How to select micro controller architecture Depends on project requirements, developer familiarity and access to tools, and budget matters. Second sourcing used to be important, but not any more. If you're going...
OK, that SD card interface looks very promising. Many thanks!
Yeah, this may be the wrong approach (but USB drives are so convenient!). Maybe special hardware is a better choice. Then it needs other special hardware to program it...
It should work until it doesn't. How much time do you want to spend checking data sheets for any possible mismatch? How much time do you want to spend debugging when...

Lots of invisible code here, but I'd say your problem is as you suspect, reading the counter after any task has executed and still expecting % 10 == 0 to be true. Not...

The delay is about 200 * 256 * 3 (clock cycles per inner loop) * clock cycle time, or very roughly, 10 ms for the numbers you've used. It's possible that the interrupt...

In your case, putting a delay inside the ISR is the easiest solution (though not a good idea in general - ISRs should be short and fast as a rule). A second approach, ...
