Part Number: LAUNCHXL-F28379D
Other Parts Discussed in Thread: TMDXIDDK379D, C2000WARE

Tool/software: Code Composer Studio

I want to evaluate F28379D's function below with LAUCH PAD(LAUNCHXL-F28379D).

-According to the datasheet, we understand that the conversion time of a 16-bit ADC is 915ns.
Is there any sample programs to measure this time?

-According to following URL, I understand that FOC processing period is 460ns.
Is there any sample programs to measure this time?

Would you tell me which sample program in C2000 ware is the best sample program above purpose?

Hi Naoki,

If you want to observe the ADC sampling time, you can use the adc_soc_continuous example. Drive the ADC pin through a large series resistor (say 10kohms) and observe the sampling kick-back with an oscilloscope directly on the ADC pin.

Please download the MotorControl software development kit (SDK) as the following link.

C2000WARE-MOTORCONTROL-SDK: http://www.ti.com/tool/C2000WARE-MOTORCONTROL-SDK

You might refer to the "fcl_f2837x_tmdxiddk" example project in the folder below, which uses getFCLTime() to cacculate the FCL time as you metioned above.
