LAUNCHXL-F280039C: Locating CPU Timer Definitions in TMS320F280039C MCU DriverLib

Part Number: LAUNCHXL-F280039C
Other Parts Discussed in Thread: TMS320F280039C, TMS320F28035, CONTROLSUITE, C2000WARE

I'm in the process of migrating code from the TMS320F28035 MCU to the newer TMS320F280039C MCU, both from Texas Instruments. In the original MCU, CPU Timer Definitions (e.g., 'mSec0_5", "mSec1", etc.- See Image below) based on a 60MHz system clock were present in the "PeripheralHeaderIncludes.h" file. However, in the newer MCU's corresponding file, "f28003x_device.h", these definitions are missing. I've also checked "f28003x_cputimer.h" with no luck. Can anyone guide me on where these CPU Timer Definitions might be defined in the TMS320F280039C MCU's DriverLib, or how I should approach defining these timer intervals for the new MCU?

"PeripheralHeaderIncludes.h" located in the directory "C:\ti\controlSUITE\development_kits\~SupportFiles\F2803x_headers" of controlSUITE
 


"f28003x_device.h" located in the directory "C:\ti\c2000\C2000Ware_4_03_00_00\device_support\f28003x\headers\include" in C2000Ware

    Hi,

    Those constants will be different based on the system frequency configured. I would recommend you try the driverlib example available in C2000ware\driverlib\f28003x\examples\timer_ex1_cputimers.c

    which calculates the required period value based on the sys clk configured.

    Regards,
