Title: IF-THEN Post by: masterj on June 29, 2012, 06:16:12 AM Hello :)
Quick question here: What happens if before "if-else" condition comes FALSE (0) (please look at the attached image)? If it were TRUE then mslcorr_w variable would get value of 1, but if there's FALSE condition what happens then with this variable?

Title: Re: IF-THEN Post by: RaraK on June 29, 2012, 07:50:44 AM Yea, since it appears to be a boolean operation, the value can only be a 0 or 1 to the variable.
You can check this by searching for that variable and see how its used in other function, if its output is to a switch than this will verify its a boolean variable :) Title: Re: IF-THEN Post by: nyet on June 29, 2012, 07:55:23 AM I still dont understand the /X/Y notation...
eg / 10/100ms etc Title: Re: IF-THEN Post by: masterj on June 29, 2012, 08:25:52 AM Yea, since it appears to be a boolean operation, the value can only be a 0 or 1 to the variable. You can check this by searching for that variable and see how its used in other function, if its output is to a switch than this will verify its a boolean variable :) That value is just some random value I've chosen for this question. Let's say we get 1000 through that line. Now if...then condition is false. What value mslcorr_w will get? Or this may be more understandable: What happens if if...then condition isn't fulfilled? If there was if...then...else condition we would easily choose else, but if there's only if...then? Title: Re: IF-THEN Post by: masterj on June 29, 2012, 08:26:24 AM I still dont understand the /X/Y notation... eg / 10/100ms etc I think this is the time that ecu takes to test condition Title: Re: IF-THEN Post by: RaraK on June 29, 2012, 08:28:33 AM ^^yes
its a computing sequence, /sequence/process 10/100ms is 10th sequence in the 100ms computing time frame /1/ the first operation i guess for the frame?

Title: Re: IF-THEN Post by: RaraK on June 29, 2012, 10:17:53 AM i think id have to break down the whole function to understand this specific block better!
we know it means do this operation NOW if true, but is it only re setting the variable when the if block is true? and relies on last stored value if false? I am not so sure on this unfortunately, if you look at other blocks, its more clearcut how it works, this is goofy this specific example, maybe typo? |
