Re: How to port map to DMA interface?
It is a FIFO- (search for FIFO interface) dac_drd - use it to increment your FIFO read pointer.dac_ddata - pass FIFO output to this input (latency is tolerated)dac_dvalid - 1'b0 is good...

Hey there, I've written a code to communicate with a RTC via I2C but I can't seem to get it working. Using the osciloscope I can see that the CLK signal only outputs 2 bits... When I changed the slave...

Yes - and I forgot that you are interested in Altera. Since Vivado allows us to get out of the "EDK structure", the same library will be used in Altera carriers also (hopefully both can get along well).

After debugging it looks like the power rail for the xcvr chip (ad9361)on the eval board is not getting the power good signal (PG-FMC) from the ZC702 board (should be asserted highand it’s not). As a...

Hi, Can you check whether your ZC702 is affected by this AR #51438. Check if DS13 and DS24 light up. If they don't you need to reprogram the power supplies on your ZC702. - Lars

Re: AD1937 input into ADAU1442?
Hi Dave, Thats not good news i don't see anyway i can change the clock inputs on the finished PCB without re designing and having new boards made. Would it be better to make the 1937 run in slave mode?...
