2017-06-25 Thread EB4APL
Maybe I'm missing something, but Arduino programs are usually distributed as source code. If this is the case, the I2C address of the display should be not a problem. If the problem is due to the display library used, you can use another library that can be initialized with the right address.

Working in motorsport, we used the Deutsch Autosport series. They're based on military connectors but are lighter and possibly cheaper. Still far from cheap, but high density, high reliability and MUCH easier to assemble than Lemos. Usually crimped pins and raychem heatshrink cable entry. https://

Dave will guess you are sub sampling the 10 Mhz ref. Yes it should be 4.7K. Not sure why but old military gear resistors were like that. Circa 1942 at least in schematics I have seen. Regards Paul WB8TSL On Sun, Jun 25, 2017 at 2:25 PM, David C. Partridge < david.partri...@perdrix.co.uk> wrote: >

Hi The simple answer is that it’s much more simple than that :) The 4100 and 6100 both run a very rudimentary serial command set. It’s not quite SCPI, but that’s the idea. With a simple terminal program (any terminal program ..) you can bash in the four or five lines that get it doing what you

Our favourite auction site has someone selling a Spirent GSS4100 GPS simulator cheap, "for parts", as it is untested. I'm guessing the vendor has no clue HOW to test it, especially as they have no software to go with it, so am hoping it might actually be OK. Worth a punt, anyway. However, the do
