- I used micros() to obtain the time delay with each loop, and found out that it is below 100Hz (I am expecting faster since it is a 8Mhz processor, and sensor is giving 1000Hz of readings). I need the Serial.print() cycle for every loop to be at least 100Hz. Is my method correct?
You are wasting a lot of time converting the int values to strings, sending the strings, and (on the other end) converting the strings back to values.
Using Serial.write() to send the high byte and then the low byte will be faster. A lot faster.
Could it be that I am polling my sensors fast enough, but Serial.print() made it slow?
Exactly.
