First Steps

This page gives some basic information and describes how to get started with Code Composer Studio and TMS320F28335 Library

---

• A GPIO can only be configured for one module
• An overview of which GPIO can be configured for which module can be seen in the table below
• All possible GPIOs and ADC-Pins as Input-Parameter can be seen in the table below or in global_defines.h

1) Plan which modules you need in your program and which GPIOs you want to use for each module

2) Set up CCS Project and Import Library

4) Link Library to Project

3) Include global_defines.h and the header-files of the modules you want to use

4) Call setSystemControls() function

5) Call init-functions of the modules you want to use

• For available functions of each module see the description of respective module in Modules-Section
• In CCS main(): Type "init" and then press Ctrl+Space to see an overview of all init functions
