#166326 - slow processors Responding to: ???'s previous message |
Just a footnote - for people running original 12-clockers, it may be an idea to have a #define to run the ISR in 100Hz instead of 1kHz - either requiring the user to specify the delay in 0.01s steps, or let the user still specify the delay in 1ms steps, but let the actual delays tick 10ms at a time.
Not all projects requires 1ms resolution, and the instructions consumed by the ISR can be quite expensive if the processor is slow. |
