Other Parts Discussed in Thread: ENERGIA
Hi there,
im pretty much starting from the scratch when it comes to MCU's and programming. At the moment Im playing around with my MSP-EXP430FR6989 and a simple DHT22 reading temp. and humidity.
Actually I was wondering how to store the incoming serial data with an additional timestamp e.g. on the board (FRAM?)?
I currently read the data on port 11 with the following loop:
void loop() {
delay(delayMS);
sensors_event_t event;
dht.temperature().getEvent(&event); /* Read temperature value */
if (isnan(event.temperature)) { /* If temperature value is not a number */
Serial.println("Error reading temperature!");
}
else {
Serial.print("Temperature : ");
Serial.print(event.temperature);
Serial.println(" *C");
}
dht.humidity().getEvent(&event); /* Read humidity value */
if (isnan(event.relative_humidity)) { /* If humidity value is not a number */
Serial.println("Error reading humidity!");
}
else {
Serial.print("Humidity : ");
Serial.print(event.relative_humidity);
Serial.println("%");
}
}
ps: I dont need a high sample frequency and also dont need to store data for a long time.
Regards
Hendrik
