v1.13

Version 1.13 is an Alpha release. This is a snapshot of current development as we are now freezing the RPi 2040 development. Now that Adafruit has started shipping the Feather M4 Express again, we shelved the rp2040 PCB project.

New: Added a bar graph history of satellite reception for the last 8 minutes.

Fixed: Task scheduling is more reliable, although a lockup condition is still possible after several days of continuous operation.

v1.12-beta

Version 1.12 is a Beta release containing significant changes. Please report any problems, thank you.
New:

• If GPS satellite signal is lost, make an audible announcement every 5 minutes. This is often enough to tell the driver without distracting them too much.
• Re-wrote entire breadcrumb trail and 'dump kml' function.
• Internal history now keeps track of more information: speed, direction, altitude, and number of satellites. All these are available in 'dump kml' and can be displayed in Google Earth and other KML-compatible programs.
• Breadcrumb trail now records are "power up" and "first valid time from GPS receiver". This will help diagnose situations where GPS reception is spotty.
• Automatically records GPS position every 10 minutes to keep track of being parked in one spot for awhile.
• Animated logo on opening screen.

Fixed:

• The main display screen no longer bogs down when the breadcrumb trail has more than 1,500 items. This would also cause slow GPS sync and loss of GPS signal because it failed to poll the GPS chip often enough.

This is a Beta test version 1.12 and significant changes have been made. Please report problems to Barry (griduino@gmail.com). We suggest you bring 'griduino_v106.uf2' on critical missions, the previous reliable version, in case you want to revert back from this beta version.

v1.10

New: More support for NMEATime2

v1.09-beta

What's Changed in 1.09
Fixed:

• Fixed hang condition in startup on Hints screen
• Rewritten save/restore of GPS bread crumb trail

Changed:

• Increased the GPS breadcrumb trail from 750 miles to 1500 miles
• Added NMEATime2 compatibility. Now you can continuously update your computer's data and time from Griduino.

This is a Beta test version 1.09 and significant changes have been made. Please report problems to Barry (griduino@gmail.com). We suggest you bring 'griduino_v106.uf2' on your travels, the previous reliable version, in case you want to revert back from this beta version.

v1.08

What's Changed in 1.08
Fixed:

• Fixed a hang condition in startup on the Hints screen
• Fixed the volume control screen
• Improved the touchscreen calibration
• Updated expired countdown events

Changed:

• Reduced the GPS breadcrumb trail from 800 miles to 750 miles
• Added description of file handling to Programming.md
• Updated example programs to refactor the pin definitions into 'hardware.h'

This version is recommended for all users.

v1.07

What's Changed in 1.07

• Added terminal session commands. Now you can open a terminal session to Griduino, such as the Serial Monitor in the Arduino IDE and send commands. This supports debugging, file management, and future Griduino desktop/laptop programs.
• Increased the breadcrumb trail from 400 miles to 800 miles.
• Updated the countdown events for the 2022 calendar.
