Electronics / led of different color
« on: July 21, 2017, 09:56:33 PM »
Hi, Daniel,

I am thinking about buying LED and filters for red color. I found that LUXEON has 2 square mm LED of lime color which fits spectra of the filter set I want to have. But its forward voltage is slightly different from the blue one (2.75 V vs 2.95 V). Do you think this lime LED will work with the camera PCB? Thanks a lot.

Thanks a lot, Daniel. It is easier to solder an coax cable than changing codes.

Hello Daniel,

I was trying to externally trigger the miniscope, but could not make it work. I have the version 3.2 daq and assume the digital port 1 is the "trigger in" since the digital port 2 sends out TTL pulses corresponding to individual frames. I first connected the scope with the miniscope controller by pressing the "connect" button. The weird thing was that when I selected "trigger ext", the "Record" button became grey and inactive. Then if I pressed the "connect" again, "record" button came back. But pressing the "record" button did not make the camera run even when digital port 1 was high. Do you have any idea of what could be wrong? Thanks.
