing this? Tony

Here is a sample of some of the code that i am trying to use, just including the parts that are causing trouble and have to deal with the PMIC commands: PMIC pmic; void setup() { pmic.begin(); // initiializes the PMIC (power management chip) so that system status informait…

Those functions aren’t implemented. It’s a bug. But you can easily work around it because those are just elements of the pmic.getSystemStatus() value. But it won’t actually help, for reasons I’m about to post…

This is a deceptively difficult thing to detect. I’m not sure the method here is the best way to do it, but this is the first method I’ve found that actually produces the correct result, so there is that. I believe the problem is that when there’s no battery, the PMIC doesn’t go into some easy-to-r…

Thanks for putting that together. It seems like it should work for my purposes, and hope that it solves some problems that other people have as well. One comment though, it seems like the PowerCheck() function needs to be running continuously to be able to get the readings from the system status …

I wouldn’t use powerCheck.loop() from a timer because it calls I2C and I2C is not reentrant. At least I don’t think I2C is. I’ll write the interrupt-based version of this code which is a much more efficient way to do this, anyway. I probably won’t get a chance until next week, after the 4th of July …

This version is much better. It uses the BAT_INT_PC13 interrupt to detect the rapid switching between fast charge and charge done when there is no battery. It’s much more efficient and doesn’t require being called from loop. You just initialize it once and use the getHasBattery() method to find out…

Thank you! @rickkas7 - it works perfectly :slight_smile:

LOW_BAT_UC isn’t found Has it been deprecated, or did I miss a #include ?

For me this builds. Have you got an Electron selected as target? What system version are you targeting on that Electron?

The battery interrupt code above is built into device OS now, and it's much better to get the is battery powered state from device diagnostics. This code can be used instead of the code above:
