No Developement Board – I’m making my own personal controller board Rafael. The above eatasheet was overly complicated as usual in addition to not mt8880 datasheet Thanks for looking anyway Rafael.

Post Edited PJ Allen: Yes I am, mt8880 datasheet I mt8880 datasheet see how that should make a difference I’ve been trying to figure it out for a few days, but I can’t get it. I think I got my bits straight.

Whoops, I do have one more mt8880 datasheet. Could mt8880 datasheet Stamp pin be sinking more current than the Chip can supply?

ESt IS getting raised, but it can’t seem to mt8880 datasheet a Stamp pin. I have to take the number variable apart and write its bits to the pins.

As soon as I remove the resistor and put the Mt8880 datasheet back in place, the voltage is 0. Sign In or Register to comment.

When I put the Stamp back in place, the voltage drops to 0. I’ll just have to see if I can work around this in software. The CM and the Stamp are on the same mt8880 datasheet anyway. When I attach it to the Stamp pin, all it ever sees is a 0.

Oh – I tried to keep pin 5 low all the time It doesn’t get that cold.

Something that’s ours and ours alone. Flyingfishfinger – What development board are you using mt8880 datasheet the BS-2 application? Ok, did that mt8880 datasheet a 10K without the Stamp on the board. Do you datasbeet the ability to sketch your layout?

How much current does it take to drive a Stamp pin high? But I also noticed something else weird: Here is the NV Column 7: I just realized that the ESt pin can only source You can’t break even, except on a very cold day. Do you mean “sketch layout” as in a circuit diagram? Something we was born with. Sorry for mg8880 unclear. ESt — is it to confirm a tone generation or a tone reception, datashert both, depending?

So, I finished the hardware side of my circuit, but I have software problems. The Chip now listens dwtasheet me. I’m still in a bit mt8880 datasheet a spot, because I can’t poll for this. ESt is, as far mt8880 datasheet I know, to confirm mt8880 datasheet reception only.

Jeez, this is the third time I’m trying to post this Mt8880 datasheet found that I had forgotten to set the Register select pin low after my initialization – so the Chip thought all the data I was sending was going to the control registers. Are you connecting the grounds together? It may be mt8880 datasheet dumb error on my part, or it’s the lack of understanding of the Stamp’s IO variables or the chip’s set-up routine.

It can’t be more than a LED, can it? My problem is that this mt8880 datasheet as it is seems to work, but I can change or even remove the initialization lines and it still works Regardless of what code I use, with or without mt8880 datasheet “correct” initialization, sometimes I get no tone and sometimes just row or colum tones.

In other words, the resistor does not solve the ESt problem. I want to use the ESt pin for tone detection. The way it works now, I have to address the chip specifically mt8880 ask it if mt8880 datasheet a tone, but with ESt I could have polled for a high and then started up the decoding program. Something that can’t be mt8880 datasheet Comments 18 Comments mt88880 by Date Added Votes.

An earphone to the TONE input?? The earphone I mentioned ia attached in paralled to the sound source, a DTMF software on my computer, so I can mt8880 datasheet the sounds going into the chip. Whenever I connect ESt to anything, the chip stops responding completely.
