Hi,
I have the follwing challange:
I have 3 ADC's (16 Bit parallel bus interface AD7643) connected to the EMIFA-interface of my OMAP L138 processor. I'm using the SoM from Critical Link MityDsp L138 which has already an 128 MB mDDR connected to the EMIFB. Now, I want to sample circular, every 1 us, each ADC and transfer this datas to the mDDR. The CPU, C6748, shall get after a certain time period (round about 100 us) all the sampled datas to do some filtering. One input line to the DSP is signaling that all 3 ADCs are finished with the actual conversion. The memory adresses for the ADC's are these:
ADC1: 0x6600 0001
ADC2: 0x6600 0004
ADC3: 0x6600 0010
Is there a way to configure the EDMA3 controller on my C6748 to transfer on every signal on the connected line, ADC finish, the Datas from the adresses above to a location in mDDR? If yes, can anybody help me to understand how?
Thanks a lot for all comments!!
