Need Phone App
|Status:||In Progress||Start date:||10 Mar 2019|
|Severity:||01 - Critical|
This is probably just a wrapper around the original dialog app from upstream, but might be more.
RM #700: Initial import of phone dialing app for Xeon phones. This app currently is just the UI and does not yet make calls.
RM #700: Fixed location of install files so app works with launcher. Switched to loading images early and only scaling once to improve performance on lightweight RPi Zero W.
RM #700: Added Exit button to allow leaving the app from the touchscreen interface.

Original PiPhone in python is here: git clone https://github.com/climberhunt/PiPhone.git
This is very short and could probably be written in C fairly easily. It's biggest change from my other apps is the AT modem usage. Modem information is available from Adafruit along with their tutorial which has pinouts and a link to the command manual, although the original didn't get nearly that involved.
I'll probably want to figure out how to make a phone call and send an sms.
Here is some code to send SMS messages. It's written in C for RPi so it's probably a reasonable start for phone calls too. It may be necessary to disable serial port use as configured by default by the bootloader, though I kinda doubt it in my case.
To get notified when a call or message comes in I need to poll on an interrupt on a GPIO pin. The Adafruit page has a link to the reference manual that says which pins to monitor. However, the sysfs interface is now deprecated and new code is supposed to use the new character device libgpiod library Example code is available.

The UI is written and appears to work okay on both the desktop and in Xeon. I can press numbers and special characters (# and *), delete characters and exit the app. The number is displayed at the top of the display.
Next step is to port the call commands from the original app. Then wire up the modem and give it a shot. Of course, I need to order a SIM card first. Probably ought to do that soon.
