Procedure
1.
Create a new folder on desktop location.
2.
Open ccstudio on desktop.
3.
Browse the workspace location
Click on browseàdesktopàselect created folderàok button.
4.
ccs wizard is opened
5. Click on projectànew ccs projectàtarget [select Tiva c
series] select the micro controller “Tiva MC4123GH6PM” then connection as “Stellaris in-circuit debug interface”.
Then type the project name and click the finish button in new CCS project.
6.
Open restore on the left side and
enter the program and click save
button.
7.
Click the GPIO in project explorer.
8.Click
the GPIO project and right click then go to properties and select the include
options then click add button and select browse.
9.
Unfold the computer, open the local disk (c:) to select ‘ti’ and
tivaware_c_series_2.1.2.111 after selecting click the ok button.
10.
During the compilation process to import peripheral library files process,
select the ok button and click on the ok button.
11.
In order to add files to project select the project and click on the add files.
Now by giving double click select the following,
local disc (c:)àtiàTivaware_c_series_2.1.2.111àdriverlibàccsàdebug.
12.
After debug, select & open the driverlib.lib and then click on the ok
button and build the program.
13. Connect the switch in debug mode to
Tiva series launch pad and connect the USB output then debug the program
into launch pad and click resume button and observe the output.
