Hi Martin. I found on www a few weeks back ------------------------------------------ Two ways to measure the flow rate • Count the number of pulses in a known time period. • Time the period between two pulses. The first is easy and accurate but the more accurate you make it, the fewer measurements ...

What I have to do - I need to use the created by Timer1 time as the reference value and calculate the time duration between the two pulses from the paddle wheel from P-66. The more I think about it the clear I see the need to use c-code. I am busy right now with the different projects. Not sure when...

Many thanks mnfisher.
Will post results shortly.

Would be good. Thanks.

Thanks mnfisher I was thinking to stay away from c-code for a while. I am not sure if I can. --- Some suggest to set the Timer1 (Atmega328) to 1024 prescaler. 16 MHz / 1024 = 15625 Hz. 1/15625 = 0.000064 seconds 65536 * 0.000064 = 4.19 seconds. Where 4.19 is the Timer1 overflow duration (is it?) ---...

Hi
The duration between two pulses calculation question.
------------------------------------------------------------------
I have an AirMar P66 transducer.
Not a smart one, but the analogue one.
Has anybody read the paddle wheel speed from this transducer?
And maybe the depth sensor as well?
Thanks.

Thank you mnfisher
Was carefull with floats before. Will be more now.
Thanks again.

Thank you Ben. All good. Works now.

Floats and Atmega328 question.

Is it a good idea to use floats with Ard Nano?
I can use uint and insert the dot later on (to mimic the float).
Will it ease the load on Atmega328 and save the space in the memory if I stay away from the floats?

Hi
I have no problems reading the uint from Lut2.
Cannot read the floats from Lut1 for some reason.
Any help please?
