1
Hi everyone, welcome to the WiiW Electronics.
2
So this tutorial is about the programming the STM32F1 microcontroller
3
and this video is an introduction to the tools we will be using during the whole tutorial.
4
So this is more for beginners
5
or hobbyist who would like to get more knowledge about microcontroller in general and also especially the STM32F1 microcontroller series.
6
There will be some discussion about the ARM microprocessor but not something in depth.
7
Before continuing, one of the recommendation is to use a PC screen to
8
watch these videos as I will be taping directly in the IDE.
9
Two screens would be best so you would be watching one screen and testing by yourself and the other one.
10
So this also tutorial will be making all the code from scratch
11
and the C level language
12
that will be used will be in introduction to an intermediary level so it will not be hard to understand.
13
So during this series the tool
14
that will be used from a software perspective for the first thing
15
and the most important one we will be using the KL5.
16
Let me IDE is made by the ARM company themselves.
17
Most of the microcontrollers have a huge library with
18
microcontrollers having the ARM microprocessor so that's quite a good one
19
and also even you don't have the hardware there is a quite simulation option
20
that you can use so you can simulate how your microcontroller will be behaving to a certain extent.
21
We will be showing some simulation so we can understand the behavior before even uploading the code in our microcontroller.
22
I made a series for the Kale in a different tutorial where I showed how to create a project
23
and also how to open the debug mode
24
so feel free to take a look at it as for the next videos
25
I will skip this part just for saving time and focusing on the core topic of that video
26
Also the other software I'll be using is the STM32CubeMX which is STM software.
27
I will not use this software to generate code
28
but mostly to show because it has a good graphic explanation for each microcontroller
29
and it helps to get quickly the information of the data for the microcontroller.
30
This is for the softwares I may use other one
31
but it will be quite introduced for different videos okay
32
and now for the hardware for the hardware I'll be using this blue board aka blue pill
33
so this blue board have the microcontroller the STM F103 C3
34
microcontroller one board would cost around two to three boxes I bought three four five boxes
35
and they can not soldered with the pin
36
so I soldered in a different way
37
and to program these microcontrollers there is this ST
38
and link V2 careful they are not genuine programmer
39
but they can work if it happens to you
40
that you buy the pink one just I would like to give you a short warning I took a picture
41
so I can give you what would be the issue
42
so as you can see here this is the USB picture showing
43
that the pin number 2 is the clock
44
and the pin number 4 is a DIO however
45
if you open the PCP you will see
46
that pin number two is the deio
47
and the pin number four is the clock one so be careful
48
when you do the wiring the pcb is the correct one
49
and if you do according to what the usb is showing you would may have an issue
50
and you will not be able to program your microcontroller okay good this is said
51
so this is about the hardware that will be used for the document
52
that I will be using and this document will be used just to explain to you
53
and to show you how to to program even a different microcontroller the first one will be the datasheet
54
So the datasheet for the one who are introduced are a summary of the microcontroller.
55
So as I told you I'm using the STM32F103 series
56
and it shows here the main features that we will be using in our programming videos.
57
The first one is a microcontroller that can go to 72 MHz of maximum frequency which is pretty good.
58
We will see what kind of speed we will go with that.
59
It has also 64 KB of memory, so this is the flash memory for the program, and 20 KB of SRAM.
60
It's a 3 .6 volt microcontroller but that should be fine for our application.
61
It has also an analog to digital converter.
62
We will have a video about it.
63
A DMA also.
64
The microcontroller we will be using have 48 pins, not 80, but it has 16 interrupt factors
65
which is quite great to use a lot of applications to have real -time system.
66
One of the great things too, it's a 5 volt tolerant.
67
So if it happens we use a different connection connection that have 5 volts we are not risking to destroying our microcontroller.
68
Yeah and also it has a debug mode.
69
We will be using a lot the CAIL to debug
70
and to see how our program is interacting which is really great for beginners to understand where the issue is.
71
There is timers and each timer have four channels will can be programmed in different way
72
and for the communication interfaces we will take a look to the I2C, the UART and the SPI.
73
So that's a general picture.
74
I quite advise you to take a look to this document it's quite short one only 117 pages
75
and the final document that we will be using will be the reference
76
Street this one and this document have 1133 page it's quite impressive
77
but this is the kind of like the guy
78
that you hate from the first sight
79
and with time it becomes your best friend
80
so we will use this document to a lot to do the programming
81
it has almost all the answers quite a good one
82
so let's see how we will how we finish it okay
83
so thank you a lot for this video and see you for the next one thanks

影片中的語法

說話人最常用的結構,並附上影片中的原話:

結構影片中的用法
被動語態 be + 過去分詞 — 強調發生了什麼,而不是誰做的is made · is said · are introduced
定語從句 who / which + 從句 — 補充說明人或事物one who are · frequency which is · interacting which is

需要注意的發音

說話人用了 4 次縮略和弱讀形式,例如 I'll, don't, I'm。請按聽到的簡短形式來說。

  • “sh” 和 “zh” 音: simulation /ˌsɪm.jəˈleɪ.ʃn̩/, flash /flæʃ/, explanation /ˌɛkspləˈneɪʃən/, recommendation /ˌɹɛkəmɛnˈdeɪʃən/

  • 詞尾子音 — 要讀清楚,後面不要加母音: clock /klɑk/, introduce /ˌɪntɹəˈdus/, topic /ˈtɑpɪk/, extent /ɪkˈstɛnt/, impressive /ɪmˈpɹɛsɪv/
  • /r/ 和 /l/ 的區別: tutorial /ˌtjuːˈtɔːɹɪəl/, tolerant /ˈtɑːləɹənt/, microcontroller /ˈmaɪkɹoʊkənˌtɹoʊlɚ/, solder /ˈsɒl.də(ɹ)/

如何用這段影片練習

  1. 先完整聽一遍影片,不要開口,記下不認識的單詞。
  2. 用正常速度逐句跟讀,每句重複到你的節奏與說話人一致為止。
  3. 錄下自己的聲音並與原聲對比,特別注意 hardware, tutorial, introduce 這類單詞。

什麼是跟讀法?

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧,最初開發用於專業口譯員的培訓,並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大:您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同,跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性,語調,節奏,連讀,聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
