large values in ​​prox.horizontal

[mkany]

Hello, my Thymio is using the _fwversion 7.0. Now, when I program prox.horizontal with the VPL, then values ​​in the range 150 to 500 implemented automatically, but prox.horizontal [i] returns, values ​​between 1200 and 5,000. maybe, missing here a division by 10? prox.ground values are ok.

Hello, I'm not sure what your problem is; but here is some information:

• prox.horizontal is 0 when no obstacle is detected, and ranges from ~1000 (far) to ~4500 or 5000 (close) when something is detected
• prox.ground.delta is not implemented in the same way. It ranges from 0 (nothing) to a few hundreds when something is close.
• prox.ground.delta and prox.horizontal are updated automatically depending on what the robot senses; you can not program the values they should take.

Does this help you? Do you have another problem? If so, can you provide a screenshot and some more explanations of you problem?

Then we have a problem, meaning that firmware v7 breaks VPL. Indeed, VPl tests < 400 for close and > 500 for far.

V7 normalise the minimum value of the sensors. Before a normal sensor was between 800-4500 and the range for the min was 700-1200. They was some tricky sensor that have the minimum that was 3000 and the max 5500 Now in V7 the range will be more 1000-4500 and most min value will be between 1000-1200

Yes V7 change the min value but do not break the VPL because before it was the same. I never see sensors between 400 and 500. I will suggest to use this value <1200 and >1600

sorry, I closed the issue, wrong button. thank you for the help and information, I think it's no problem for me to correct values in text/VPL. I'm waiting for aseba 1.3.2 ;)
