In a device I am using, I see the following in the description...
"At start-up, the module requires an ON_OFF pulse sent from the host. A second pulse sent from the host will re-enter hibernate mode. The ON_OFF pulse needs to be the rising edge of a low to high pulse, this needs to be longer than 90us."
I am not clear on what the requirement is. For time being, I have the ON_OFF line being tied to the application of power. When I switch on, this line will transition from a low to a high... and stay high...probably very quickly.
I do not believe what I am doing is correct. I am trying to understand the interpretation of what is asked and I think it is really the following..
Does the above mean..(High voltage is 1.8V). "When you apply power and switch on, make the transition from 0 volts to 1.8 volts take at least 90us?"
This is of course without regard for if the line ever goes low again.
If that is so, could I accomplish the above with an RC circuit on the power line?
Here is a link to the data sheet.. https://antenova.com/wp-content/uploads/2015/11/M10478-A1_12MD-0050-3-PS.pdf
What I quoted is contained in that link. There are other aspects of this chip which I don't quite fully understand from he datasheet. Yet, the fact that it is not running properly is probably related to the On pulse and what I initially setup.
