      Hello ,

      I run a Lopy + deep sleep shield on my own board that has a power supply of 5V with a low rising time on VDD_L
      in this case, the Deep sleep shield never start and VDD_H is never activated hence the LOPY never start.
      I am assuming the PIC on the deep shield never POR because of this slow rising VDD_L .

      I know there are ways in the PIC to take care of this ( PWRT can be used to extend the start-up period until all device operation conditions have been met), but without the PIC source code, there is no way for me to change that.
      My Question , Can the PIC source code be available that I can enhance it ?
      best
