Hi guys,
There is a task to acquire data from analog sensors using cRIO 9076 + NI 9234. The task is solved with FPGA and FIFO buffer (code segment is attached). Sample rate is 200 Hz. I disconnected all sensors. During debug I have an issue of appearing "bursts/needles" in the data. I was not able to find out a reason for it. What is typical, when I start topLevel VI and it receives the first package, the "needle" immediately occurs in the data (see graph in the upper left corner) and this is repeated in 8 out of 10 cases. The needles appear without any specific periodicity and affect all
