Hi, FDwfDigitalInSampleSensibleSet did the trick! The behavior thru SDK now matches the GUI behavior. Thank you for your fast response! //Tood

Hi, I am sampling DIO 7 from wavegen GUI. The mode is record without triggers. Sampling rate is 4MHz. I am using 16x16k buffers. The results are perfect. No corrupt samples (see picture below). When I am using sample code digitalin_record.cpp as base and sampling above 2MHz the result is a lot of corrupt samples. See attached C file digitalin_record.c. My OS is win10 and the compiler is gcc. Output from digitalin_record.exe: $ ./digitalin_record.exe Open automatically the first available device Starting record... receivedSamples: 93743 discardedCorruptSamples: 83844 sample:0 pinstate:0x01b9 sample:1 pinstate:0x01b9 sample:2 pinstate:0x01b9 sample:3 pinstate:0x01b9 sample:4 pinstate:0x01b9 sample:5 pinstate:0x01b9 sample:6 pinstate:0x01b9 sample:7 pinstate:0x01b9 sample:8 pinstate:0x01b9 sample:9 pinstate:0x01b9 sample:10 pinstate:0x01b9 What is wrong with my implementation? Best Regards, Tood digitalin_record.c

Yes! That solved my problem! Thank you for fast response! Best Regards, Tood

Hi, I am trying to implement spi_spy thru SDK. My C program, based on Digital_Spi_Spy.py, decodes correctly about ~90% of the data. Sometimes it seems to loose trigger and the rest of the frame is corrupt. The WaveForms Protocol->SPI->Spy works perfectly every time for my setup. Included is my C code and a .jpg from my and WaveForms output log. The faulty data is marked as yellow in the left log in the picture. I am writing in C and the spi frequency is 300kHz settings are active low, cpol 0, cpha 0. Is there something I am missing here? How is SPI Spy implemented in WaveForms? Best Regards, Tood hello.c
