/**************************************************************************************** * Notice: When compiling, be sure to use the flags -lX11, -lpthread and of course, * * be sure the DLP-2232PB-G is plugged into a USB port. I use: * * * * cc -Wall -lX11 -lm -lpthread -o thermometer_monitor thermometer_monitor.c * * * * Pin 5 (AN1) of the DLP-2232PB-G is being used for the input. Remember, its * * input impedance is quite low and a preamp may be necessary. * * * * Edit main() to try the various capabilities. * * The thermometer routines need a pull-up resistor. See ds18s20 spec sheet. * * * * Study the 16F877A port specs carefully. Different pins/ports have varied * * capabilities - Schmidtt trigger, open-collector, TTL * * * * Written by Craig Van Degrift * * http://yosemitefoothills.com * * * * This demo code is only a best effort. Use at your own risk. * * Uncomment the function calls in main() to try the different capabilities. * * * * Consider this code a framework which will need considerable modification * * to meet the needs of a particular measurement task. * * * ****************************************************************************************/ #include "core.h" const char* device="/dev/ttyUSB1";
