  1. How to improve frequency sampling in Teensy 3.5 for saving data with SD card?

    Hi, I have previously posted a post asking how to save sensors data (EMG and Encoder) using a built in SD card reader in Teensy 3.5. I'm using this code below


    #include <SoftwareSerial.h>...

    Hi, so I had help from a friend and have found a way to save to the SD car while also having a stable frequency rate. I would like to share it with everyone just in case someone encounter the same...

    Hi, it's okay. I can wait and while at it, I will find other ways. I think I will try to compare with the previous code that works.

    Okay, thanks. It's more clearer now and I've changed the code. There is no error when I compiled it but I tried printing the sensor values using the code below.

    Where should I paste this? I have tried running the first code with the previous code you shared and the error is that FIFO_SDIO was not declared.

    I have tried your code but there's an error in #define SD_CONFIG SdioConfig(FIFO_SDIO). Is that a library that I need to download? Where can I download it?

    I was expecting a sampling rate that can...

    Thank you! Your suggestions work! Just a quick question, is there a way to add an id and a column title? I am also wondering if using an SD card to record a data would have a fix frequency sampling?

    Nothing happens when I try to comment my serial.print in the loop function and tried the code that you suggested. The serial monitor didn't show anything.

    Hi, thank you for your reply. I realized that the dologger() function is not right. But I had seen it from a forum, he said that it works for him. I thought it would work for me too. Is there any...

    I see, thank you for the suggestion. I will keep that in mind. Actually I should have establish EMG as an integer since the sensors reading didn't have any decimals.
  11. How To Maintain Frequency Sampling in Data Acquisition Using Teensy 3.5 and Saving it

    I have an ongoing project using Teensy 3.5 as a DAQ and I would like to acquire values of two sensors and its time stamp/ millis(). The sensors I'm using is Olimex Shield-EKG/EMG Rev. B for my EMG...

    Thank you for replying. I've tried your code but it doesn't have any effect. It was saving empty csv files instead and there were a lot of it. When I run your code, I have this warning.

  13. Using Teensy 3.5 Built-in SD card reader for data acquisition

    Hi, I am trying to use Teensy 3.5 to write data that I acquire from two sensors (encoder and an EMG). I found that there are previous forum mentioning about this too and I've also tried it. I tried...
