Test programs:
Python program for measuring response time
import time
import serial
def millis():
return int(round(time.time() * 1000))
ser = serial.Serial('/dev/ttyACM0', 9600)
while True:
start = millis()
data= "recv: "+ser.readline()
end = millis()
print (end-start)
print data
Time precision benchmark
void setup() {
Serial.begin(9600);
}
void loop() {
while (true) {
unsigned long start = millis();
delay(60000);
unsigned elap = millis() - start;
Serial.println(elap);
}
}
