Wake up from the sleep?
Hi.
I know that we can block the device from powersave by writing to /sys/power/wake_lock, but can we do the opposite and force it to sleep with a timer set to wake up the device after some period of time? The main idea is to write a script that wakes up the device periodically to download some data and, possibly, display it on the screen. This way, the device could be used to display agenda in a conference room for much longer than with the sleep disabled. What do you think? |

Thinking about it in psuedo code way. I'd do this
Create a sh script Create a infinite loop based on a time interval (I don't think we can use systemDTimers or CRON) In the loop get your data that you want In the loop call one of the inkview apis that wake the device maybe OpenScreen() from this link https://github.com/blchinezu/pocketb...lude/inkview.h Display with Dialogshow Have an option to exit the script in the DialogShow So something like For( time interval) do GetData() Call Openscreen() ShowDialog() If DialogReponse == exit Exit End loop Exit Not sure how this would effect battery with an infinite loop. If someone knows how to set timers up please reply! I'd like to know as well |

Hmm, I am not quite sure how this could wake up a device after some time of sleep.
Anyhow, I've looked into that header you linked and there is a method called GoSleep(int ms, int deep). Maybe that could work, something like: while True: GetData() GoSleep(300 * 1000, 1) # Deep sleep for 5 minutes Do you know if these methods can be called directly from the shell? |

The dialog one can for sure. Take a look here at a small shell script I created to update KoReader book progress to pocketbook library https://github.com/jjrrw174/PocketBo...ith-PB-Library
