#173769 - Can't do it without assembly. Responding to: ???'s previous message |
C gives no guarantees on how exactly created assembly will do what the source code states. Theoretically, the compiler could insert random NOPs in the code if it feels like it. If you need cycle-exact delays, assembly is the way to go.
If you demands aren't that strict, using a timer (or other otherwise unused peripheral that can measure time) should work. This can be done in C. |
