After one week trying to read a temperature using stm32f103c8t6 and a LM35 I found that the only thing missed was a 10uF electrolitic capacitor between groung and signal pins of the sensor. Now it is working right.
History
stm32f103c8t6 using a LM35 sensor. Use a 10uF electrolitic capacitor between groung and signal pns of LM35.
