Felix Chen Email & Phone Number

I am the person enjoy challenges and taking new tasks. I do believe that life only comes once, and ifyou don’t take the opportunity to explore when you're young, chances will diminish as you get older.Therefore, it's important to seize the moment, and even if you don't succeed, you won't feel regrets.I enjoy researching new things and making small projects, such as models or small devices. Andlike to browse through newly published technical books during my free time. Cause people can grow and surpass oneself by self-learning and this is how/why I value the important of myself-learning. On theother hand, I also believe that technology inheritance and documentation are important, so I havespent lots of time writing technical articles on my personal blog and sharing my programs and circuit diagramsfor others to reference.https://karta146831.pixnet.net/blogI specialize in using the Arduino IDE compiler to develop various functions on MCU, such as AVR,STM,and ESP32, and have experience in all of them. In order to improve the IoT framework, I recentlyfinish to combine Raspberry Pi and ESP32 and develop a data collection and integration systemmyself

  1.Develop fixtures according to project requirements2.Perform maintenance and troubleshooting on faulty equipment3.Improve existing hardware equipmentHardware:1.Through circuit analysis, understand its working wave form and frequency period through the oscilloscope.2.After understanding its principle, connect the test point through the MCU's I/O pin.Calculate and store the burning time of the waveform through the MCU.3.Add the RFID module to read the written ID. At the same time, the ID and related data such as burning time will be sent tothe SERVER when the burning is completed.Software:Develop the MCU program through the ArduinoIDE. Because the chip is dual-core and has independent timers, two independent timers are used to calculate the burning time on both sides simultaneously.The main core is used to process RFID and burning calculations. The secondary core is used to handle the operation of the socket protocol. The reason for choosing this protocol is twofold:1.Due to this protocol belongs to a long connection, there is no cumbersome handshake process of HTTP. After disconnection, the connection speed is very fast, which is very suitable for multiple devices to connect to the server at the same time. 2.This protocol is part of the TCP protocol itself. Although there are other ways to achieve this requirement, choosing this method can communicate directly with the network and reduce the time and cost of maintenance and modification.As for the server part, it is handled by my colleague, and I am responsible for the hardware to the connection part.Project goal:Achieve scheduling planning and time control and record the time and related information and store it in the server. At the same time, it can also know whether the equipment is faulty in real time and can repair it more efficiently
