Hi Frederick,

Excellent post!! Thank you for sharing the sketch. This is fantastic, it builds on Peter's [mention:6e474abc33b64a82aa78c9813503c962:e9ed411860ed4f2ba0265705b8793d05] excellent documentation for the Fuel Tank board, and allows anyone to remotely check on the battery state of their IoT device!

This should definitely be bookmarked by many people. The Fuel Tank board is great for instantly creating a battery-powered WiFi solution with the CC3200 LaunchPad!!

(Just for confirmation, could you post the link to the header file that you used in the sketch? I know it is on the site somewhere, but I couldn't easily find it).

Nice post. The solution you are using involves connecting multiple pins of the launchpad itself.

Referring diagram at: http://energia.nu/wordpress/wp-content/uploads/2014/09/fueltankbppinmap.jpg

You could have connected the pins from J2(14&15) to J1(9& 10) which would have yielded the same result. I took a different path and simply 'cut' the traces to the J2 and soldered them to J1 instead. That way I free up two pins from the CC3200. The fuel booster works as is with the MSP430F5529 USB Lunchpad which has two I2C peripherals.

Additionally, If you need SPI in your design then the shorted pins will cause a conflict.

I will post on the cut and hack once I test out the code which I wrote in CCS. [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-cab64449-0a99-48ef-92e4-0599e0210c05/contentimage_5F00_1.png:16:16]

Very good post.

I hope to get back to my CC3200 and booster pack, so I plan to use this information.

Thanks
