![]() Disable the GBSControl and it all works when it uses the internal GBS8200 firmware. I switched the SDA and SCL lines just in case but no difference. I am powering it with a USB cable for testing purposes. I am using the standard Sync Stripper circuit with the LM1881 as followed below: [i found this project last week and it interested me to be able to try and clean my video up for my Geneve 9640 (outputs 15kHz)that is connected via RGB to the GBS8200 then out to VGA. I am using the standard Sync Stripper circuit with the LM1881 I have built the board based with a NodeMcu ESP8266 D1 Mini and followed the Wiki for hardware setup and uploading of the code. The LM1881 doesn’t provide a Horizontal Sync Output, you may get away with using the Composite Sync Output instead of it, it really depends on the display device. I found this project last week and it interested me to be able to try and clean my video up for my Geneve 9640 (outputs 15kHz)that is connected via RGB to the GBS8200 then out to VGA. the others that dont support it, they need some extra components to separate the video sync from the green channel, and that can be done with a LM1881. In some cases you might need to add electronics to remove the sync information from green picture component because some monitors dont work correctly with it.
