Microchip PIC系列單片機RS232通訊應用

Digitemp Junior – An RS-232 Port-Powered Digital Thermometer Digitemp Jr. is a device that is designed to measure and report ambient temperature. When connected to an RS-232 port on any PC, it will periodically measure and report in ASCII form the ambient temperature in degrees Celsius. These temperature readings can be monitored with any terminal program. If the terminal program supports capture to disk, the temperature readings can be saved to disk for further analysis with a spreadsheet program or other data analysis tool. The simple ASCII output format of Digitemp Jr. makes it rel- atively easy to write custom software for receiving, recording, and analyzing ambient temperature data. Best of all, Digitemp Jr. requires no external power sup- plies or batteries. It is powered directly by the RS-232 port.

基于單片機的顏色自適應識別電路

　　為解決電致變色器件的顏色變化受外界環境顏色控制的問題，設計了一種基于單片機的便攜式顏色自適應識別電路。與傳統顏色識別電路相比較，該電路利用數字式的顏色傳感器來獲取外界環境顏色，產生的數字顏色信號易于單片機進行處理。在電路中，下位機部分主要負責獲取電致變色器件變色參數及控制電致變色器件的顏色變化;而上位機部分主要負責把下位機獲取的電致變色器件變色參數進行電壓到顏色的曲線擬合，并通過藍牙通信把擬合曲線參數傳遞給下位機。結果表明，該電路能自動根據環境顏色提供-4~4 V范圍步進為0.1 V的電壓來驅動電致變色器件的顏色顯示，與傳統的顏色識別電路設計相比，識別的精度和速度都得到了明顯改善。　　Abstract: 　　In this paper， a portable adaptive circuit for color identification(PACCI) based on MCU was designed. Compared to the traditional color identification circuit， the PACCI adopts digital sensor to detect the color data from external environment and further generate digital color data， which can be processed easily by MCU. In PACCI， the slave is mainly responsible for detecting the color parameters of the corresponding elcreochromic device and further driving it. For the master， which is mainly responsible for the color curve fitting based on the parameters of the electrochromic device， and transmits the fitting parameters to the slave through the bluetooth device. The results show that the PACCI can provide the basis voltage range from -4V to 4V automatically based on the colors of external environment with step as 0.1V to drive the corresponding electrochromic device. Compared to the traditional color recognition circuit， the recognition accuracy and speed of PACCI have been improved significantly.
