[time-nuts] TAPR TIC Upgrade?

2019-08-14 Thread Mark Sims
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

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? Bruce > On 15 August 2019 at 11:18 John Ackermann N8UR wrote: > > > In theory,

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. John On

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

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 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

The TICC uses an Arduino, not a Raspberry Pi. It would require both major hardware and software changes to utilize an RPi. On 8/14/19 1:28 PM, Perry Sandeen via time-nuts wrote: > Yo Bubba Dudes!, > I've just purchased a TAPR TIC module.  Now the new Raspberry Pi Model B has > just been

Yo Bubba Dudes!, I've just purchased a TAPR TIC module.  Now the new Raspberry Pi Model B has just been released. So my question is would there be any worthwhile advantage to replacing the TAPR unit with the new Model 4B? Regards, Perrier ___ time-nuts
