#134869 - that depends Responding to: ???'s previous message |
No i don't have a schmitt trigger although it may not be a bad idea.
I would say a schmitt trigger is mandatory with that slow a risetime. At 1.5ms, i estimate even with processing time + service routine should not take more than 1ms? that depends what uC what clock speed how big is the ISR do you use any floating point is something in the main depending on results from the ISR if so is everything fully atomic so, once more complete imnformation, please |
