AD-FMCOMMS1-EBZ input modification
Hi once again, I am attempting to connect a simple hardware module to produce a square wave output from the reference design into the DAC, and then view this output on the ADC using ChipScope. The...

Hi there! I am currently working on using the DMA together with an interrupt to exchange data with SPORT1 on a BF609. For some reason, the IRQ does not seem to occur with every XCNT=0 but rather...

Re: ADAU1761: Ground connection of earphone and microphone
Hi, Since you're using the main ground (GND) with your headphone jack instead of pin 21 (MONO-OUT), you no longer need the connection to pin 21. This pin serves as the Vcc/2 source for the...

Hi, Are you using the right combination of axi-clkgen core and driver? There is a v1 and a v2. Is it possible that you have a v2 in your design but a v1 configured in your devicetree? - Lars

The SED failure is because you have hard coded the values. It may be better to keep this check ON.Can you use the DDS enable signal to drive these values (BTW, why are you giving a DC offset)?

Yes...if DMA interrupt mode is set to ENUM_DMA_CFG_XCNT_INT, interrupt occurs when DMA_XCNT becomes zero. But since you are using Auto-buffer mode, eventhough interrupt occurs when X_CNT becomes zero,...

Re: AD623 gain ecg
Hello, The AD623's on-chip feedback path has about twice the resistance as that of the AD620, so you get more gain from the -623 with the same external resistor. The AD620 has a gain of...
