[FAQ] AM13E23019: How to add FastRTS math functions to a project

Part Number: AM13E23019
Other Parts Discussed in Thread: MATHLIB, SYSCONFIG

Hi,

I imported the adc_mcpwm_trigger project and tried to use the FastRTS (TMU) functions in this project by including the "fastrts_tmu.h" file as instructed in the document "README_AM13E230X.md" in the mathlib/fastrts library folder, but it didn't work;

What is the procedure for including the FastRTS library in a project?

Hi Ari,

Please refer to the project :

am13e2x_sdk/examples/mathlib/fastrts

Also what do you mean by it did not work, do you get build issues or teh results are not as per expected.

Hi Nilabh Anand,

I've already checked this project. My problem is how to give other projects access to TMU in the same way this one does. Is it a matter of configuration in Sysconfig?

Hi Ari,

The sysconfig does not have changes for TMU. It is direct API calls made via the correct library linked to the project. Make sure your project has the correct libs linked (you can compare it with the SDK fastrts project)

The TMU Functions get linked to the CMSISDSP library.

Shaunak

Hi Shaunak,

I've already figured it out, you just need to include these two include paths in the compiler options:

${COM_TI_AM13E230X_SDK_INSTALL_DIR}/source/mathlib/fastrts
${COM_TI_AM13E230X_SDK_INSTALL_DIR}/source/cmsis/DSP/Include

Thanks,

Ari
