Any further thoughts on my questions regarding pre-configuration and frame errors?
In the meantime, I have sent two pull requests for easier tracking/discussion: 1. https://github.com/sigrokproject/sigrok-dumps/pull/33 2. https://github.com/sigrokproject/libsigrokdecode/pull/55 BTW: https://sigrok.org/wiki/Protocol_decoder_HOWTO#Submitting_your_decoder should be updated to mention that pull requests on GitHub are a possibility :) On Sat, Oct 10, 2020 at 6:24 PM Michael Stapelberg < michael+sig...@stapelberg.ch> wrote: > One issue with stacking the SCS decoder on top of the UART decoder is > that both of the attached signals decode successfully (with good CRC > checksums). > But, in reality, my intercom doesn’t accept this signal: > > https://t.zekjur.net/2020-10-10-scs-broken.jpg > compare to a working signal: > https://t.zekjur.net/2020-10-10-scs-working.jpg > > I think this is because the UART decoder only samples at 20%, > and if the signal just stays low, that’s good enough for the UART decoder. > > But for SCS, we should ideally raise a frame error when the signal doesn’t > return to the bus voltage. > > BTW: Is there a way to pre-configure the UART decoder? > Currently, when adding an SCS decoder, > I need to select “uart”, > change baud rate from 115200 to 9600, > set sample point from 50% to 20%, > select the data line in the SCS decoder. > Could all of these be automated away somehow? :) > > On Fri, Oct 2, 2020 at 8:46 AM Michael Stapelberg < > michael+sig...@stapelberg.ch> wrote: > >> Valerio, thanks very much for reaching out and offering to help! >> >> Please take a look at >> https://michael.stapelberg.ch/posts/2020-09-28-nuki-scs-bticino-decoding/ >> where I describe in detail and with pictures the setup that I use. >> >> Let me know if you have any additional questions after reading that post >> >> On Thu, Oct 1, 2020 at 11:56 PM Valerio Messina via sigrok-devel < >> sigrok-devel@lists.sourceforge.net> wrote: >> >>> wich hardware are you using for capturing SCS with sigrok? >>> My home is all made of BTicino MyHome domotics, I can capture more than >>> intercom if needed.
