No lab files for C281x on C2000 teaching rom

I recently downloaded the C2000 Teaching Rom from TI's website. When attempting Module 3 for the C281x it states that I need to include a file called lab2.c for the project. This file doesn't appear to have been included with the zip file. Reading further modules I find that other lab exercises are based upon this c code. I was wondering if anyone has a copy of lab2.c for the C281x if they could send it to me or post the code online.

    for some reason the old 281x files didn't make it to the lastest CD-ROM. I have attached the solution files for all 281x chapters.

    Regards

    Hello,

    Thank you for your help,

    when I use the solution lf Lab2, I have those errors:

    (1) From the solutions zip file "lab2.zip" you should use the file "Lab2.c" and not the file "Lab2_solution_temp.c" as part of the project.

    (2) In File "Lab2.c" please delete the function, prototype and function call of function "SpeedUpRevA". This function was required for the first lot of samples in hte early days of the 2812. For all following silicon revisions this function can be removed.
