Laser constantly pulsing in no scanning mode? #22

Closed taliaxu09 closed 10 months ago

taliaxu09 commented 11 months ago

Hello! Great project! Thank you so much for developing this.

I originally thought that the laser is only pulsing when "start" or request batch is pressed in the PC utility in no scanning mode, however, using a photodiode, it seems that the laser is constantly pulsing at 1KHz even with no command from PC utility. I just wanted to check that this is as designed?

Hello. You are right, but it is mentioned here: https://github.com/iliasam/OpenTOFLidar/tree/develop/Firmware in readme.md Blinking is controlled from main.c

That makes sense! I was a bit confused by the utility because I thought maybe pressing start initiates the 1 kHz pulse until it's done sampling

I measured the waveform at J2 and I think this looks pretty good (Laser voltage is 16V)? 20231109_130139

Thank you again for making this project!

I think that shape of the signal is OK.
