Differences Between Parameters and Arguments

Sự khác nhau giữa Parameter và Arguments

Wiki said:

The terms parameter and argument are sometimes loosely used interchangeably, and the context is used to distinguish the meaning. The term parameter (sometimes called formal parameter) is often used to refer to the variable as found in the function definition, while argument (sometimes called actual parameter) refers to the actual input passed. For example, if one defines a function as def f(x): ..., then x is the parameter, while if it called by a = ...; f(a) then a is the argument.

Basic concept:

argument is actual parameter
parameter is formal parameter

Example:

Ta có prototype của 1 hàm: void Func(int x)
Thì x ở đây gọi là parameter
Trong chương trình ta gọi hàm Func(10). Thì 10 ở đây chính là argument

[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 ...
