Introduction - If you have any usage issues, please Google them yourself
The ADC module itself a temperature sensor.
Formula:
Vsenso = 2.7 (T+ 55)/75
Therefore, the use of ADC measured Vsenso can calculate the temperature T:
T = (2.7- Vsenso)* 75-55
Temperature conversion results through UART output.
At room temperature environment, if the finger on LM3S1138 chip temperature will obviously rise several degrees Celsius If stick cotton dips in alcohol wipe the chip surface temperature will be significantly lower.
