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 problem as I am. ...

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. if (count > 0) { // write to file ...

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 acquire both...

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.
