Core needed skills for embedded system engineer

  There are three main skills you need to get your hands dirty to become a master in this field: Soldering, Programming, and Electrical Prototyping 1. Core Skill: Soldering This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools. 1   Noob Noob  - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need. 2   Rookie Rookie  - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux. 3   Competent Competent  - You will encounter surface mount components and basic SMD soldering techniques are required. 4   Experienced Experienced  - You might be required to do some reflow or basic rework with SMD components. A heat gun, Heaterizer or o

[Basic] C program and SRAM, flash, stack, heap ... Why microcontrollers use different types of memory like that?

Preface When you build the source code in C/C++, you might see some output messages as the blow: Flash used: 1166 of 262144 bytes (0.4%). SRAM used: 2505 of 65536 bytes (3.8%). Stack: 2048 bytes. Heap: 128 bytes. --------------- Rebuild Succeeded: 10/01/2024 17:46:40 --------------- Figure 1: The output message from PSoC Creator Figure 2: The output message from Arduino IDE Have you asked yourself what are technical jargon such as flash, stack, and heap? In short, they are kinds of memory for machines. Microcontrollers use different types of memory (Flash, SRAM, EEPROM, etc.) because each type serves a specific purpose, balancing factors like cost, speed, power consumption, and data persistence . Key Differences Between These Memory Types: The explanation for the output message in the figure 1: Flash used : 1222 of 262144 bytes (0.5%) The program's code occupies 1222 bytes of the total available 262144 bytes in Flash memory. This is a very small portion, showing efficient memory us

[C++] Apply the primary principle of C++ for preparing a meal

  Let's apply the principle of C++ (object-based programming) to the task of preparing a meal. In object-based programming, we break down tasks into objects that represent real-world entities. These objects have attributes (data) and methods (actions they can perform). Example: Preparing a Meal in C++ Style Imagine you're preparing a meal with different objects, each responsible for a specific part of the process. For simplicity, let's define three main objects: Chef , Ingredients , and KitchenTools . 1. Chef Object : Attributes : Name, experience level. Methods : prepareMeal() , useTool() , mixIngredients() . 2. Ingredients Object : Attributes : Type (vegetables, meat, spices), quantity, freshness. Methods : chop() , cook() , serve() . 3. KitchenTools Object : Attributes : Tool type (knife, pan, oven), condition (new, used). Methods : cut() , heat() , stir() . C++-Style Meal Preparation Example: Here’s how we would code a meal preparation process in C++: Breakdown: The

[MiniProject] Convert Vietnamese unicode strings to unaccented strings

 Recently, I embarked on an exciting Arduino project where I needed to convert Vietnamese Unicode strings into their unaccented equivalents. The goal was simple, but I quickly ran into a problem: the conversion process wasn’t working as expected. Characters like "Độc lập tự do" were returning as a string of question marks! I reached out for help and discovered that the issue was rooted in the way UTF-8 encoding was handled in my code. With some guidance, I learned how to properly decode UTF-8 characters into their Unicode equivalents before converting them. By breaking down the string into manageable arrays and thoroughly testing each case, I finally got the correct output: "Doc lap tu do." This project taught me the importance of understanding encoding and the value of community support in problem-solving. Now, my Arduino project runs smoothly, converting Vietnamese text as intended! The serial Monitor output: Unicode & Vietnamese Legacy Character Encodings htt

[Vi] Công nghệ phát triển ngược đời - How is AI harming my world

Tiếng cười khanh khách của mấy cậu sinh viên quốc tế người Bắc Ấn sau bài kiểm tra cuối khóa (a final exam) làm gã thấy buồn một góc tâm hồn. Sự trống rỗng ngay lập tức xâm chiếm lấy tâm trí gã sau khi nộp bài môn thi cuối cùng của kỳ học. Gã hiểu gã quá mà, gã đang cố gắng giải thích cho nỗi nhục của chính bản thân ở bên trong. Đầu gã thoáng nghĩ về cái lần thi cuối kỳ một môn học ở bậc thạc sỹ nơi quê nhà hơn mười năm về trước, cái ánh mắt khinh bỉ đến ám ảnh của một anh dọn vệ sinh dành cho những học viên cao học đang quay cóp trong giờ thi của một trường đại học hàng đầu quốc gia như vết dao khứa vào lòng tự trọng của gã. Vết thương vẫn nhói đau lại khi những mùa thi đến. Một lão già sinh viên quốc tế ranh ma. Gã đang học lại cái thứ mà gã đã học từ hai mươi năm về trước với một thứ ngôn ngữ không mới và cái tâm bằng sắt nung. Kinh nghiệm làm việc chuyên môn lâu năm cộng với việc vừa được trang bị thứ vũ khí khoa học tối tân AI (Trí truệ nhân tạo) khiến lão trở thành sát thủ trong

[MyThought] Software design scalability, how to navigate conflicting perspectives

 Your team disagrees on software design scalability. How do you navigate conflicting perspectives? First of all, disagreements usually come from different viewpoints and personal biases. When people look at a problem, they each see it from their own perspective. To make sure everyone’s on the same page, it helps to list out the main issues before jumping into brainstorming. Remember, how scalable the software is will depend on both the project’s budget and timeline. Secondly, based on the project's budget and timeline, team members are encouraged to share their thoughts freely during the brainstorming session. Afterward, we'll gather the most outstanding ideas and compile them into a table of options. We'll then weigh these options based on several criteria, and finally, we'll select the top-ranked one. Moreover, I work in the field of embedded software. Whenever we design a new product, we must consider both the hardware and software aspects. Hardware is always the fir
