6/19/2023 0 Comments Arduino mapI doubt, that I would have been able to wrap my head around things like shifting registers, bit logic and the likes, without starting at the shallow end in the first place. The more things I build with tools like Arduino or Processing, the more I learn about "eloquent" ways of getting things done. I am not aiming to become a programmer, but am grateful for the opportunity to easily build my own hacky prototypes to illustrate an idea or build a temporary solution for an exhibition or other kind of presentation. Now, the more I stare into the abyss that is "actual programming", I can improve on my coding skills - ’though I guess my programming "skills" will never make it into a real production environment. However: When I started dipping my toes into the shallow waters of Arduino and working with micro controllers, I was glad to find a lot of libraries and helper functions like map() etc. Anyone can do it.Ĭode: template long map(T _x, A _x_min, B _x_max, C _out_from, D _out_to, typename std::enable_if::value >::type* = 0) and uniform random integers within a specified range are generated by Heck, even a six year old can cut with a knife, who needs a decade of education just to do a heart bypass. well, as foolish as thinking: well, start as a janitor at the hospital, work hard, get promoted to "orderly", then in time, get promoted as nurse, then promoted doctor, then heart surgeon. ![]() No doubt there are a few 10 year-olds who knows more math than most college grads can ever dream of, but to merely assume that math and other basics are irrelevant is. No wonder programmers are getting no respect these days. The talking heads on the show was amazed at how programming was easy and that kids would in no time be making 6 figures automating everything. The waiting room TV was showing a Microsoft elementary school project working with what appears to be 3rd/4th graders "programming" by (using some Microsoft developed tools) dragging cartoon icons around to make a "working application". It was just around the time when software became suspect for that LION air crash, just around that time I was at a tire-repair store waiting on some tire work. * *** */ I said deadly in the first paragraph, there is a reason. it will even help in understanding cooking recipes. If one can't answer that question, learning more math will help with understanding EE, politics, economy, history. * *** */ If you can answer this question, you don't need the map() function: In a class of 1234 students, 6.7% passed how many student passed? That is to "map" 6.7% from 100 (definition of percent) into 1234 (actual sample). It has been as successful and as deadly as "easy ways to do heart surgery for DIY'ers". In addition to the map function, we can also use a function called constrain to limit an input within a specified boundary.(I think this exceeds the normal definition of a reply and drifted into the "rant" category) I think "map" function is a misguided attempt to make programming "easier" for everybody. #fuses HS, PUT, NOWDT, PROTECT, CPD, NOBROWNOUT, NODEBUG, NOLVP, NOWRT ![]() Here's the code for map function in CCS:ĭouble map(double value, float x_min, float x_max, float y_min, float y_max) ĭouble map(double value, float x_min, float x_max, float y_min, float y_max) However it can also be used to interpolate non-linear relations by calling it with different ranges for different segments. ![]() The limitation of this function is it only works in linear scales. ![]() In such cases the map function does this scaling for you. For example you wish to scale 0-1023 count of an ADC to 0-5 volt range or take a value and represent it in some other scale which is much more easy to understand. It simply scales an input to a desired output scale. In Arduino there's a very useful function called map. Please do not post bug reports on this forum.
