Merci

C'est possible de mettre vigibot dans un train jouef Ho
?

[Mike118]

Oui et @Pierre l'a déjà fait il me semble.

[arkansar]

Yep je crois que c'est on lego train non ?

[pierre]

Yes je l'ai fais en faisant en sorte que ma pi commande mon esp32

Bonjour tlm
J'essaie de remettre en route un vieux robot
J'ai changer de wifi car déménagé.
Pouvez vous me dire dans quel fichier le configurer dans la sd svp ?

[Mike118]

C'est dans wpa-supplicant.conf mais ce fichier est automatiquement retiré de la carte sd pour des raison de sécurité après démarrage du pi. Tu peux refaire un fichier en regardant sur internet. C'est du standard " raspberry pi " ça n'est pas quelque chose de propre à Vigibot

[arkansar]

Mais c'est pas toi qui avait un gros 4x4 robot

[pierre]

Si c'est moi

It seems the IP2312 is picky regarding input voltage. Datasheets states a current gradient depending on Vin, with
Vin: 4.5V = 0A charging and
Vin: 5V = 2.1A charging and
(Vin: 5.5V = 3A charging.(?))

The problem is, with the robot running and using ca 1.5A, the Vin is low enough that the IP2312 only charges with 0 - 0.3 A.

I had no other idea than to build a converter, with a PD decoy requesting 9V from the PD2.0 charger then a step-down to
first ca 5.5V = 3A charging, but the magnetic plug gets too hot.
then ca 5.3V = about 0.7 A charging, together with the robot's usage of 1.5A, results in a total Current of 2.2A, which gets the magnetic plug somewhat hot still....

I wish there was a better way, and think using a higher charge voltage like the geekworm v3 (9V or 12V) would be better. @Garfield2142

[garfield2142]

On the bottom of the new beta vigiups board, there is a solder bridge for Vusb, should I try bridging it to 9v or 12v?

[firened]

Is this to set the requested USB voltage @Mike118 ? If so then, that's dope AF.

"CH224K Low-cost USB-PD Sink Controller" <https://components10...-controller-ic>

Must be it!
Then yeah, probably 12V, that should fix the charge speed and magnetic plug temperature

[garfield2142]

Alright, I'll revive Pluto, then set Panther's vusb to 12v and see what happens!

[Mike118]

You can checked BQ25792RQMR datasheet.
For the new charger and yes it is a CH224A
@Garfield2142 this is the issue when charging :

@Garfield2142 is your voltage meter script already running?

[garfield2142]

No, I didn't make one yet

[firened]

Did it crash this way before we added the current bar?

[Mike118]

This is not linked with adding current bar. There is this i2c error when charging and The charger is connected on the i2c bus.
