Great news mate! How can the coupling problem be fixed, so what's needed? |

The Hantek driver didn't support coupling, that is the main reason for current lack of support. Now to an analogue signal question. I have enabled the 1kHz pulse, is there a possibility that this pulse causes noise in the signal sampling? Or is the pcb signal path properly shielded ? |

Nothing is shielded on the pcb, it's just 2 layers. From the board picture it can be seen that the top ground is opened over the 1kHz trace (which is on the bottom). The analog signals are "embedded" in the top analog ground section, so they did a bit of isolation. If you can't see any 1kHz artefacts at highest gain, i wouldn't call this an issue. Any chance to get the actual firmware? |

Thanks, a working blob would be nice, as i actually wont setup the build environment. Please check your mails. :popcorn: |
