"hai Randy.. i realy hope u can help me for IR( sharp gp2y) obstacle avoidance.. currently, im ussing arducopter 2.91 version. im now facing problem in reading IR sensor... under file, examples, AP_RangeFinder, AP_RangeFinder_test.... i just…"

"all solved now thanks. Found support on their forum.  the old fashion solution: just restart everything..."

"al, what's the problem? have you joined the visual micro forum for help?"

"is visualmicro working out ok for you, compiling the code, importing the sketch all right and uploading? I can't get it to work... "

"its ok. is there anyone else able to help me? i really need to sove my problems"

"Obertan,      I won't be able to help you with that version of the code I'm afraid.  It's a very old version and any investment of time I made in it would not contribute to the main code base which everyone…"

"do u still there? i was waiting this few days for ur help. u didnt answer. i really hope u get to help me in this project"

"sorry randy, i dont intend to use tat kind of huge code. im now using the code from this websites : http://diydrones.com/profiles/blogs/arduimu-quadcopter-part-iii Im just using the ir distance code for my sensor to work. now im going add on some…"

"You can find the latest ACM code in the download area here.   The instructions on how to load it onto the APM board using the arduino idea are here.   Do you have a flying quad?  Have you done programming before?  "

"where can i get the ap_rangefinder sketch? cause now im using thequadmini 1 29 rangefinder. im not using all the code in there. im just some codes tat need to use for my ir sensor. i just using the filter functions, position control. is there any…"

"hmm...well...I can try and talk you through it but I hope you have some programming experience and spend some time trying to understand the ACM code.   First thing you should do is try and get the AP_RangeFinder example sketch working for the…"

"i already reply but still no one help me mayb u can help me? pls...."

"Is this forum still working? I also trying to find out how to do obstacle avoidance. Im using IR sensors. I try out the rangefinder code. I got no luck.Do you guys know how to setup the motor? How to declare the motor?"

"Obertan,      In the AP_RangeFinder class you will find that it only provides a distance.  The code for obstacle avoidance should be in the main code.  There's a couple of other people who wanted to implement…"

"im using the code of range finder. i forget where i upload it cause its long time ago. im trying to edit it so that i get wat i wan for my project to work. I wan to know is it that not all code in range finder are used for obstacle avoidance? Only…"

"In stead of moving the motor directly, you should probably adjust the roll or pitch appropriately.  Then let the attitude control take care of firing the motors appropriately to achieve the required roll or pitch.   Jose did this…"
