Sample & Hold, did they go out with the buggy whip?

I can't see how an OS would enter the picture, other than if you want all the code served on a silver platter

Hmmm, I've never married a nun. Am I missing something?

Lol, a fairly intelligent lady I dated once was discussing stocks with me and I suggested some semi stocks which were rather depressed at the time. When I got to Analog Devices she said, "I'd expect them to be going out of business soon!" lol At the time they were duking it out with TI for dominance in the DSP world.

Why on earth would you want to write your own drivers for the complex devices which are sold as MCUs these days? ARMs are not PICs.

You know what they say about those Catholic girls!

Then they should get out of the processor business. They used to be really good at it for decades, like when I dealt with their 16-bit DSPs in the late 80's and early 90's. Back then everything worked right off the bat and without springing a surprise of having to buy some extra software that costs as much as a luxury car.

It depresses the reputation of the company selling the resulting parts. They need to pay more attention to such details.

That is indeed horrid.

We were told that you need a special driver that is only available in a certain OS which costs big bucks. That was a major bummer.

Other times promised stuff didn't work and we now have to resort to writing our own driver or bit-banging. That puts a major crimp into a project schedule.

Because the shipped ones don't work?

Hey, I married one :-)

Revisiting the lyrics to Only The Good Die Young (1977), I can see why it was controversial in its day.

I need something that will not draw more than 50uA off the 3.3V rail. The 74HC2G66 does this nicely. The charge injection argely cancels out due to diff-mode and what remains can be calculated out. It won't matter much anyhow because the switch capacitance is similar to all others and when the source gets powered up or down this will cause more "charge injection" than the mux action itself.

A nun? Wow!

No, a Catholic girl :-)

Depends on what drivers, I'd rather not have to write an ethernet or USB driver because that involves usually a lot of protocol, and I'd rather not have to write all the registers definitions because that is a ton of tedious typing

but for serial interfaces, timers, etc. it is no different than a PIC,

Aren't all Nuns Catholic?

Me too.

No, there are Orthodox and Anglican nuns, as well as other religious communities of various shapes and sizes. (Orthodox nuns are called something else usually, but they live in all-female monasteries.)

And of course some of the older RC nuns are hardly Catholic at all. ;)

We do ARM boxes bare metal, with Ethernet and USB. I think we may crib some of the Ethernet stack code from somewhere. SPI and ADCs and such, we just do in C.

We plan to do web pages and some Javascript in some upcoming boxes, and my coder guy is happy to do that bare-metal, too.
