Arduino Uno controlling Regulator S7V8F5

Hi,

I am working on a project that involves interaction between the Arduino Uno and the Regulator S7V8F5. Does anyone have any suggestions on how I can ensure that the SHDN pin is held at logic 1 while the Arduino is being programmed? I would like to have the SHDN pin at logic 1 at all times expect when I want to set it low during the main body of the Arduino sketch i.e. in the loop function.

Is there a small and simple sketch that anyone can share to help me setup this sequence?

Thanks in advance.
David

Hello, David.

The SHDN pin on that regulator is connected to VIN through a pull-up resistor, so by default it is pulled high until driven low. I don’t think you should have to do anything special when you reprogram the Arduino.

Hi Jon,

Thanks alot for your reply. I got it both the hardware and software working last night. It works beautifully now.

Thanks
