One I want to say I’m really new at coding and havn’t coded in 2 years, but I have a new project that I want to start.
It starts with me reading in a folder in an SD and then a file within that SD and I will have multiple folders and files in the SD but all the same format.
I can’t seem to find any library that will let me use my internal SD card reader on my teensy. I know I can use the Arduino IDE + Teensyduino but I really like the Platform IO.
Does anyone know of a library I can use?
Let me know,
What exact problem do you have, in compilation or code?
The SD library is builtin to the Arduino-Teensy core package (this one, also see
C:\Users\<user>\.platformio\packages\framework-arduinoteensy\libraries). No need to get another one.
The example sketch also explicitly talks about which pin changes have to be made to use the internal SD card reader
When I use the
platform = teensy
board = teensy36
framework = arduino
with the file above as
src\main.cpp, with the changes
#include <Arduino.h> at the top
- changing to
const int chipSelect = BUILTIN_SDCARD;
|-- <SD> 1.2.2
| |-- <SPI> 1.0
|-- <SPI> 1.0

Wow thank you for the quick replay during my lunch break I will try and get this going.
During the quick read it seems like I have to download the SD library from Adafruit Industries on the platform IO IDE and then change the pins to make it work with the internal SD card reader.
I will read your replay in more detail later but thank you for a path forward.
Reread it carefully later, but you do not need to install any additional libraries, since the SD library is builtin to the Arduino-Teensy core package. In fact it would be harmfull to install another SD library that doesn’t fit the target board.
Hope you are having a good day Maxgerhardt,
I just wanted to let you know I was able to read the volume with the above example.
Next I’m going to figure out how to open the file and read from it. !
And also organize my code a little bit so I don’t have a big setup file in main.
