Other Parts Discussed in Thread: C2000WARE, TMDSHVMTRINSPIN
Hello,
I'm using "C2000Ware_MotorControl_SDK_2_01_00_00_setup" for my project and in that i'm using the "\ti\c2000\C2000Ware_MotorControl_SDK_2_01_00_00\solutions\tmdshvmtrinspin/is13_fwc_mtpa" folder as a reference.
I have created "TIMER0 ISR" and the "MAIN ISR" function which is already available is been interrupted by the ADC-C1 interrupt.
When i make the change in the "HAL_setupADCs(HAL_Handle handle)" function as per my requirement, then the "MAIN ISR" interrupt is not generated but the "TIMER0 ISR" is genrated.
But when i don't make any change in the "HAL_setupADCs(HAL_Handle handle)" then i able to generate both the interrupt "MAIN ISR and TIMER0 ISR".
For more information, PFD below.
==================================================================================================================
CODE WITH MY CHANGE: [In this only TIMER0 ISR is generated].
================================================================================================================
CODE WITH NO CHANGE: [BOTH ISR are generated].
