Custom PMIC settings for Monitor One

[jzalar]

I am not sure if I am doing something wrong nor right with respect to Power Manger settings. I am trying to increase the min. power source voltage so my 12 v (350ma) solar panel will charge the battery and not go into the low voltage state (flashing red on the chrg light). So my questions that I could figure out on my own are.

1. Does the "SystemPowerConfiguration conf" go into void setup () or void start up ()?
2. Do you need to call "PMIC power(true);" in void loop ()?
3. Is there are way to verify the setting with a location call back. (I tried putting PMIC power(true) in the call back and it unit stopped working)?

I am also using Vin on the main board and not one of the expansion boards.

Thank you in advance.

Here is the code below.

#include "Particle.h"
#include "Arduino.h"
#include "edge.h"
#include "SparkFun_ADS1015_Arduino_Library.h"

    Edge::instance().init();

1. Setup is good.
2. See below for an example.
3. From docs:

void loop() {
{
PMIC power(true);
Log.info("Current PMIC settings:");
Log.info("VIN Vmin: %u", power.getInputVoltageLimit());
Log.info("VIN Imax: %u", power.getInputCurrentLimit());
Log.info("Ichg: %u", power.getChargeCurrentValue());
Log.info("Iterm: %u", power.getChargeVoltageValue());

    int powerSource = System.powerSource();
    int batteryState = System.batteryState();
    float batterySoc = System.batteryCharge();

    constexpr char const* batteryStates[] = {
        "unknown", "not charging", "charging",
        "charged", "discharging", "fault", "disconnected"
    };
    constexpr char const* powerSources[] = {
        "unknown", "vin", "usb host", "usb adapter",
        "usb otg", "battery"
    };

    Log.info("Power source: %s", powerSources[std::max(0, powerSource)]);
    Log.info("Battery state: %s", batteryStates[std::max(0, batteryState)]);
    Log.info("Battery charge: %f", batterySoc);
}

Thank you. It seems to be working. Is there any risk with inserting PMIC Power(true) into mylocationGenerationCallback? I wanted the battery and charging information to be part of the loc callback when I put the unit to sleep.

Thanks

Jon

You should be able to do that from the location generation callback.

I was able to add those to the my location callback. Thanks for all the help.
