16. initialize lcd start the adc to measure temp read adc byte convert adc byte into temperature and record into the flash increase no of samples by one display temp on lcd compare the temperature with the threshold value waiting time according to recording interval start the conversion of ADC..conversion frequency is around 640KHz convert adc digital output into temperature and store its 2 digit value into flash increase number of samples by one convert decimal to hexadecimal value add one to hex value of no of samples convert hex value to decimal number Algorithm
17. display 2 digit temperature to LCD compare temp value with threshold values hex value of current temperature hex value of threshold temperature LED on if current temperature more than threshold value LED off if current temperature more than threshold value provide measuring interval delay converts the adc 8 bit output to 2-digit temperature value in ASCII convert the 4 digit decimal into 2 byte hex Input in t3 t2 t1 t0 and output in hex1 hex0 provide threshold value range from 20 to 49 degree celcius for user provide recording interval range from 01 to 99 secs for user display a 16 byte in ASCII string on LCD send the command to LCD send ASCII data to LCD
