Please use an init script during connection to specify the desired pwm when connection. That is proper programming technique.

what about Arrow Keys ? when they're enabled , if you move the pwm sliders, Arrow Keys work no more, and you have to click again to restore them. It's normal ?

Ezrobot is not responsible for the behaviors of the Microsoft Windows operating system. The arrow keys work on most computer, and I cannot be certain of the reason they don't work on yours.

Please let me know what script I should write and where, to have Pwm signals at the pins when I start my project. I have no signal at the pins, unless I move sliders in some way.

You bet! There are detailed instructions to specify the Speed (PWM) parameter for initialization on the HBridge PWM manual page, located here: https://synthiam.com/Tutorials/Help.aspx?id=192

Select that link, or press the ? (question mark) next to the X (close) on the HBridge control to view the manual page. Each control has it's own manual page by pressing the ? (question mark).

The section in the manual that is relevant to your question is titled "Initialization Code"

Let me know if you have any further questions regarding initializing the PWM when the EZ-B connects

Sorry, DJ. No more about this. I'm exploring everything in the ez world. I need a lot of information. I promise I'll ask for information only if I don't find in tutorials what I'm looking for...

It's okay Do not worry - you're doing great! Let me know if my response was useful.

i t was useful. Now it works. I'm new in ez world, and tutorials aren't always sufficiently detailed for me. I come from a different environment (Basic and/or assembler in embedded MCUs) . I haven't yet an EZ mind. For example, I go mad seeing I have to be careful even writing simple code, because it might flood the system ,or make it very slow.
