Hi,
I'm now beginnig to code my project
Could anyone refer me to where i could get code snippets to help me start coding. I'm using MPLAB and looking to code in C.
I attached my algorithm for Incoming calls and Outgoing calls. I also attached a ppt of my progress report so you could get a general idea of what i'm trying to do. My circuit is basically connecting the telephoe to be monitored in parallel to the telephone company's TIP and RING lines which then feeds to a MT8870 DTMF decoder whose decoded output goes to the PI18F452. There's also an off-hook detector and ring detector at the input side of the PIC. I'm using the DS1307 RTC to do timing together with 24C08 memory modules for logging and storage of passwords. Everything is displayed on an LCD connected to port D pins of the PIC. I attached everything in parts as i found them on the net and using in my circuit.
1) lab2 shows how i connected the LCD.
2) Testing MT8870 DTMD decoder shows the input configuration
3) Detecting a telephone RING 1 Electronic Circuit - CircuitsArchive - Show2 the input to a 4N25 chip to detect ringing signal together with counting when its output is connected to the PIC through a pull-up resistor.
4) Off-Hook Detector
5) DS1307 together with 24C08 memory - the 24c08 replaces the at24c128 shown in the diagram
6) Activating electrical lamp.
Any any any help at all would be great because i only have a month left.
