Re: Encoder switches - trying to get a handle on how to use properly...
Yes, even I managed to make the software for a encoder of this type work, and that says something! Good thinking really that quadrature stuff... ST

Re: MAX232CPE & MAX232N - I don't understand the difference?
Thanks guys, I will double check the data sheet again to see if I can "Get it". If not, I guess the next best thing is to drop it in a socket and give it a try. I have a working module setup right now

Re: MAX232CPE & MAX232N - I don't understand the difference?
most often this suffix is the package and temperature range. As long as it fits it should be fine. But beware, there were -R versions of ICs that were mirrored upside down! Ideally check the

Re: SPI interfacing - How long can external connections be?
Roy, I will do when I get the cable in that I plan on using for this. By chance, can you give me a hint as to what sort of good and bad things I should be looking for? Right now, my technique on the

MAX232CPE & MAX232N - I don't understand the difference?
Hi Guys, I have a number of MAX232 chips on hand. Some are marked MAX232cpe and some are marked MAX232n. I tried to gather up what the differences are from the datasheet, but all that did was confuse

Re: SPI interfacing - How long can external connections be?
It does appear that 20 feet of cable will work for SPI. The length is approximate, but I think it is close to 20'. The speed at which I am communicating at though is a bit confusing based on the

Re: SPI interfacing - How long can external connections be?
HI ROy, In reality, I would have been very surprised had it worked! When I was first working out some serial communications software about 20 years ago, I used all short cables and PC-PC for testing.
