Avoid processed foods, sugary drinks, and excessive amounts of saturated and trans fats, which can increase the risk of chronic health conditions such as heart disease and diabetes.

  3. Get enough sleep: Getting enough sleep is essential for overall health and well-being. Aim for 7-9 hours of sleep per night to ensure that your body has enough time to repair and rejuvenate itself. Lack of sleep can lead to a number of health problems, including fatigue, mood swings, and an increased risk of chronic conditions such as obesity, diabetes, and heart disease.

  4. Manage stress: Stress is a normal part of life, but chronic stress can have a negative impact on our health. Practice stress-management techniques such as meditation, yoga, or deep breathing to help reduce stress levels and improve overall well-being.

  5. Get routine check-ups: Regular check-ups with your healthcare provider can help identify and prevent potential health problems. These check-ups are a great opportunity to discuss any concerns you may have, get vital signs checked, and receive any necessary screenings.

  6. Stay up to date with recommended screenings: Regular screenings can help identify potential health problems early, when they are most treatable. This can include mammograms, colon cancer screenings, and blood pressure checks.

  7. Don't smoke and limit alcohol: Smoking and excessive alcohol consumption can increase your risk of chronic health conditions such as lung cancer, heart disease, and liver disease. It's important to quit smoking and limit alcohol consumption as much as possible.

  8. Stay socially active: Maintaining social connections can help improve mental and emotional well-being. Engaging with friends, family, and community can provide emotional support, reduce feelings of isolation, and improve overall mood.

  9. Stay mentally active: Keeping your mind active can help prevent cognitive decline and maintain cognitive function. This can include activities like reading, doing puzzles, or learning new skills.

  10. Stay informed about your health: Stay informed about your health and any conditions you may have, and be proactive in managing them. This can include working with your healthcare provider to create a personalized health plan and staying up-to-date on any new treatments or therapies that may be available.



In conclusion, taking care of your health during middle age is crucial for maintaining overall well-being and preventing chronic health conditions. Regular exercise, a healthy diet, and enough sleep are essential for maintaining physical health, while stress management and social connections can help maintain mental and emotional well-being. It's also important to stay up-to-date with recommended screenings, stay informed about your health and any conditions you may have, and work with your healthcare provider to create a personalized health plan. Remember, the earlier a health problem is identified and treated, the more likely it is that it can be effectively managed or even prevented.

아두이노 프로그램의 volatile 지시자

 지시자(directive)인 volatile 은 변수 선언문의 변수형 앞에 두어서 컴파일러가 그 변수를 접근하는 방식을 지정한다.

 일반적으로 변수 데이터는 런타임에 RAM영역에 저장되지만 어떤 변수는 레지스터(register)에 임시로 저장되어 사용하기도 하는데 이 경우 속도면에서는 월씬 유리하지만 RAM에 저장된 실제 데이터와 레지스터에 저장된 (임시)데이터가 서로 다른 경우가 발생할 수도 있다.

 어떤 변수를 volatile로 지정하면 그 변수 데이터는 레지스터의 임시 저장소가 아니라 RAM에서 직접 읽어오도록 컴파일된다. 아두이노 프로그램의 경우 보통은 volatile로 정의할 필요는 없으나 인터럽트 서비스 루틴 (ISR) 내부에서 그 값이 변경되는 변수는 반드시 volatile로 선언해야 실시간으로 변경되는 데이터 값을 ISR 외부에서 정확하게 읽어올 수 있게 된다. 예를 들면 다음과 같다.

// toggles LED when interrupt pin changes state

int pin = 13;
volatile int state = LOW;

void setup()
{
 pinMode(pin, OUTPUT);
 attachInterrupt(0, blink, CHANGE);
}

void loop()
{
 digitalWrite(pin, state);
}

void blink()
{
 state = !state;
}

위의 예에서 blink()함수가 ISR이며 이 안에서 변경되는 변수 state는 volatile로 지정하였음을 확인할 수 있다.

파이썬의 smbus 패키지를 이용하여 i2c 통신하기

 며칠간 라즈베리파이와 아두이노간 i2c 통신을 위해서 python3-smbus 라이브러리를 사용하였는데 여기에 몇 가지를 기록한다. 설치하는 법은 다음과 같다.

sudo apt-get update (먼저 반드시 수행해야 한다.)
sudo apt-get install python3-smbus

라즈베리파이 B+와 ver. 2 에는 i2c 포트가 두 개가 있는데 각각 i2c-0, i2c-1 이다. 만약 1번을 사용한다면 다음과 같이 초기화 할 수 있다.

import smbus
dev = smbus.SMBus(1)

smbus 레퍼런스에 보면 cmd (command) 파라메터가 있는데 이것은 단순히 보내는 데이터의 맨 앞에 먼저 보내지는 데이터이다. 보통 슬레이브는 이것을 보고 어떤 명령인지(또는 어떤 데이터가 따르는지)를 판별한다.

 그리고 함수들 중에 i2c 가 붙은 것들이 있는데 이것이 더 효율적이라고 한다.

read_i2c_block_data(addr, cmd [, length] )
write_i2c_block_data(addr, cmd, lst)

write_2ic_block_data()함수는 다음과 같이 데이터를 전송한다.

cmd
lst[0]
lst[1]
...
lst[-1]

read_2ic_block_data()함수는 cmd 한 바이트를 먼저 전송한 후 데이터를 읽어온다.

smbus에는 write_block_data()라는 함수도 있는데 write_i2c_block_data()와의 차이점은 전송되는 데이터가 하나 다르다는 것이다. 두 번째 바이트에 데이터의 길이를 전송한다.


cmd
size
lst[0]
lst[1]
...
lst[-1]

만약 i2c 통신을 사용하는 것이라면 read_i2c_block_data(), write_i2c_block_data() 함수를 사용하는 것이 좋다.
