Pierre's 170W in 1600W out Looped Very impressive Build continued & moderated

All,

To maybe help sort out the the confusion, the 2560 board I shipped to Luc uses An Atmel Mega16U2 as compared to the original Arduino AtMega8u2 for USB communications.

Regards,

Actually, there is a reset button on the board, see attached image. Try pushing that and then immediately after uploading the sketch, or the other way around, start the sketch upload, then press the reset button.

Good idea Pmgr and it worked. So now I have a successful high frequency upload. So before trying it again I'm going to do some (in out) power tests at this frequency.
When you get the chance can you please add the potentiometer function to the program you modified for me so I can have that available if my next upload is also successful.
The below video contains some scope shoots of the device operating.
Thanks for everyones help

Fr. Bonne idée Pmgr et ça marché. Alors maintenant, j'ai un téléchargement à haute fréquence réussie. Donc, avant d'essayer à nouveau, je vais faire des tests (in out) de puissance à cette fréquence.
Quand vous en avez l'opportunité, veuillez ajouter la fonction potentiomètre au programme que vous avez modifié pour que je puisse l'avoir si mon prochain téléchargement réussit.
La vidéo ci-dessous contient quelques prises d'oscilloscope de l'appareil en fonctionnement.
Merci pour l'aide de tout le monde

Use linux, not need drivers.


Sorry, I see it's fixed now

Attached is the sketch with the potentiometer added back in (other line with x=5 commented out).

Hi Luc,

Impressive build.

I rewrote an alternative version to be more adaptive, it compiled fine but haven't tested on hardware. The only line you have to change is:

const int msDelay = 0;

When set to 0 it will take the delay value from the attached potentiometer.
When set to anything other than zero it will use that for the delay in milliseconds.

I noticed the L298n can switch down to the microseconds but doesn't like long delays >100ms maybe it's the board or my setup but it slopes off quickly. So delay() could be replaced with delayMicroseconds() later on.
