【導(dǎo)讀】利用新華龍公司的。C8051F020和第一代藍(lán)牙模塊芯片BCM-05,設(shè)計(jì)一個(gè)藍(lán)牙空氣粉塵檢測(cè)器,使之與藍(lán)牙接入設(shè)備搭建一。目前,藍(lán)牙技術(shù)已臻于完善。在局部范圍內(nèi),藍(lán)牙通信具有可靠性、安全性及容錯(cuò)能力強(qiáng)等優(yōu)點(diǎn)。現(xiàn)場(chǎng)環(huán)境中將可以發(fā)揮藍(lán)牙通信的優(yōu)勢(shì)而解決環(huán)境惡劣情況下的諸多不便。因此,近年來(lái)越來(lái)越多的藍(lán)。目前,嵌入式系統(tǒng)芯片眾多,主要有51系列、ARM系列及DSP系列。后兩者現(xiàn)在越來(lái)越有取代前者。新華龍公司出產(chǎn)的C8051F020是C51系列片子中用得比較廣的一款,此芯片主要。實(shí)現(xiàn)的SPI、SMBus/I2C和兩個(gè)UART串行接口;5個(gè)通用的16位定時(shí)器;片內(nèi)看門狗定時(shí)器、VDD監(jiān)視。藍(lán)牙部分)組成,如圖1所示。同時(shí)采用MAX8881芯片將。電流,電池在使用的同時(shí)仍然會(huì)被充電。為了增強(qiáng)設(shè)備的電源抗干擾能力,設(shè)計(jì)時(shí)在每級(jí)電源的前后級(jí)。最小粒子檢出水平,調(diào)整電阻值可調(diào)整Vout1的靈敏度。UART口驅(qū)動(dòng)程序主要包含C8051F020微處理器的串口初始化、藍(lán)牙通信參數(shù)設(shè)
【正文】 th in reality Connect) initialization, bluetooth munication parameter setting, HCI instruction encapsulation, number According to information processing parts, main functions described below: (1) a serial port initialization function, main set the serial port Rate for 38,400 BPS, data format for a starting position, eight data A, one stop bits, and makes the corresponding processing in serial。 (2) bluetooth data parameter setting function, the function mainly pletes Bluetooth module initialization and the bluetooth data format of packing。 (3) data information processing function, the function mainly realizes bluetooth Initialize 8 return data processing, by judging these returned letter Interest to determine the state of bluetooth module。 (4) serial reading and writing data function, the function is a serial port to send and receiving data realization. The dust detector software flowchart of shows, dust detector by ordinary IO mouth and CPU for data exchange. Relevant software code for Voidmain () { Init uart ()。 / / initialization uart interface, drive bluetooth module Init device ()。 / / initialization dust detector, periodic acquisition Equipment parameters Time AP Receive ()。 / / receiving the number from bluetooth access point According to and updates the instructions Time device ()。 / / gain.

The equipment according to the practical demands can also for bluetooth module for with serial interface for ZigBee modules and b model block, realize the other industrial monitoring field dust test equipment of hardware asher meter. Therefore, the realization of the design in family automation (work appliances, family all kinds of electric control), intelligent building and building control, industrial presently field equipment monitoring etc realize munication has certain application value.
