change output type to pwm, adjust outs values 0 50 and change pwm frequency to 11hz.
@Pascal for this kind of things having pwm frequency configuration for each outputs would be better...

[Serveurperso]

La fréquence PWM est un hack pour le SoC et a des limitations strictes je crois pas qu'on puisse avoir des choix différents pour chaque PIN ou c'est en respectant le diviseur etc....

So I had a random thought from a storm that went by recently (and I promise this is related to vigibot stuff)

Sometime last year, a really close lightning bolt struck somewhere close enough to my house where it shook the whole thing and I heard my robots camera (supposedly) click a bit across the room.

I noticed my robot camera's night vision had stopped working around the same time and never connected the dots till now. Could these be related? Power cycling doesn't fix the camera

[Mike118]

I don't know if it is related... but if you are interesreted in knowing what part is faulty you can perform some tests. You can measure voltage on the photoresistor , and you can remove the photo resistor and hack it the way we hack the ir lights in order to control it with a pi gpio ...

Hello @ Tous !
petit question : je souhaite mettre en place une accélération et une décélération des moteurs principaux ( tests sur explorer@vigibot)
j'ai retrouvé cet article : https://www.robot-ma...n-servo-moteur/
mais l'arrêt progressif ne semble pas fonctionner ..
une idée ?

ca fonctionne !!!
dans commands8 , j'ai utilisé RAMPINIT pour la décélération
alors quel est la fonction de RAMPDOWN ?
il faut peut etre mettre à jour l'article avec les bon termes : RAMPUP, RAMPDOWN, RAMPINIT

i was driving it a little bit earlier, i suggest turning off the RAMPDOWN for the steering

[fredj21]

done !
but , i'm not use RAMPDOWN to enable speed reduction , i'm use RAMPINIT :
"RAMPUP": 1,
"RAMPDOWN": 0,
"RAMPINIT": 1,
now --> 0

[Mike118]

RAMPINIT c'est quand tu fais un retour à la position de neutre. Souvent tu veux la même valeur entre RAMPDOWN et RAMPINIT ... mais tu peux aussi décider d'être plus agressif en mode rampeinit si tu l'utilise plus comme un arrêt d'urgence... en gros rampe down se fait quand tu fais une décélération quelconque et rampe init se fait quand tu demandes spécifiquement de revenir au neutre... et ça overide le rampe down.

I think I already know the answer to this, but is Raspberry Pi Zero W capable of running vigimage at all (with or without camera) ?

[OdorousWo1f]

I believe it works
A zero 2 W or whatever the newer one is does work perfectly

[eidyn]

Oh nice! Will give it a try

[Mike118]

Yes raspberry pi zero works with camera but it is not as good as raspberry pi 3 or zero 2w.. Raspberry pi zero 2w and 3a+ works petfectly. ( of course 3b and 4 works perfectly too.)

[eidyn]

Ok, new platform. An RC crawler for really good torque from 3.7v
It will have a 3-wire micro servo for steering (controlled directly by RPi GPIO 12 and powered direct from the battery). The drive motor will be through a DRV8833 H-Bridge. Is this possible to be configured on Vigibot?

[eidyn]

Does anyone know the right configuration for the drive motor? It's a single DC motor through a DRV8833 H-Bridge, on GPIO pins 7 and 8

[eidyn]

Oh if GPIO 8 is reserved, I could use 9 and 10 instead?

[eidyn]

Ok, drive motor is working but because I replaced 'left wheels' and deleted 'right wheels', the mixing means that if I input a command to turn at the same time as full forward, the drive is reduced. I believe this needs fixed through the COMMANDS8/16 and GAINS8/16 but I have no idea how to fix this. Does anyone know?

[Mike118]

Hello, this may help you https://www.robot-ma...ds/#entry115626 and you can always check what was your initial config
@Eidyn if you need more help feel free to ask I will help you.

[eidyn]

Ah perfect, thank you so much!
