  1. Hi guys: I need know how create a Custom Command in LINX for read a encoder of two square pulses from the digital pins of Arduino in LabVIEW. Thanks.
  2. Hello, I have found this topic with script for counting edges of digital signals and I wonder if it's possible to modify it somehow (or use completely different approach) to read quadrature encoder signals with Analog Discovery? Most important thing, I think, is that I have to compare signals state at current event (i.e. I have "1" on signal A and need to know what is the state of B signal in that particular moment) and be able to compare it with previous state (event) to decide if I should increment or decrement my counter. And it should be triggered with both edges but I assume that trigger options on DIO line decides when events are generated. Is it possible to capture and count edges without sample count limit? I mean something like hardware triggering on digital inputs instead of starting on first trigger and sampling defined number of samples with defined frequency (Stream mode). At the moment it looks more like signals recording and post-processing (offline) and I wonder if it is possible online to execute encoder script live on each trigger? It's not a must but would be nice And one more thing - I have downgraded my WaveForms to version from mentioned topic because in newer version there is no Stream mode. Was it renamed or replaced by something better?
  3. Hello everyone! I have been working on a jpeg encoder for Xilinx boards. Here you have the result. If you are seeking for one minimal JPEG encoder without opencv that you can run in Standalone embedded systems you have to look this: JPEG encoder Enjoy! See you soon!
  4. How to use two encoder in myrio and diglent NI myrio motor adapter. Myrio A expansion port has only one direct encoder pins (pin 18 and 21). But in digilent motor driver there are two encoders. Is there any direct usage in LABVIEW or can anyone help me in programming additional encoders
