You either poll, or you use an interrupt. Since both interrupt inputs are dedicated on the single injector signal, it must be checked by polling. Whether the polling takes place at a specific point in code, is triggered by an event scheduler, or is triggered by a hardware timer-based interrupt is irrelevant. It's still time-limited and subject to the situation I believe we're seeing here.
Perhaps you could make some
useful contribution to this thread by explaining
why I'm wrong, rather than slinging defensive, derogatory comments.
