Topic: SDFat - how to open 1 file close it and then open another (Read 237 times) previous topic - next topic


I am using SdFat and reading data from one file and then closing that file.

I then attempt to open another file and read data from it but I get a "File not found" error.

If I comment out the first file read, and make no other changes, the second file open and read works perfectly. Thus this is not a case of the file name being incorrect.

I have searched google and the forums but have not found an example of how you can open one file / close it, and then open the another file.

I am using the command

bmpFile.close(); to close out the first file before attempting to run this code:

  // Open requested file on SD card
  if ((tftFile = sd.open(filename)) == NULL) {
    Serial.print("File not found");

At which point I get the File not found error.

Thanks for your help.


You posted a snippet of code, so I'll post a snippet of an answer.
