Embedded Micro

I should have thought about this! I remember playing with the trigger_sync, but I never put it in the if. It reassures me that the answer is so simple and elegant. One question: is it the fact that the output of the two flipflops is more "stable" than the external input that solved the issue? I have...

Hey!

Do you think the error could lie else where than in my lucid code?

If the video is accurate, it is very strange that all the numbers will come one after the other but in disorder.

Could some interpreter/compilater be incriminated?

thanks!

Sure thing! The password is "mojofpga": https://goo.gl/Bfgib5 There is the project, and a video I took from the led blinking (which shows the value of the counter used in the "distributor", the numbers seem to come in disorder). Usually, I send a square signal~4Hz (120ms up, 120ms down, etc...) and ...

So i tried a new approach (more adapted to the synchronization of four lasers): A distributor module modifies the trigger sent to each laser according to a 16bits sequence. module userinput ( input clk, // clock input rst, // reset input new_rx, // new RX flag input rx_data[8], // RX data output mod...

This is true, you mentionned that earlier and I didn't take the time to modify it. But I'll take your advice. Concerning the led and the constant sequence, I tried that. The sequence I send via usb is correctly understood. When using a constant sequence the problem stay the same, therefore I believe...

Hey! Worked like a charm! I didn't have time to implement it on the microscope until now, it is really great. Much better than the Arduinos I had. Now people are using it daily for the lasers. Which bring me to another step. Because I bought another Mojo and want to expand its functionalities. Basic...

Hey! I finally got the time to try out with the lasers. Unfortunately, something that I didn't notice but that I can actually see with the oscilloscope is that it is skipping some triggers... Something like: I use what you wrote: module triggerToPulse ( input clk, // clock input rst, // reset input ...

Hmm oki, that indeed works much better that way! Somehow I thought when going from idle to listen the flag was still up.

In the mean time I solved my issue with the pulse length. I was sending highbyte and lowbyte in the wrong order...

thanks a lot for your time!

Ah yes sorry, of course... I took the module you wrote as is, and the other module is the one I posted. But small modifications I made might be the source of my trouble. NET "camera" LOC = P22 | IOSTANDARD = LVTTL | PULLUP; NET "sigout" LOC = P33 | IOSTANDARD = LVTTL | PULLUP; module mojo_top( input...

For the moment it is quite funny, because by sending two times the command, then I get the right behaviour. But I haven't manage yet with an end character... An other of my trouble is that the pulsing doesn't work. If I set in the code a fixed duration (like 200), then i get the pulse with the right...
