Re: [time-nuts] TAPR TIC Upgrade?
I've almost done that, except not with pi, but a whole PC (Lenovo Tiny windows 10 box) and a touch screen display. Heck, throw in Rubidium, too. Then re-thought about it. I could end up with a giant headache to sort out packing all that noise and heat generating component into one case. Right now, in 2U case, only TICC sits. --- (Mr.) Taka Kamiya KB4EMF / ex JF2DKG On Wednesday, August 14, 2019, 11:18:37 PM EDT, djl wrote: Would require a real time operating system on the Pi?

[time-nuts] TAPR TIC Upgrade?
Well, I've done that... sort of. I'm still using the TAPR TICC, but have it connected to a PI-3B / official PI touch screen mounted in the excellent SmartiPi case running Lady Heather. Heather can configure the TICC and capture TICC data to a file while simultaneously calculating and plotting the data and ADEV/HDEV/MDEV/TDEV/MTIE of both channels (can do 4 channels with two TICCs). The TICC data can be sent in real-time out a serial or ethernet connection and/or the file can be processed by Timelab or Stable32 or whatever (they do much prettier plots). The PI3 has no problem doing the processing. It remains to be seen if the extra speed and memory of a PI4 will be useful. I've been contemplating doing a front end for the TICC with things like a switchable terminator, polarity selection, variable threshold, internal/external reference oscillator selection, etc. -- > The main benefits would be the bigger RAM on the 4B and the ethernet port. > If you went crazy, you could put a display and buttons on it and have an “all in one” instrument. ___ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
Re: [time-nuts] TAPR TIC Upgrade?
Probably only worth the effort if one were considering a higher resolution device intended to surpass that of the venerable HP5370A/B or equivalent. Doable with off the TDC shelf parts but is there any demand?

Re: [time-nuts] TAPR TIC Upgrade?
In theory, making a new TICC that ran on an RPi could provide significantly more measurements per second, and more convenient I/O, but wouldn't affect the quality of the results. I've thought a bit about an RPi-based TICC, but it's a significant redesign effort for limited gains.

Re: [time-nuts] TAPR TIC Upgrade?
More likely you would use a Raspberry PI (or similar, like the BeagleBone Black I use) as a logger, data capture front end, in conjunction with the TICC. I find it useful to have a reasonable performance Linux computer with a network connection, direct IO pins and SPI, I2C, Serial and USB bus that I can now script in Python or program in C and timestamp anything I choose with NTP time, and simultaneously capture the TICC data and log it all. Just plug the USB cable from the TICC into one of the USB ports on the RPI or BBB and a GPS 1PPS signal into one of the GPIO ports and/or one of the TICC ports. I do any post-processing and plotting of the logged data on a desktop computer, not the little Linux data capture computer. It is real awkward getting a signal like a 1PPS edge in or out of a desktop directly. --- Graham == On Wed, Aug 14, 2019 at 5:06 PM Forrest Christian (List Account) < li...@packetflux.com> wrote: > The TICC uses an Arduino mega clone, not a Raspberry Pi. > > My understanding is that most of the magic happens on the shield board not > in the processor - the processor is just there to capture the data from the > shield and format and report it via the serial port. > > On Wed, Aug 14, 2019 at 12:10 PM Perry Sandeen via time-nuts < > time-nuts@lists.febo.com> wrote: > > > Yo Bubba Dudes!, > > I've just purchased a TAPR TIC module.

Re: [time-nuts] TAPR TIC Upgrade?
Hi Could you? Sure you could. Should you? How much do you feel like rewriting all the driver software from scratch? Do you really want to rewire things to fit to the Raspberry pinout? That’s either a fairly simple PCB or a whole bunch of wires. The main benefits would be the bigger RAM on the 4B and the ethernet port. If you went crazy, you could put a display and buttons on it and have an “all in one” instrument. Probably easier to leave the Arduino where it is and mate up the 4B with the serial port on the Arduino.

Re: [time-nuts] TAPR TIC Upgrade?
The TICC uses an Arduino mega clone, not a Raspberry Pi. My understanding is that most of the magic happens on the shield board not in the processor - the processor is just there to capture the data from the shield and format and report it via the serial port.

Re: [time-nuts] TAPR TIC Upgrade?
The TICC uses an Arduino, not a Raspberry Pi. It would require both major hardware and software changes to utilize an RPi.
