為解決電致變色器件的顏色變化受外界環(huán)境顏色控制的問(wèn)題，設(shè)計(jì)了一種基于單片機(jī)的便攜式顏色自適應(yīng)識(shí)別電路。與傳統(tǒng)顏色識(shí)別電路相比較，該電路利用數(shù)字式的顏色傳感器來(lái)獲取外界環(huán)境顏色，產(chǎn)生的數(shù)字顏色信號(hào)易于單片機(jī)進(jìn)行處理。在電路中，下位機(jī)部分主要負(fù)責(zé)獲取電致變色器件變色參數(shù)及控制電致變色器件的顏色變化;而上位機(jī)部分主要負(fù)責(zé)把下位機(jī)獲取的電致變色器件變色參數(shù)進(jìn)行電壓到顏色的曲線擬合，并通過(guò)藍(lán)牙通信把擬合曲線參數(shù)傳遞給下位機(jī)。結(jié)果表明，該電路能自動(dòng)根據(jù)環(huán)境顏色提供-4~4 V范圍步進(jìn)為0.1 V的電壓來(lái)驅(qū)動(dòng)電致變色器件的顏色顯示，與傳統(tǒng)的顏色識(shí)別電路設(shè)計(jì)相比，識(shí)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.

The MSP-FET430PIF is a Parallel Port interface (does not include target board) that is used to program and debug MSP430 FET tools and test boards through the JTAG interface. This interface is included in our FET tools, but sold without the development board. This interface uses a Parallel PC Port to communicate to the Debugger Software (IAR Kickstart software included) running on the PC. The interface uses the standard 14 pin header to communicate to the MSP430 device using the standard JTAG protocol. The flash memory can be erased and programmed in seconds with only a few keystrokes, and since the MSP430 flash is extremely low power, no external power supply is required. The tool has an integrated software Environment and connects directly to the PC which greatly simplifies the set-up and use of the tool. The flash development tool supports development with all MSP430 flash parts. Features MSP430 debugging interface to connect a MSP430-Flash-device to a Parallel port on a PC Supports JTAG debug protocol (NO support for Spy-Bi-Wire (2-wire JTAG) debug protocol, Spy-Bi-Wire (2-wire JTAG) is supported by MSP-FET430UIF) Parallel Port cable and a 14-conductor target cable Full documentation on CD ROM Integrated IAR Kickstart user interface which includes: Assembler Linker Limulator Source-level debugger Limited C-compiler Technical specifications: Backwardly compatable with existing FET tool boards.
