Exciting update! 🚀 Excited to share that I've completed a Full Layered AUTOSAR Project with the TM4C123GH6PM Micro-controller "ARM architecture" under the supervision of Eng. Mohamed Tarek at Edges For Training. Navigating through intricate requirements, such as precise button press/release timings and LED output refresh rates, was a thrilling challenge. Here's an overview of the project's architecture: 🔹 MCAL: Developed DIO, GPT, and Port AUTOSAR drivers. 🔹 ECUAL: Implemented LED and Button drivers (LED connected to PF1, button to PF4). 🔹 Service Layer: Implemented an efficient scheduler alongside Development Error drivers. 🔹 Application Layer: Executed flawless system logic design. Notably, the scheduler monitors the button state every 20ms, detecting press/release events if held low/high for 60ms, and ensures LED output refresh every 40ms.

Excited to share my latest Embedded System project developed during the University Embedded Systems Course under Prof. Haitham El-Hussieny's guidance! Using an ATmega32 microcontroller, ULN2003 driver, and a bipolar stepper motor, I developed a system that offers precise control over motor rotation. The system allows users to select rotation direction (clockwise or counterclockwise) and step mode (half-step or full-step) through external switches, enhancing versatility for various applications. The heart of the project lies in the C programming, where interrupt service routines (ISRs) handle external interrupts triggered by the switches. Based on the switch states, the microcontroller executes specific functions to control motor rotation, providing accurate movement. What sets this project apart is the addition of an LCD display that shows the degree of motor rotation in real-time, aligned with the lighting of the LED corresponding to the mode of rotation, offering users valuable feedback on the motor's status and position. This project not only showcases my skills in embedded systems and microcontroller programming but also demonstrates my ability to integrate multiple hardware components to create a functional and versatile control system. A huge thanks to Prof. Haitham El-Hussieny for his invaluable guidance and support throughout this course journey! #EmbeddedSystems #Microcontroller #StepperMotor #DIYProjects #ATmega32 #Engineering

🔻🔻🔻🔻🔻🔻🇵🇸#Gaza_Genocide🇵🇸 🔻🔻🔻🔻🔻🔻 #شمال_غزة_يموت_جوعاً ‏#Famine_in_North_Gaza One of the important comparisons that I made to clear the doubt for EMC Engineers about Power factor definition and the relation between Power factor and Harmonics Current distortion. I carry out the analysis on two case studies with approximately the same value of power factor. The first case is a device with a variable speed driver circuit (VSD) which has a PF=0.538 and the second case is a device with Inductive load which has a PF= 0.618 The two values of Power factor are very close and from the first time you will think that you will get a similar results of THD(%) or harmonics current but in the fact there is a big difference between the two cases (the second case is more better than the first one even if they have the same value of Power factor). This can lead us to understand that the Harmonics Current or the THD doesn't depend on the value of the power factor only but it mainly depends on the value of the current at the fundamental frequency (I fund.) compared with the value of RMS input current. From the Equation (PF= True power /apparent power). 🔴#True_power = Irms(active current) * Vrms *Cos(¢) ⚫#Apparent_Power = Irms(input)*Vrms 🟢#Case_Study_1_VSD_Load The two waveforms I&V are in phase (zero phase shift) this doesn't mean that PF = COS (¢) =1 because it's not a linear resistive load, So PF = Irms(Fundamental current) * Vrms *Cos(¢)/Irms(input)*Vrms, then PF= I_fund./Irms = 0.538. Regarding to the value of #PF you will see I_fund is approximately 50% of Irms(total) this means that there is a 50 % of the total current are used and the other 50% will be lost in Harmonics current and lead to a very high total Harmonic Distortion THD & THC (THD=125%).This case isn't conformed with IEC 61000-3-2 limit (Very high Harmonics current "Not_Good_Design"). 🟢#Case_Study_2_Inductive_Load The voltage is leading the current and the two waveforms I&V are phase shifted by approximately (50°), So PF = Irms(Fundamental current) * Vrms *Cos(¢)/Irms(input)*Vrms then PF= I_Fund. * COS (50)/Irms(Total) = 0.618 Regarding to the value of #PF you will see I_fund is very close to Irms(total) this means that all the current is used and active by the load and there is a very small values of Harmonics current and a little THD but the power factor is low because it depends on the phase shift between I&V not the value of the Harmonics current. This case is conformed with IEC 61000-3-2 limit (Very low Harmonics current "Good_Design"). This is the big difference between #Case_1 (VSD Non_Linear Load) and #Case_2 (Linear Inductive Load) even if they have the same power factor. 🔻🔻🔻🔻🔻🔻🇵🇸#Gaza_Genocide🇵🇸 🔻🔻🔻🔻🔻🔻 🇵🇸#Power_Factor 🇵🇸#THD 🇵🇸#Harmonics_distortion

