After playing with an AUTONOMO for a few weeks i just want to share in one post some snippets of code and info i’ve been gathering around that will help you save some time!. The idea is to update this as much as i can. Got any questions? let me know!
- READING BATTERY VOLTAGE
//These constants are used for reading the battery voltage, you will get one serial post every 5s
#define ADC_AREF 3.3
#define BATVOLTPIN BAT_VOLT
#define BATVOLT_R1 4.7
#define BATVOLT_R2 10
Void Setup()
{
}
Void loop()
{
SerialUSB.println((String)GetBatteryVoltageMV());
Delay(5000);
}
float GetBatteryVoltageMV()
{
uint16_t batteryVoltage = analogRead(BATVOLTPIN);
return (ADC_AREF / 1.023) * (BATVOLT_R1 + BATVOLT_R2) / BATVOLT_R2 * batteryVoltage;
}

SerialUSB.println(retval); SerialUSB.println("GET result: ");
//Lets be safe in case result length > 247 for (int i=0; i<strlen(buffer); i++) {SerialUSB.print(buffer[i]);
