DS 데이터시트(PDF) – Dallas Semiconductor

Here is my program: Hi everyone, I’m working on a weigh scale with a strain gauge connected in the input RA2 of a pic 16F Mon Nov 09, You should turn off the comparators as part of your initial register setup.

Did you have a negative voltage between pin 2 and 5 on the D-Sub?

The pic is coded in mikroC and my problem is at the level of the connexion between DS it’s a max without capacitors and the SUB-D port the circuit datasgeet be able to connect to a pc. Does not include photo attachment. What you can see in the video is: Users browsing this dataxheet Finally the pic dials a phone number through the modem to alert the user. Do you know if there is an off-the-shelf version of a picture sending auto dialer???

Make sure there is 1 ground across both systems.


Once the call has been made and the modem detects that the call is ended, it returns a numeric datasheeet that the pic receives and change to detection mode again. Grounds and Vdds are hidden with proteus so I don’t think problems come from there.

A passive infrared sensor PIR is waiting for a person to enter a room. Do they make a digial sensor that will work or is there a attachment that will change analog to digital. No registered users and 9 guests. When it is detected the pic dials a fixed phone number and the user will receive the alert.

Since it is analog it does not work on digital phone lines. I have an inexpensive motion sensor auto dialer that dials my cell phone if it detects motion. Mon Dec 31, 3: The modem is turned on and the pic configures it to disable command echo, change to return numeric responses and turn off the volume of the modem speaker.

Hi, thanks for your reply.

If some movement is detected, it reports to a pic microcontroller. Finally I changed the sub-d port and now it works however don’t know if in reality it will I have an old external b.

You are talking about a camera and send the picture through MMS or email. I have soldered some wires directly to the modem 1 for GND, 1 for 5 v. The user has 15 seconds datwsheet leave the room, then the pic waits a motion detection.

It is more complicated.

In the same way I used the ds because it can communicate with a serial port without a capacitor unlike MAX I would love to find a device that dataseet do the same thing and send me a pic.
