該步進(jìn)電機驅(qū)動器又稱為EasyDriver，EasyDriver能夠為兩級步進(jìn)電機提供大約每相750mA（兩極一共1.5A）的驅(qū)動。它默認(rèn)設(shè)置為8步細(xì)分模式（所以如果你的電機是每圈200步，你使用EasyDriver時默認(rèn)為每圈1600步），更多細(xì)分模式可以通過將MS1或MS2兩個接腳接地進(jìn)行設(shè)置。這是一種基于Allegro A3967驅(qū)動芯片的細(xì)分?jǐn)嗦菲鳌τ诖嗽O(shè)計的完整規(guī)格，請查閱A3967的參數(shù)表。它的最大每相電流從150mA到750mA。可以采用的最大驅(qū)動電壓大概是30V，其中包括板載5V的調(diào)壓器，所以只需要一個電源。質(zhì)優(yōu)價廉，這玩意兒只要十幾美元，比你自己制作電路板更便宜。步進(jìn)電機驅(qū)動器設(shè)計特色：· A3967 Microstepping Driver· MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)· Compatible with 4, 6, and 8 wire stepper motors of any voltage· Adjustable current control from 150mA/phase to 700mA/phase· Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds

程序功能說明：1、通過STM32的硬件I2C讀寫控制BH1750光照度傳感器模塊測量環(huán)境光照強度。2、程序通過串口打印輸出光照強度值。3、程序?qū)⒐庹諒姸戎翟贚CD屏上顯示。程序注意事項：1、根據(jù)BH1750傳感器手冊可知，在One Time H-resolution Mode2測量模式下測量光照強度大于會要120ms以上的測量時間，所以程序在發(fā)送測量命令以后應(yīng)該盡量延時120ms以上，否則測量出來的數(shù)據(jù)不準(zhǔn)確。2、在兩次測量之間最好加個延時，也就是在第一次測量結(jié)束和下次測量命令發(fā)出之間加個100ms左右的延時，否則也會出現(xiàn)測量錯誤的問題。3、在使用FSMC驅(qū)動LCD時不能用I2C1，只能用I2C2，或者將I2C1的時鐘和引腳重映射。4、測量結(jié)果保存在兩個字節(jié)中的，所以需要作移位處理，具體處理方式可以產(chǎn)考手冊和程序。

Simulation can provide a lot of information about what the system is doing. We canadd the effect of different element, like Encoder resolution, ADC sampling rate, etc and understand how does it affect the system. Another benefit is the possibility to slow down the process, to gain insight on what happens of fast systems or, vice versa, speed up slow process.Because National Instruments is a unique company in the fact the we provide a fullhardware solution couple with a full development platform, we can use this tools in very particular ways For example, it is possible to combine the LabVIEW Control Design and Simulation Module along with the FPGA module to quickly prototype a controller. One of the main benefits of this approach is that there is no need to compile the FPGA code, which allows for a quick algorithm design turnaround and debugging.
