PicBasic Pro, PicBasic, BASIC Stamp, Microchip PIC, 8051, and Remote Control Projects

ADLog is an advanced analog data logging software application for monitoring and logging analog voltages. Features include display of voltages on an analog meter, strip chart, scrollable history buffer, user configurable High and Low alarm voltage triggers, sample count display, log event counter, LED indicators for high/low alarm status, automatic time and date stamp of each log event with alarm trigger voltage, automatically creates separate alarm log files for each day, and much more.


Download & test drive the demo version HERE

The demo version is the same as the full version, but with a limit of 100 sample counts. Example source code for the PicBasic Pro and CCS C compilers are available in the demo .zip file, and below. Please see the readme.txt file for instructions.

And here's a complete schematic with source code for a tiny 8-pin PIC12F683 configured to read a 0-5 V analog signal and send it to the ADLog software with 10-bit resolution.
