Hi everyone, I found an easy way to read .log file by MATLAB. MATLAB has functions to read binary file but the difficulty is that we are not sure about the header and format of the log data. I am not familiar with Python so the other way that posted by benl using Python is such a pain to me. Here are a few lines that can easily decode .log file with two channels of data: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %% Read Data from OpenLogger file close all;clear;clc logfilename = '20190723_9_0.log'; finfo = dir(['F:\' logfilename]); channelNum = 2; %number of chan

Hi, I am trying to continuously log data. I have logged data to the SD card for more than 20 hours. The experiment result is pretty good: 1. the OpenLogger can continuously work; 2. it can split files automatically 3. the maximum size of a single file is about 3.7GB However, the time of each data file is wrong. Does the OpenLogger have any timing module? I have made it connected to the internet. Is it possible for it to adjust time according to the internet? thanks!

Hi JColvin, Thanks for your help! I made it this time! The main cause is that my SD card is wrong (64GB, exFAT). Even though I formatted this SD card into (16 GB, FAT32), it still doesn't work. The partition software is cheating me.... I finally borrow a real FAT32 formatted SD card of 32 GB from my colleague and it works well with the OpenLogger and WaveForms Live. Thank you so much! Peggy
