I've combined a couple of tutorials I found on Adafruit to have a TMP36 sensor running with visual results shown through a RGB LED. If the temp exceeds a predefined temp then the light turns red, otherwise it stays green. After the loop runs 85 times the LED stops responding. I tried to incorporate PWM.cleanup() but that didn't help.
Any help would be appreciated. import Adafruit_BBIO.ADC as ADC import Adafruit_BBIO.PWM as PWM import time sensor_pin = 'P9_40' red = "P8_13" blue = "P8_19" green = "P9_14" PWM.start(red, 100) PWM.start(blue, 100) PWM.start(green, 100) count = 0 ADC.setup() PWM.cleanup() while True: reading = ADC.read(sensor_pin) millivolts = reading * 1800 # 1.8V reference = 1800 mV temp_c = (millivolts - 500) / 10 temp_f = (temp_c * 9/5) + 32 PWM.start(green, 100) # reset green light off PWM.start(red, 100) # reset red light off PWM.start(blue,100) # reset blue light off count = count + 1 if temp_f < 82: print('Normal Temp -- (COUNT=%d) Celcius=%d; Fahrenheit=%d' % (count, temp_c, temp_f)) PWM.start(green, 0) else: print('DANGER -- TOO HOT (COUNT=%d) Celcius=%d; Fahrenheit=%d' % (count, temp_c, temp_f)) PWM.start(red, 0) time.sleep(1) -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
