[Linux][SSH] Sự khác nhau giữa authorized_keys và known

[Linux][SSH] Sự khác nhau giữa authorized_keys và known_hosts file trong thư mục ~/.ssh

2 file này xuất hiện khi máy ubuntu của bạn vừa là server vừa là client
known_hosts
Khi máy của bạn là client, known_hosts sẽ lưu lại public key của những server(host) bạn đã truy cập trước đó.

authorized_keys
Khi máy của bạn là server, authorized_keys lưu lại public key của những client đã kết nối đến máy của bạn trước đó.

[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 −...