𝐁𝐚𝐭𝐭𝐞𝐫𝐲 𝐌𝐚𝐧𝐚𝐠𝐞𝐦𝐞𝐧𝐭 𝐒𝐲𝐬𝐭𝐞𝐦 : 𝐋𝐞𝐚𝐫𝐧 𝐀𝐥𝐥 𝐲𝐨𝐮 𝐍𝐞𝐞𝐝 𝐓𝐨 𝐊𝐧𝐨𝐰 𝐀𝐛𝐨𝐮𝐭 (𝐋𝐚𝐭𝐞𝐬𝐭 𝐈𝐧𝐟𝐨𝐫𝐦𝐚𝐭𝐢𝐨𝐧) A battery management system (BMS) is a technology which is designed to monitor the performance of a battery pack. It is an electronic installed in equipments & machines that controls and monitors charging and discharging of the batteries and provides updated about the status and condition of battery packs. In addition, the BMS provides critical safeguards to protect batteries from damage is one of the primary functions of battery management system. The design of lithium-ion battery has two critical design issues which includes overcharging and overheating, flames. In addition, the li-ion battery may be damaged if discharged below a certain threshold, which is around 5% of the total capacity. Factors such as accelerated adoption of electric vehicles (EVs) and hybrid electric vehicles (HEVs) and A surge in industry preference toward the utilization of lithium-ion batteries drives growth of the battery management system market. In addition, growth in adoption of rechargeable batteries across multiple end-use industries propels the market growth. However, rise in overall price of products with addition of battery management system hinders growth of the market. Further, increase in adoption of cloud-connected battery management systems, growth in demand for renewable energy, and rise in demand for e-bikes and e-scooters provide remarkable growth opportunities for players operating in the market. The battery management system is segmented into battery type, topology, application, and region. On the basis of battery type, the market is categorized into lithium-ion based, lead-acid based, nickel-based, and others. On the basis of topology, it is segregated into centralized, distributed, and modular. The global battery management system market size was valued at $7.5 billion in 2022, and is projected to reach $41 billion by 2032, growing at a CAGR of 19.1% from 2023 to 2032.

🔻🔻🔻🔻🔻🔻🇵🇸#Gaza_Genocide🇵🇸🔻🔻🔻🔻🔻🔻 Today I had an important case study that I've never seen before and I want to share my analysis with your because it gave me a crazy feeling when determining whether it will pass or fail the standard limitations for a product with a DC-DC converter. After the first scan with the peak detector I saw that the signal level was above the average limit and below the quasi-peak limit at around 160 kHz and other frequencies. I selected the points that exceeded the average limit and re-evaluated the final result again using Quasi-peak limit, I noticed that the Quasi-peak value of RF signal at 160KHz is greater than the peak value at the same frequency. Someone can ask a question what is happened??🤔 🤔 Let me describe this case briefly, DC-DC converter circuit has a very high frequent switching operation with a pulse of 60KHz and as we know that the first scan using peak detector has a little scanning time compared with Quasi-peak detector so in the peak search the time is not enough to get the highest peak level due to high frequent switching operation but in Quasi-peak detector the time is large and enough to pick up different levels of RF signal at the same frequency that enables to see number of frequent switching operation, so we see that the Quasi-peak value is greater than the peak value at the same frequency. 🔻🔻🔻🔻🔻🔻🇵🇸#Gaza_Genocide🇵🇸🔻🔻🔻🔻🔻🔻 #EMI #Standard_Limitation #Quasi_Peak_Vs_Peak
