Hi! Im an electrical and electronic masters student studying in UWE. I have the experience of coding in C/C++/Assembly/Arduino/PIC C/MikroC/MATLAB for more than three years. I also have the knowledge and experience of ELECTRICAL AND ELECTRONICS circuit analysis and design. I also have experience in embedded systems using microcontrollers like PIC, ATMEL, ARDUINO and most of the other types. I have made different kinds of devices varying from radios to drones and more. I am very keen to work on implementation projects I also have studied Artificial intelligence. Im very thorough with subjects like Neural networks, Fuzzy systems, Genetic algorithms and Expert Systems. I have done BCS (British computer society) diploma level.

Hello, I have experience with communication protocols (Modbus, MBus, EnOcean, Lonworks), embedded systems (RPi, ESP8266), SCADA systems, binary and hex data processing. I'm also an experienced Linux user and network administrator. Regarding coding I'm mostly doing Python but I have experience with C as well. I had an ESP8266 a while ago and I used MicroPython on it so we could use it for yours as well. While there are MBus libraries for Python I don't think we could use them on the ESP8266 as they depend on the libmbus library. However if we manage to get some MBus data on the ESP8266 we can see how to decode it afterwards. Best wishes, iticus
