| Abstract: | In the SLED temperature control system, the semiconductor laser's temperature is set by the computer, and USB is used to realize the communication between the computer and target board. The automatic temperature control unit, including pulse width modulation(PWM), PID algorithm(PID) with the single-chip, is designed based on the semiconductor cooler's (TEC)characteristics. We select the CY7C68013 as USB communications module and the 12 bit of the A/D converter collecting data; the PC client software, based ... |
