I am trying to run a 16bit conversion from the Delta Signal ADC to the DFB using DMA. I have set everything up as best I can but I can not get the Filter Interrupt to fire. I have confirmed the DMA transfer is working by monitoring the DMA nrq output. I get pulses at 2khz which is the speed I am running the ADC.
I then loaded the example Filter_ADC_VDAC project and it fires the interrupt fine.
I use the DMA wizard initially in my project any it wants me to use Filter_1_STAGEA_PTR for the destination of the DMA transfer.
If I change this to Filter_1_STAGEAH_PTR like in the example project the interrupt starts to work. However, when I read the filter
it looks like the output is just random data. I am feeding a constant 2V to the ADC.
Does anyone know why when I set the DMA destination to Filter_1_STAGEA_PTR the interrupt no longer works?
