So you’ve got your tiva launchpad and are now willing to start experiment with it right?
Although Ti provides clear documentation on how to get started using the launchpad, there are still some ambiguities which needs to be addressed. I’m writing this post to make it clear for how to start using the launchpad and how to upload our first led blinking code into it. We’re using the tiva c series launchpad with Texas Instruments TM4c123GH6PM Cortex M4 microcontroller on it. This is also called as TM4C123GXL. This is name of the launchpad kit
TM4C Tiva C Launchpad
This is a very simple and powerful tool to use. The detailed instructions on how to get started are given on the getting started document listed here
For Our Experimentation, am just noting down important steps which are needed before we start experimenting with this launchpad. This is for current and future reference
Download the Code Composer Studio from here CCSTUDIO IDE, configuration, compiler or debugger | TI.com
Download the Tiva C Series SDK from here SW-TM4C Software development kit (SDK) | TI.com
Extract the SDK and keep in a simple location on computer, like C :\\ ti\ SDK_FOLDER
Install Code Composer Studio
Open Code Composer Studio
Create a new project
Select the device TM4C123GH6PM
Select the Connection as Stellaris ICD
Create a blank project with main.c
Once Project is created, go to project properties
Go to Build –> Arm Compiler –> Include Options
Here add the path to the folder where the Tiva SDK is kept on computer
Next, goto Build –> Arm Linker –> File Search Path –> and here, add the driverlib.lib file address from tiva SDK folder, on my system that address is like this, C:\ti\TivaWare_C_Series-2.2.0.295\driverlib\ccs\Debug\driverlib.lib
Once these things are done, click apply and close and the code should build now.
Again for reference, here’s how the Properties –> Build –> Arm Compiler –> Include Options should look like
And the Options in Properties –> Build –> Arm Linker –> File Search Path should look like this
Once these options are set, the code will build and generate an .out file.
If you want to generate the .bin file to download using LM Flash Programmer, then there’s just one additional step.
Goto Project Properties
Build Options –> There are various tabs, selectthe tab “STEPS”
in this tab, there’s a window called “Post-Build-Steps”
This window should be by-default empty
Paste this line as it is here
“${CCE_INSTALL_ROOT}/utils/tiobj2bin/tiobj2bin” “${BuildArtifactFileName}” “${BuildArtifactFileBaseName}.bin” “${CG_TOOL_ROOT}/bin/armofd” “${CG_TOOL_ROOT}/bin/armhex” “${CCE_INSTALL_ROOT}/utils/tiobj2bin/mkhex4bin”
Click Apply and Close
Now When you build the project, a bin file will also generate which can be used to download code in any IC using Programmer
After these options, the screen should look like this
Hope it clears all your doubts. For any issues feel free to submit a comment here
