I have a question about using PDB with ADCs on a Kinetis K60.
My system is as follows:
ADC0, A-channel must be converted every 1 ms
ADC1, A-channel must be converted every 10 ms
ADC1, B-channel must be converted every 10 ms
So I initialized PDB for running with 1 ms and enable ADC1 pre-trigger in every 10th PDB interrupt service routine..
It seems to work, but I don't know if this is a safe way to do that. My code for the pdb-isr is as following:
void pdb_isr( void )
PDB0_SC &= ~PDB_SC_PDBIF_MASK;
static intx cntPDB = 0;
if( ++cntPDB == 10 )
cntPDB = 0;
PDB0_CH1C1 = PDB_C1_EN(0x01) | PDB_C1_TOS(0x01) | PDB_C1_EN(0x02) | PDB_C1_TOS(0x02);
PDB0_CH1C1 = 0;
}// end of HwADC_PDBISR()
