Additions:
https://thepihut.com/blogs/raspberry-pi-tutorials/17209332-adding-a-real-time-clock-to-your-raspberry-pi
i2c device so when plugged in - run this to see if it is there
sudo i2cdetect -y 1
set up ntp to set the RTC (I did that with network and GPS time)
Run ##sudo hwclock -w## to write the system time to the RTC board.
then will need to add the RTC kernel module to the file /etc/modules so it is loaded when the Pi boots.
##sudo nano /etc/modules##
add rtc-ds1307 at the end

Revision [2634]

Edited on 2016-12-12 22:32:02 by ZorrUno [usb relay]
Additions:
**Possible fix needed?**
##Note if you're using the Raspbian Jessie or later release
you'll need to disable a systemd (system management daemons) service that gpsd installs. This service has systemd listen on a local socket and run gpsd when clients connect to it, however it will also interfere with other gpsd instances that are manually run (like in this guide). You will need to disable the gpsd systemd service by running the following commands:
sudo systemctl stop gpsd.socket
sudo systemctl disable gpsd.socket
Should you ever want to enable the default gpsd systemd service you can run these commands to restore it (but remember the rest of the steps in this guide won't work):##

Revision [2633]

Edited on 2016-12-12 22:14:40 by ZorrUno [gps and gps ntp time]
Additions:
- Plugged in the GPS mouse

- installed ntp and got time set with GPS

Revision [2632]

Edited on 2016-12-12 22:13:18 by ZorrUno [gps and gps ntp time]
Additions:
Next you need to edit the file: /etc/ntp.conf and add a few lines to it defining the GPS. This can be either before or after the existing lines beginning with server:
# gps ntp
server 127.127.28.0 minpoll 4
fudge 127.127.28.0 time1 0.183 refid NMEA
server 127.127.28.1 minpoll 4 prefer
fudge 127.127.28.1 refid PPS
then restart ntp
##pi@raspberrypi:~$ sudo service ntp restart##

Revision [2631]

Edited on 2016-12-12 22:09:11 by ZorrUno [ntp time with gps]
Additions:
then modify ntp to set system time based on ntp

Revision [2624]

Edited on 2016-12-12 19:22:58 by ZorrUno [GPS Setup]
Additions:
- Got i/o pins working for hold and ACC active
- Moved GPIO pins as interfered with placing the RTC
- Got the RTC working
- Scripted the first part of bootup to set the GPIO
++Used a 4 pin floppy disk connector on physical pins 7,9,11,13 which equates to IO4,GND,IO17,IO27.
The connector has fly leads of yellow (io4), black (gnd), black (IO17), red (IO27). The black was useful as a gnd for first testing IO but both black lead was then snipped.++
Changed to individual pins - GPIO 27 and 17
**GPIO Port 17 for HOLD** (setting as 1 sets GPIO 17 to 3.3v)
echo 17 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio17/direction
echo 1 > /sys/class/gpio/gpio17/value##
notes, this is obviously volatile... on reboot GPIO17 ++is high++ appears high, but is actually floating. It appears to drop low when direction is set to 'out'
