Re: CPLB miss after gpio-addr-flash access past 4M
Aaron, That was a good description for a change to uboot, but my u-boot is working perfectly without that change. Funny think though I tried it anyway because I thought the settings from uboot make it...

Hi Alex, I saw FTDI chip sends the address 0x4 and aduc7023 didn't ACK the address that is what I presumed wrong data on the data line. After that no activity on the bus and the error. Now if 0x80013...

Hi, For the clock input, it is a CMOS inverter, so the input current will be < +/-10uA. We do not recommend drawing more current than the 1.6mA specified as the test condition. Regards, David
View ArticleRe: AD5933: Can “Settling Time Cycles” register value be 0?
It would be great to see some official document(s) explaining the mechanism of why writing 0s into D8-D0 in registers 0x8A and 0x8B and sweeping causes erratic values in the output data registers....

zuzu, Several things. Note in the data sheet, the op amp is running on +16V so the output has enough swing to drive the MOSFET. The A301 data sheet http://www.tekscan.com/pdf/A301-force-sensor.pdf...

This noise picture you posted before shows a pattern which has a certain frequency, Can you tell me what it is? Do you have a scope you can use to measure it? Charly

Hello Christian, Sorry this question got lost in the shuffle. I imagine at this point you have worked out some suitable settings? The settings will depend a little on what the application is. For...

At some where you need to hack the HDL and wire your core outputs - definitely you can do this at the DDS signals. You will have to bring these signals all the way out of the core. You may leave the...

Hi Neil, When I wrote 3D I meant 3 axis data, not 0x3d... Actually, that problem appeared again in one of our units.The unit's ID is AD:1D:F2:02 and the 3 axis raw data isX: D7:00Y: FF:FEZ: 86:FF Does...
View ArticleRe: ADF4351 PLL lock time and step size
Using a 1 kHz channel spacing, will allow a PFD frequency of 4 MHz. That will allow you more freedom with your loop bandwidth - up to 400 kHz. I modified Ian's ADIsimPLL file for a 4 MHz PFD and 200...

OK, thank You. I inattentively read: “The ADCs, DACs, and serial port share a common sampling rate” (p.26). But, in “SERIAL DATA INPUT/OUTPUT PORTS” (p.42-43) nothing said about “R17.CONVSR[2:0]”, only...

You might try using beads instead of resistors. That will keep the DC path but kill the AC paths.
