If you use the write once option for an SD card you get what you asked for. If you use the ASSD features of an SD card same thing. The...

Enabling secure features for a card is protected by the OS kernel. Once enabled access is protected by the card's security processor. If you use a card in a non-secure...

So what? ``` int n; n = strlen("abc"); void setup() { // put your setup code here, to run once: } void loop() { // put your main code here,...

Yes there are conflicts in Teensy. It's best to use the Teensy wrapper for SdFat. You could try the github version of SdFat but you must use a more basic...

It's becoming difficult to write compatible programs that access SD cards on all Arduino like boards. I wrote the first version of SdFat at the end of 2008 for the...

At this point I accept that SdFat will have conflicts on many systems. I will just tell users too bad you can't use SdFat or maybe some of its features....

That sounds like the good simple solution. I never guessed SdFat would be around after so many years. It started as a toy I threw together without much thought for...

The RingBuf class can be used for read or write. The problem with SD cards is that they are not designed for multiple data streams. The are designed for a...

You need to experiment with transfer sizes. In the bin to csv example I used big reads and waited till the buffer was empty since this gave the best performance...

It's too bad SD cards are not better documented. The internals are trade secrets. I bought about 20 cards and wrote programs to classify these for various use. I gave...
