#134867 - looks clean, a little spark i suppose Responding to: ???'s previous message |
No i don't have a schmitt trigger although it may not be a bad idea. 6us
I compare it with my input capture and it triggers pretty clean at my micro controller too, the most delay i have seen is at max 25us (ie: it can take upto 25us before the input capture captures the rising edge) At 1.5ms, i estimate even with processing time + service routine should not take more than 1ms? |
