--- Quote from: imolnar on October 05, 2022, 01:22:36 pm ---Hey guys, I built a version of this DIY LA. My scope doesn't recognize, when I plug it in. The outputs of the DS90.. are fine, but the scope indicates a constant low level. Any advice? --- End quote --- How did you check the LVDS outputs? This is a differential signal, it does not need to be measured relative to gnd, it is the voltage between pins 3 and 4 that is needed. It should change when applying 1 to pin 5. If this does not happen, the power supply may not be supplied or the chips are faulty. And it is absolutely necessary to check the flat cable - whether it is properly compressed (it should be 1:1, pin to pin, the keys on both connectors should be in the same position), there is contact on all wires. Did you remember to turn on LA in the oscilloscope? This is a very simple circuit, I'm sure you'll find the fault. |

S.P, just a quick question, how did you generate the board view for this project? i have been using altium to generate PCB files and have not seen a board view quite like that.. very handy for loading a board manually. i searched easyeda's wiki and didn't see anything.. |

Start browsing here: https://easyeda.com/forum/topic/Extension-User-Extensions-for-EasyEDA-Summary-9e065b68316f4491a3911dc6204be31e Altium is too expensive and cumbersome thing, I don't use it. :) |

Thanks for that.. I have been using Altium for the past 15 years, i have tried to use EasyEDA and KiKad, but i keep trying to use the fast keys for Altium.. i really need to do a full project in either to become more proficient. |
