Other Parts Discussed in Thread: C2000WARE
Hello,
I have tried one exercise where ADCA and EPWM1 initialize and run under core 1 and ADCC and EPWM2 initialize under Core 2 code.
I have provide ownership of ADCC and EPWM2 to CPU2 in core 1 code (in main). The ADCA on core 1 working fine but ADC on core 2 is not working even during debug I observed adc control register value not changing and interrupt also not coming.
Here is the code for core 2.
