Splitting 32 bit data into 8 and 25 bits for computing coincidence logic
Hello Everybody. I am working with Single photon counters in my lab. There are two separate TTL pulses that come from two detectors and fed to two channels in Counter that registers the arrival times...

Hi PRADEEP27, Your question seems a bit confusing as you have only 32-bit number, but you want to split into 6-bit (or 8-bit) number and 25-bit number, in which the total number of bits are 31 bit (or...

Simple solution, move to 64 bit OS, buy 64 bit LV, buy 1TB of RAM and run the code unmodified.Alternative:Remove memory hogs and leaks from the code. For the alternative, you should either learn the...
View ArticleRe: Network buffers versus RT FIFO versus Implementation Details
Hi nathand, I don't think that the white paper is clear about buffering. An RT FIFO can be seen as a buffer as well (being an array of values) and as such can also be used to compensate for read/write...

Hi makeway…, that error occurs when you read the VISA buffer too slow. You need to read faster (using deceased's single byte approach) or more bytes at once! I would read a fixed amount of bytes at...

All you need to do is some bitwise operations. For the first 6 bits, just do a right-shift by 26bits. To get the next 25 bits, do a bitwise AND with a binary number containing 26 1s and right-shift by...

Hi, I thought that wires had a unique name, even if they enter inside some "box" (while loops, cases). Instead, as in the picture below, I was able to assing different name "Timeout" vs. "TimeoutW", to...

As what altenbach suggested, going using boolean arrays uses more memory.I also did a mistake in the screenshot. Before splitting the array, it will look for the index array starting from the least to...

Hi Ee Lim, Altenbachs suggestions is still more efficient!Simple boolean commands and logical shifts are handled in a processor much faster than "complicated" math like division (as Q&R is a...
