Incorrect Battery Percentage Reading on MKR 1010 with 3.7V Lithium Battery
Hi
I am using the following code to monitor a 3.7V 800MAH lithium battery to power my MKR 1010, and I have all the required library. However, this code always shows the battery percentage as 100, do you have any idea how to solve?
#include "Battery.h"
Battery battery(2750, 4200, ADC_BATTERY);
void setup() {
Serial.begin(9600);
while (!Serial);
analogReference(AR_EXTERNAL);
analogReadResolution(10);
battery.begin(3300, 1.47);
}
void loop() {
Serial.print("Battery voltage is ");
Serial.print(battery.voltage());
Serial.print(" (");
Serial.print(battery.level());
Serial.println("%)");
delay(1000);
}2 Replies
Hi Aymen can you add this to your code is for debugging purpose ; void loop() {
int rawADC = analogRead(ADC_BATTERY);
Serial.print("Raw ADC value: ");
Serial.println(rawADC);
Serial.print("Battery voltage is ");
Serial.print(battery.voltage());
Serial.print(" (");
Serial.print(battery.level());
Serial.println("%)");
delay(1000);
}
Could you please explain what difference it could make?
