1. Download and install Energia version 17 from energia.nu/download
2. Modify the cc3200.ld file and change the HEAP_SIZE value to 0x00007500.
Windows: this file is located in
C:\Program Files(x86)\energia-0101E0017\hardware\cc3200\cores\cc3200
Mac OS: right-click on the Energia application and select "show package contents"
then go to Contents/Resources/Java/hardware/cc3200/cores/cc3200
3. Additionally, the WiFiUdp.cpp source file must be modified (hardware\cc3200\libraries\Wifi), as its
function parsePacket() blocks during 10ms. The code has been modified to reduce this timeout to
1ms (change timeout.tv_usec = 1000 instead of 10000) to maintain a low latency and a 200Hz
update rate of the IMU streaming.
4. We also provide a pre-configured version of Energia 17 (Windows and MacOS) for an easier setup of
the environment; check out the root of the following GitHub repository:
github.com/BITalinoWorld/firmware-bitalino-riot
5. Get the SLFS library from github.com/Ircam-R-IoT/SLFS and copy it into Documents/Energia/libraries
6. Get the BITalino Energia library from github.com/Ircam-R-IoT/bitalino-energia-library and drop it into
Documents/Energia/libraries
7. Open the firmware.ino file with Energia and click the "Verify" button in the upper left corner. If it
compiles without errors, you're ready to upload your own code to the BITalino R-IoT board.
To upload your firmware the following steps are needed:
