Arduino Data Logging Speed at Logan Macartney blog

Arduino Data Logging Speed. It requires a 32.768 kohm crystal oscillator to keep accurate time, and this is sometimes sold together with the chip. Basically set up a timer to read the sensor every millisecond and place the data in a buffer. That gave the value of the sampling time, the time it took to write to the sd card and the time it took to get the real time from the rtc. The data that is logged to the micro sd card can be anything. For an arduino uno, the top speed is 1 mb/s of raw i/o; With the mega the spi clock can be set to 8mhz, i have never actually it at 8mhz, i just use the default 4mhz, so with a 23lc512. We would want to write () the data in each cycle, but we only need to flush (). Millisecond log times are entirely doable with an sd card, nanoseconds are entirely impossible. Typically, the battery will last for years. I used the arduino uno timing commands (“millis”) to measure the time required by each part of the code (see commented lines in the code). On a good day sd cards can write a few hundred kb per second (my experience.others. By using the backup power, the chip will keep time even if you remove the shield or if you unplug the arduino. According to fat16lib, to increase the data rate we need to use flush () wisely. You will want the coin cell battery as a back up. You should consider buffering the sensor data.
