揭開(kāi)STM32F446 NUCLEO-144的神秘面紗,外觀測(cè)評(píng)及資料分享

首先上板子的照片
 
板子正面可以看到,前端的小板是STLINK的芯片是F103。有了它就可以省去下載線,用安卓手機(jī)的數(shù)據(jù)線就可以調(diào)試和下載程序,非常方便。目前我也在做一個(gè)STM32相關(guān)的設(shè)計(jì),也想把這個(gè)加進(jìn)去。然后來(lái)看主板部分,中間一個(gè)主芯片地方是排母,按鍵,mircousb,LDO阻容等,外設(shè)網(wǎng)口空著沒(méi)有焊接。排母周圍的絲印標(biāo)這個(gè)這些IO的功能,比較方便去找相應(yīng)的位置。
 
我們?cè)賮?lái)看看后面,這次的排座是長(zhǎng)插針形式的,就是后面還可以當(dāng)插針用,直接插杜邦線,上面是排母,下面是針的形式也是比較貼心的,這樣你可以做個(gè)轉(zhuǎn)接板插在上面,也可以插在下面,也可以直接用線在下面引出去,開(kāi)發(fā)調(diào)試的時(shí)候還是挺方便的。還有就是這次的板子支撐是四個(gè)角的跳線帽,雖然覺(jué)得有點(diǎn)簡(jiǎn)單,但是感覺(jué)應(yīng)該還是用用處的,在板子接外面的電路時(shí)候,地往往都要用很多,這個(gè)跳線帽的網(wǎng)絡(luò)就是地,一舉兩得。

然后在看看開(kāi)發(fā)板配套的資源吧,由于本人水平有限,可能理解的不夠透徹,還請(qǐng)各位高手多包涵哈!

先把基本的手冊(cè)傳上來(lái)讓大家一起看看吧,包括芯片的datasheet,參考手冊(cè),編程手冊(cè),開(kāi)發(fā)板的手冊(cè),原理圖,gerber,BOM,還有一個(gè)以前一直沒(méi)怎么注意,才發(fā)現(xiàn)的一個(gè)非常厲害的工具,在用的就忽略這段吧。那就是stm32cubemx這個(gè)軟件。
看看它的介紹:
STM32CubeMX is a graphical tool for 32-bit ARM? Cortex? STM32 microcontrollers. It is part of STMCube? initiative (see Section 1) and is available either as a standalone application or as an Eclipse plug-in for integration in Integrated Development Environments (IDEs).
STM32CubeMX has the following key features:
· Easy microcontroller selection covering whole STM32 portfolio.
· Board selection from a list of STMicroelectronics boards.
· Easy microcontroller configuration (pins, clock tree, peripherals, middleware) and
generation of the corresponding initialization C code.
· Easy switching to another microcontroller belonging to the same series by
importing a previously-saved configuration to a new MCU project.
· Generation of configuration reports.
· Generation of IDE ready projects for a selection of integrated development
environment tool chains. STM32CubeMX projects include the generated initialization C
code, STM32 HAL drivers, the middleware stacks required for the user configuration,
and all the relevant files needed to open and build the project in the selected IDE.
· Power consumption calculation for a user-defined application sequence.
· Self-updates allowing the user to keep the STM32CubeMX up-to-date.
· Download and update of STM32Cube? embedded software required for user
application development (see Appendix E: STM32Cube embedded software packages
for details on STM32Cube embedded software offer).
Although STM32CubeMX offers a user interface and generates a C code compliant with STM32 MCU design and firmware solutions, it is recommended to refer to the product technical documentation for details on actual implementation of microcontroller peripherals and firmware.
