What you need

Reprogram your Arduino

After downloading and unzipping the upgrader applications you will need to reprogram your arduino to serve as a bootloader, follow the steps below.

  • Connect your Arduino directly to your PC (Connecting through USB hub may cause issues later)
  • Press windows key + r
  • Enter devmgmt.msc (this starts Device Manager)
  • Find Ports (COM & LPT)
  • Remeber this COM number (For example my Arduino is COM7)
  • Press windows key + r
  • Enter cmd (this starts Command Prompt)
  • Navigate to upgrader applications folder you just downloaded (for example I will download to my desktop)
  • After getting to the folder issue the command seen below

Using MindsensorsUpgrader tool

  • Disconnect your arduino from the PC
  • Attach the arduino to the EVShield
  • Navigate to the folder in which you saved the upgrader applications
  • run the program "mindsensorsupgrader.exe"
  • From the 'Device' menu in the mindsensorsupgrader, select menu item 'Select COM Port ...' and choose appropriate COM port.
  • From the 'Device' menu, select menu item 'Select Device type ...' and choose EvShield.
  • Then, from 'Device' menu, select menu item 'Open Firmware hex file ...', browse to the hex file, and open it.
  • Now from 'Device' menu, select menu item 'Upgrade Device ...'
  • Program will look for EVShield in bootload mode for about 10 seconds. Now within this time, on your EVShield, Press 'GO' and 'Reset' Buttons simultaneously, and let go the 'Reset' button while keeping the 'GO' button pressed, you can let go this button about 5 seconds later. (this step launches the EVShield in bootload mode).
