STICKIES Note everything what you want :D
Phần mềm này hỗ trợ việc take note trên PC. Rất đơn giản, bạn chỉ cần copy 1 đoạn text, hoặc 1 cái picture, ở đâu đó, rồi ấn tổ hợp phím Ctrl + Alt + S. Thế là bạn có 1 cái note mới. Tất nhiên, còn 1 số tính năng khá hay khác nữa, các bạn tự khám phá nhé. (Ví dụ như backup lại cấu hình đã thiết lập, chia sẻ note cho bạn bè....)
1. Take note from clipboard
Step1: Ctrl + C your clipboard (like as picture, text, whatever...)
Step2: By default, create new stickies from your clipboard by press Ctrl + Alt + S 
For example:
Clipboard is picture
Clipboard is text
2. Other functions (back-up, sharing, retore configuration)
You can set up many other function by press right mouse in Stickies Icon what is always placed on task bar

Web hỗ trợ những thao tác tính toán bít, chuyển đổi giữa các đơn vị đo
Ví dụ: Thao tác dịch bít (Bit shift)

1. C/C++ short paragraph
a. How to convert from byte array to float number?
(Cách chuyển 1 mảng byte thành 1 số float)
Assume, you have 4 bytes array like that:
[0x0] 0x67 'g' unsigned char
[0x1] 0xab '«' unsigned char
[0x2] 0xa7 '§' unsigned char
[0x3] 0x41 'A' unsigned char
and you want convert them to float number. This is simple solution:
typedef union test
02{
03   unsigned char buf[4];
04   float number;
05}test;
06
07test.buf[0] = 0x67;
08test.buf[1] = 0xAB;
09test.buf[2] = 0xA7;
10test.buf[3] = 0x41;
11
12printf("%f\n",test.number);
Result is: 20.958693

[STM32] How to configure Timer 1, Channel 3 is PWM 1kHz, duty cycle 20% to control BLDC motor

 To configure Timer1 for a 1 kHz PWM signal with a 20% duty cycle on an STM32H7S3L8 microcontroller, follow these steps: 1. Understand the Timer Parameters PWM Frequency : 1 kHz → Period = 1 ms. Duty Cycle : 20% → ON time = 0.2 ms. The timer’s clock frequency is derived from the APB clock (e.g., TIMCLK). Let’s assume you know the APB clock frequency. The Timer prescaler and auto-reload register (ARR) define the PWM frequency. 2. Compute Timer Parameters Formula: PWM Frequency = Timer Clock (Prescaler + 1) * (ARR + 1) \text{PWM Frequency} = \frac{\text{Timer Clock}}{\text{(Prescaler + 1) * (ARR + 1)}} PWM Frequency = (Prescaler + 1) * (ARR + 1) Timer Clock ​ For 1 kHz PWM: A R R = Timer Clock PWM Frequency ∗ ( Prescaler + 1) − 1 ARR = \frac{\text{Timer Clock}}{\text{PWM Frequency} * (\text{Prescaler + 1)}} - 1 A RR = PWM Frequency ∗ ( Prescaler + 1) Timer Clock ​ −...

[Git] Handle trailing space when patching with git

After complete coding one module in development branch. Next phase is merging. Obviously, you can merge source code automatically without no errors happen. However, life is not dream. Create a patch git diff HEAD > newTariff.patch Apply patch git apply newTariff.patch then problem happens Problem git apply newTariff.patch:106: trailing whitespace. patch does not apply Route cause: Nguyên nhân: Do trong source code có những dấu space thừa (ô vuông màu đỏ hình dưới) Some whitespaces is existed in your patch. (red area in below pictures) Fix Clean white space and patch again. Cách khắc phục Xóa những dấu space này đi và thực hiện patch lại Make up after complete coding. Find and clean whitespace before create patch file. Sửa sau khi code xong Kiểm tra sau khi code xong có lỗi này không git diff HEAD --check Prevent whitespace by manually when typing source code Sửa ngay khi đang code =>Bật chức năng hiển thị các dấu whitespace, hoặc remove trailing ...
