#
# Things to think about
# 1) Should we set up an email account "PiFlyUser" to make it easier for users to share or report problems?
# 2) Should we set up a blog for sharing?
# 3) Should this script ask for a call sign during setup, install differently if none provided?
# 4) Should the shutdown button enable be delayed to the very end of the script? -- last thing enabled, all good now
# 5) Should the end of the script remind the user to set time zone, country, and so on? -- Done
# 6) Cleanup, remove source and unnecessary files? -- No, there is plenty of space.
# 7) Need to abort on failure
# 8) Need to check that there is enough space to do the whole install.
# 9) How to get pifm and nbfm to work on any NOOBS from 1.9.2 on?, They work on NOOBS 1.50, 1.70, 1.80, 1.90. rpitx works on 2.3.0
# 10) text2wave can't make a very long file with -F 48000 (needed for rpitx) for some reason, we now must use -F 6000 and SoX to change
# 11) Need to insert line into gpio-halt code to turn on Shutdown LED D7 on GPIO16 (pin 36) - done
# 12) Need to figure out how to use pi3-disable-bt.dtbo overlay so Pi Zero-W can be used with GPS. See: https://www.raspberrypi.org/documentation/configuration/uart.md
# 13) dtparam=i2c1_baudrate=400000 isn't working, i2c still running at 66,666Hz for i2cdetect and flips from 100kHz to and from 66kHz in Python.
# 14) Found set_config_var command here:http://iot.technoedu.com/forums/topic/raspicam-solved-how-can-i-enable-the-camera-without-using-raspi-config/  How does it work?
# 15) If halt request is low when Linux comes up (like when running from USB +5 on Pi and no battery connected with W5 closed), the shutdown command is never issued or recognized. The GPIO interrupt is edge sensitive, not level sensitive.
# 16) must look at RTC   https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=161133      and     https://www.raspberrypi.org/forums/viewtopic.php?f=37&t=59808
