Dash Firmware and Arduino Integration Updates

Hardware (and firmware) Dash
1

Hi everyone, we’ll use this thread as a changelog for updates to the Dash system firmware and to the Arduino integration.

Today we released version 0.7.1 of the Arduino integration. The IDE should give you the option to upgrade automatically. Changes include:

  • Fixes to printing floating point numbers
  • New sleep functions for switching the user module into a lower power state
  • Fix some USB bugs
  • Fix Arduino build warnings
  • Functions to query battery percentages
  • I2C master mode
  • Distinguish better between USB and OTA in the programmer menu

We also released version 0.6.1 of the Dash updater utility. This is installed as part of the Arduino integration and will also be available on our website for direct download tomorrow. Changes include:

  • File open dialog now works correctly on OSX
  • Cleaned up some error messages and made some more helpful

Hope you guys like all this. Stay tuned for more updates soon.

Today we released version 0.7.2 of the Arduino integration. Changes include:

  • Use indexed pins for Arduino compatibility
  • Large buffers for serial USB
  • Fix to snooze()
  • Changed IO interrupts to use attachInterrupt()

We also released version 0.6.2 of the Dash updater utility. One fix in it this time:

  • Fix an occasional crash when doing a USB update on OSX
4

Today we released version 0.9 of the Arduino integration. Lots of exciting changes in this one:

  • Add timed deep sleep functions
  • Fix some pin naming issues
  • Implement analogWrite()
  • Fix issues in flushing serialUSB
  • Add some SPI compatibility functions
  • Add digitalPinToInterrupt function for compatibility
  • Fixes to deep sleep
  • Make micros() more accurate
  • Change USB vendor id to allow for the use of a signed driver (You’ll need to recompile and reupload your user program for the signed driver to work.)

We also released version 0.7 of the dash updater utility. This contains some significant changes as well:

  • When you perform a user program update, the utility will check to see if you have the latest bootloader and system firmware and offer you the option to download them and update the device (Updating the bootloader is strongly recommended as this will switch the Dash over to our reserved PID and VID values and allow for the use of our signed driver.)
  • Improvements to our build process on Windows

Today we released version 0.7.1 of the Dash Updater utility. Fixes:

  • Fixed issues with running on Windows 7
  • Put a cool hologram icon on the binary (just shows up on Windows at the moment)

Right now, it’s available at https://hologram.io/docs/hardware/hologram-dash/downloads/ and we’ll be bundling it with the next version of the Arduino integration.

Today we released version 0.9.1 of the Arduino Integration. Your Arduino IDE should start bugging you to upgrade soon.
Fixes:

  • Battery management functions
  • IDE now uses Dash Updater 0.7.1 by default so Win7 users should no longer have issues
  • Slave mode driver for I2C
  • Add user setting of ADC sample cycles
  • Add Serial Number function to Dash Class
7

Today we released version 0.9.7 of the Dash system firmware:

Fixes:

  • First message bug is finally fixed!
  • Connection will be much more reliable and should automatically reconnect if it goes down.
  • Fewer modem resets
8

Today we released version 0.7.2 of the Dash Updater and version 0.9.2 of the Arduino IDE integration.

Changes:

  • Battery fuel gauge access is now split into a separate FuelGauge class outside of the Dash class. Docs will be updated very soon to reflect this.
  • Dash.begin() is now called automatically.
  • Battery charger is now cycled automatically though it can be manually controlled if needed.
  • Dash Updater will show the success message in the Arduino console instead of popping up a dialog box. Error messages will still pop up.
  • Dash updater now can be run with --text-mode for a full CLI experience.
  • Dash updater supports organizations so you can do an OTA update on a device in any organization that you belong to
  • Menu items to select Dash-related things in Arduino IDE are now named with hologram.io instead of konekt.io

Documentation about the above change to the battery monitor has been updated. The gist is that instead of calling Dash.batteryMillivolts() (or another battery function) call Charger.batteryMillivolts() instead.

See https://hologram.io/docs/reference/dash/api#battery-charger for more information.

10

Today we released version 0.9.8 of the Dash system firmware and version 0.10.0 of the Dash Arduino Integration. This is a really exciting update that revamps our entire IPC system so that we can add cool features like:

  • Cell signal strength
  • Smarter SMS handling with callback functions
  • Topics on cloud messages
  • Lots more stuff

Today we released version 0.9.9 of the Dash system firmware and version 0.10.1 of the Dash Arduino Integration. Lots of cool stuff in here:

  • Receive and respond to inbound data packets
  • Functions for getting cellular operator and ICCID
  • Renamed tags to topics in function names (old functions still exist, but are deprecated)

We also released version 0.7.3 of the Dash updater. This is available on the download page and is included in 0.10.1 of the Arduino integration. Changes:

  • Fix issue with doing OTA update to a device on an organization
  • Update some internal libraries that seems to fix some issues on older versions of Windows.
12
