SDFileSystem example for the Wi-Go2 module
Dependencies: SDFileSystem mbed
Compile this program and upload it to your Wi-Go2 board. On a serial terminal program such as TeraTerm you can follow the progress.
After a succesfull it will have created a Wi-Go folder on your SD card, in it is a text file with some text. You can verify on for example your computer if it is there.
Note:
For some reason my SD-card refuses the first command, which is why the mkdir command is included twice. I believe the issue is my SD-card and not the Wi-Go board. If your SD-card behaves normal this extra command will not give you any problems. In case you also have the same issue there will be some error messages printed on your terminal. As long as it says "Finished" at the end the program completed succesfully.
