示例1: enumerateGIFFiles
// Enumerate and possibly display the animated GIF filenames in GIFS directory
int enumerateGIFFiles(const char *directoryName, boolean displayFilenames) {
numberOfFiles = 0;
// Set the current working directory
if (! sd.chdir(directoryName, true)) {
sd.errorHalt("Could not change to gifs directory");
}
sd.vwd()->rewind();
char fn[13];
while (file.openNext(sd.vwd(), O_READ)) {
file.getName(fn, 13);
// If filename not deleted, count it
if (fn[0] != '_') {
numberOfFiles++;
if (displayFilenames) {
Serial.println(fn);

}
}
file.close();
}
// Set the current working directory
if (! sd.chdir("/", true)) {
sd.errorHalt("Could not change to root directory");
}
return numberOfFiles;
}示例2: getGIFFilenameByIndex
// Get the full path/filename of the GIF file with specified index
void getGIFFilenameByIndex(const char *directoryName, int index, char *pnBuffer) {
char filename[13];
// Make sure index is in range
if ((index >= 0) && (index < numberOfFiles)) {
// Set the current working directory
if (! sd.chdir(directoryName, true)) {
sd.errorHalt("Could not change to gifs directory");
}
// Make sure file is closed before starting
file.close();
// Rewind the directory to the beginning
sd.vwd()->rewind();
while ((file.openNext(sd.vwd(), O_READ)) && (index >= 0)) {

// If filename is not marked as deleted, count it
if ((filename[0] != '_') && (filename[0] != '~')) {

}
// Set the current working directory back to root
if (! sd.chdir("/", true)) {

}
// Copy the directory name into the pathname buffer
