Hi Oliver, OK, so it will be mm (word) and mil (dword). Sample output looks like this, see below. This is not yet with a module since I did not yet get it. I used another PIC to simulate the module.
Distance measured is: 25 mm or 1010 mil. Distance measured is: 2.5 cm or 1.0 inch. Distance measured is: 34 mm or 1350 mil. Distance measured is: 3.4 cm or 1.3 inch. Distance measured is: 58 mm or 2290 mil. Distance measured is: 5.8 cm or 2.2 inch. Distance measured is: 81 mm or 3180 mil. Distance measured is: 8.1 cm or 3.1 inch. Distance measured is: 95 mm or 3750 mil. Distance measured is: 9.5 cm or 3.7 inch. Distance measured is: 103 mm or 4060 mil. Distance measured is: 10.3 cm or 4.0 inch.

Question about the mils. The modules resoluiton is limited (see screenshot below). What would 1/000 of an inch bring? Is it because of the standard terminology mils? [cid:Td1Ro5YW9BV93yihGG4h] So your suggestion would be the following? function hcsr04_get_distance_mm() return dword is function hcsr04_get_distance_mils) return dword is Thanks.

I never use floats, so if I would have a function called "fine", it would return a length in mm (metric) or mils (=1/1000 inch imperial) Even if you would return a length in micrometers, a dword would suffice for a range of over 4 kilometers, still by a smaller overhead than using a float. Greets, Kiste Am Samstag, 30. September 2023 um 11:11:37 MESZ hat Rob CJ <[email protected]> Folgendes geschrieben: Hi Vasile, Thanks 🙂 I just came up with another idea. Using a float value makes the library big in ROM size (it easily adds 600 byte of ROM or more) and I only need one decimal. So I have another idea and that is return the distance in mm. In that case I only need a word as return value. So now I have only two functions: function hcsr04_get_distance_mili_meter() return word is function hcsr04_get_distance_mili_inch() return word is I only do not know if mili-inch is an English term. Would like to know that. Or should I use tens_of_cm and tens_of_inch? Thanks.

I am working on a library for the HC-SR04 ultrasonic ranging module. I have functions that return the distance in cm and inch. My question is the following. One of the functions returns a word so the distance is without a decimal, so 2 cm, 5 inch, etc. The other function returns a float so the distance is with a decimal, so 3.5 cm, 5.1 inch. I am looking for a good name for these functions. I now have the following names but I am wondering if there is a better name for them: function hcsr04_get_distance_cm_coarse() return word is function hcsr04_get_distance_inch_coarse() return word is function hcsr04_get_distance_cm_fine() return float is function hcsr04_get_distance_inch_fine() return float is So I am looking for a better name for these functions. Any suggestions? Thanks. Kind regards, Rob -- You received this message because you are subscribed to the Google Groups "jallib" group.
