Re: Input from a serial mouse

Sorry if I hadn't mentioned this earlier, it's just a standard two button mouse from Microsoft. DTR and RTS are both connected to power, which is +5V. Everything I can find seems to say this is correct. Then the RX and TX pins are just connected to the Max3232, and the ground pin is connected to gro...

Re: Input from a serial mouse

Cool, I hadn't seen that site. Thanks. It doesn't seem all that much more complicated though - according to that site all I do differently is connect pins 4 and 7 on the mouse to 5V. I'm confused though when it says that the transfer pin on the mouse must remain low - does that mean it shouldn't be ...

Re: Female -> female serial connection?

By power do you mean just plain 5V would it be something more complicated?

Re: Female -> female serial connection?

Thanks for all the helpful posts! I found this site which provides a great description of the mouse. I just wanted to make sure I had this wiring right though, since so far I'm still not getting anything - I have a wire going from RX on the mouse to T1OUT on the Max3232, another wire from TX on the ...

Re: Female -> female serial connection?

Sorry, I forgot to mention that the serial would be connected to the Atmega through a Max3232.

So converting from female -> male serial isn't just as simple as putting wires in the female ports and plugging the wires into another female serial port?

Input from a serial mouse

I have a mouse with a female serial connection, and I'd like to try to use it as an input for my Atmega 168. I have this connector for connecting a male serial end to the breadboard. The problem of course that's a female connection and my mouse has a female connection. Can I just connect the two fem...

Re: IDC->breadboard easy connector

Ah cool, I hadn't seen that. So could just solder this header onto the board, and then solder wires from the board to my breadboard and use that to program my AVR? I would be connecting that board to this board, since my laptop doesn't have a serial port.

IDC->breadboard easy connector

I'd really love an easy way to connect an IDC ribbon cable to my breadboard. The reason I can't use something like this is because while it fits the cable's .1" spacing, it won't bridge the .3" gap down the center of my breadboard. I've tried finding a connector like this, but with no luck. Would su...

Re: Accelerometer giving inconsistent readings?

Oh, I see. Why is that, that the acceleration would be different at different rotational positions? Because of the force of gravity, acting at different angles?

Re: Accelerometer giving inconsistent readings?

Awesome, this seems to be working better now. When sitting still, the data is always clustered within 20 units of each other. But I'm still a little confused by it - when I move it along one axis the data changes, but it seems kind of random in how it changes. Sometimes it drops a hundred units, oth...

Re: Accelerometer giving inconsistent readings?

Alright, I'll have to solder new wires onto the breakout board and will post back if I still have the problem.

Thanks!

Re: Accelerometer giving inconsistent readings?

Oi, the wires are pretty long between the accelerometer and breadboard. Would cutting down that size work?

I thought capacitors would help even out the output?

Accelerometer giving inconsistent readings?

I've got this accelerometer hooked up to an Arduino, as shown here . I get readings for all three axises, but the problem is they don't seem accurate - they fluctuate from around 375-550, even when the accelerometer isn't moving at all. I do have .1 uF caps in between the accelerometer outputs and t...
