Hi @Stanko The written address and data should be what it was specified. It returns error or nak index and the read data.

Hi @Stanko You are getting NAK on the first word, at the address. Make sure the address is correct, is 8 bit format, see the examples.

Hi @Shalin See the following example where 3 words of 16bit are set on TX and 4 words received on RX dwfvi.zip Captured with an AD3: I have LV 2022 installed so I can't open your project.

Hi @CWS For warranty and replacement contact the support.digilent @ ni.com specifying the Date of Purchase, Seller and Purchase Order/ Web order Number.

Hi @BobA I can't find any connector with key but the thickness and length of 0.2/0.62 in should fit, in the Digital Discovery 2x6 hole of 0.26/0.65 in https://www.digikey.com/short/wph8rbh1

Hi @Raj62 The Digital Discovery has 16 digital IOs and 24 input only lines, system frequency adjustable between 50-100(125MHz), Logic Analyzer up to 8bit@800MHz, 256MiB of DDR RAM. The Pattern Generator with 32Ki samples/channel and play mode, for regenerating long captures or custom pattern, is available from Logic Analyzer. If you also need analog capabilities, inspect signals analog/digital signals or generate analog waveforms, I recommend Analog Discovery 3. The AD3 has 16 digital IOs, system frequency adjustable between 50-125MHz. The Pattern Generator with up to 32Ki samples/channel. The software and device features can be explored in demo mode. The pattern can be drawn manually, pasted in the table, imported from text/csv file, generated from the Script tool, or device controlled by custom app/script. If you want to generate 200 pulses with let say 10% duty resolution (10bit/pulse), this requires only 2000 fixed rate pattern bits.

Hi @Eleni You could use "Min/Max" sampling mode.

Hi @A.Chuck This could be caused by a high USB voltage, such as a faulty hub supply. Be careful with these, as they can damage other devices.

Hi @A.Chuck The USB controller generates its 3.3, 1.8... supplies. Do you know how got this board damaged ? other ICs could be damaged as well.

Hi @CWS See the following post:

Hi @Stanko The Digital Discovery has 16 DIOs and 24 DINs. Only the DIOs can be used for protocols. These are labels as DIO24-39 and in programming used with 0 base indexing, 0=DIO24, 1=DIO25...

Hi @BobA See a search filter for 2x6 2.54mm https://www.digikey.com/short/mrffpp30 The pin lengths are about 6mm, so an 'insulation height' of about 8-14 should be used... depending on the connector type. Also make sure the header is not to thick to fit in the case cutout.

Hi @lombster Add and modify LogThr and HighThr measurements

Hi @A.Chuck See the following post:

Hi @A.Chuck The USB controller is not reprogrammable. The receptacle may be broken or the controller damaged.

Hi @pfm

Hi @dfullerton6 You could try downloading it with another computer or phone then transfer it to the Mac.

Hi @A.Chuck This error can be caused by USB line contact problem or damaged USB controller. Try using the original USB cable or other cables you have at hand. If this does not help, the USB port or the controller may be damaged.

Hi @pfm Thanks for the observation, I will fix it soon.

Hi @dfullerton6 Probably a browser or internet connection problem, the download may be interrupted. The file name also looks weird. It downloads correctly for me. You can try to download the latest dmg from here or use another browser or computer to download.

Hi @cetapc Try "Disable device" on the COM port opened for AD2, instead of restart reconnect the device, then open the "USB Serial Converter" and uncheck "Load VCP" I hope this helps... The crash is strange, I get the following when the device is blocked by COM:

Hi @Walid Regarding your question in message: The power supplies can also be used as slow AWGs controlled by analog-out functions. For AD2 this was available in one configuration and for AD3 it is available in each configuration. Calling with FDwfAnalogOutNodeEnableSet(hdwf, -1, ... will apply to all 4 AWG channels (0=W1, 1=W2, 2=V+, 3=V-) So, make sure to call enable specific for each channel if you don't want to be applied on all 4 FDwfAnalogOutNodeEnableSet(hdwf, 0=W1 and 1=W2, ... (To be honest, I also made this mistake when writing the board test&calibration application.)

Hi @Walid

Hi @Oliver Kliebisch The ADP3X50 has device memory for 128Mi ADC samples, allowing capture on up to 4 channels at up to 125MHz. Recently device buffering support was added, which can perform up to 32768 captures with less than 1us latency. The averaging still needs to be done in software. The Analog Discovery 1,2,3 has memory for 2x16-32Ki samples and it does not support multi device buffering. The latency between captures is limited by the transfer to the host. The capture rate can be up to about 4k/sec
