how do i make lm75b as the interruptin to be event triggered?
osMode(); /** Set the OS pin mode of the LM75B * * @param mode The new OS pin mode as an OSMode enum. */
i am working on a project that i think i have to use event triggered interrupt, when my mic voltage is above threshold, interruptin will rise so it will be a HIGH and vice versa. i am having problem making the lm75b temperature as a interrupt. i know that i have to use osmode to configure it and stating its default address.do i have to solder a wire to from the os which is pin 3 to somewhere?can someone share with me to how to configure it as an interrupt.thank you
#include "mbed" #include "LM75B.h" AnalogIn rightmic(p16); InterruptIn sensor(p28, p27);//supposely this should be LM75B Timer t; void right() { t.start(); float sample=rightmic.read()*3.3; printf("%f",sample); t.stop(); printf("%f", t.read()); t.reset(); } int main() { while(1) { sensor.rise(&right);//if it is a HIGH it will run the function of right. } }
this so far what i have tried.
