Basic Pendant with 7i73

Thanks, can the 7i73 accept an MPG wheel that only has single sided inputs (+5v, -5v, A+, A-)?

This is how I got a MPG going on a 7i763 using its MPG input. It should get you going with using it.

I'm going to assume you meant (+5v,GND,A+,B+) so yes that's the only sort of encoder that the 7i73 accepts. I guess the logic is that any encoder would be physically close to the 7i73 (in the same enclosure even), and therefore doesn't need differential signaling. Also as it's probably going to be used to adjust values up/down it doesn't need index either.

Hi all.

I'm about to stumble down this path myself and have a couple questions off the top.

I have a Newhaven NHD-0420E2Z-NSW-BBW display which is listed as a 5v display, though it seems the logic on the 7i73 is 3.3v? is that just the GPIO or does that include the display pins as well?

I am currently trying to get through the Hal manual ( having a hard time...) is there a way to directly control an output pin on say a 7i76 from a button press at a 7i73?

Thanks!

more questions to come

I use 7i73 with 5V LCD without problem.
But be aware that quite a lot of such displays make trouble with brightness. Have quite a bunch that expext slightly negative voltage at that pin. So I often have a " helper" circuit with lmc7660.

Thanks for that. I now have the lcd going on a 7i83

now to get the scales and spindle going...

The Costs are running high on this project
can you give me a "Special NEED " or is it only can it be Done

a Big DRO Display at Atmel component up to 4Inch can be done on mutch lower cost
and as i mangiend earlier a ready made one like hb04 benefits more then the 7i73 with all the work goiing in
