Purpose of this channel:- During my Master's I realize the problem of limited resources and tutorials on the internet specifically in the field of Embedded System. I am sure you can also relate to this problem and might have already faced it while looking for some specific topic/tutorial related to Embedded System. This platform is an attempt to identify such untouched topics and concepts which are known to be the fundamentals and building blocks for Embedded System and make them easy to understand with the knowledge and experience which I have gained working with various MNCs. You can check out various playlists already made available on this channel for example Fundamentals of Embedded System, C Programming Language Tutorials, CAN Protocol, and Unified Modeling Language (UML).
I deeply appreciate the support so far you have provided to this channel :) Thank you...
Are most big companies using the SCRUM / Kanban methodology (or framework) to satisfy the AGILE/Waterfall/V-Model philosophy (SDLC) ? I'd like to move away from a rapid-prototype environment to something more formal in order to develop high quality/safe products containing embedded software.. for ANY industry.. Aerospace (like Lockhead's SEAL Level X, Boeing , DDPMAS, DAL A to E etc) , Medical or Nuclear industries.. even Automtovie. I'd love to see a trivial project example that shows all the steps and outputs. For example, assuming I document the process on how the code is generated, what constitutes proof that it's safe? Static Analysis? Code Coverage - Statement (Level C), Decision (Level B), MCDC (Level A)? Who defines the unit tests? I imagine there are differences between the industries.. FAA : DO-178X , DO 331 , ARP4754A , ED-12C FDA : 13485 , ISO14971 , IEC 62304 , SaMD and DOE Nuclear : 414.1x, (Automotive : 26262) but what are the typical tools/software needed, and the typical document/artifacts in the various stages of the software life cycle? I saw a good video by CEMILAC Education Program "Airborne Software Development & Certification Process" and it's a bit overwhelming: Requirement Management - (IBM Ration) DOORS, JAMA, Xebrio, rmtoo florath , doorstop-dev / doorstop , reqview Static Structural Source Code Analysis - Parasoft, PolySpace, CodeSonar, horusec , SonarCloud, veracode PREFast, TBrun, LDRA Dynamic Analysis / Modified Condition/Decision Coverage (MC/DC) - VectorCAST, RapiTest Traceability Tools: Reqtify , Polarion , McCabe Configuration Management / Storage and Version Control System - Git, SourceSafe, Mercurial, MS TFS, ClearCase QA / ALM- Helix ALM for Managing Artifacts, Establishing Traceability, Documenting / Enforcing Processes, etc (I)V&V / Unit Test Automation - VectorCAST, LDRA Testbed , Mathworks Simulink DO Qualification Kit Continuous Integration / CD - Continuous Delivery/Deployment - Jenkins, Bamboo, or GitLab CI/CD And what is the general attitude towards open source software (ex. FreeRTOS) and code-generation tools (ex. ST's Cube MX)? Also, how do CPLD and FPGAs fit in to the embedded software picture.. since not exactly software nor hardware, since they are programmable devices written in an programming language like VHDL , (system) verilog , Amaranth HDL ? How would DO-254 apply to HDLs?
At 1:56 I don't understand how the P-MOS can be activated by the 1. If '1' is logic high (3.3V/Vcc), then the voltage of the gate relative to the source (Vgs) is simply 0, and the P-MOS is not conductive. To activate the P-MOS, Vgs needs to be negative -- that is, the gate voltage would need to be logic low (0V/GND) while the source voltage is 3.3V/Vcc, meaning Vgs = -3.3V. And again, at 2:21 , if there is 0V on the gate of the P-MOS, the P-MOS will activate due to the negative Vgs, which means both mosfets will activate and Vcc and GND will be 'shorted' by the connected drains. What am I missing?
Hi everybody, I have a Honda civic 2010 coupe is false error link when I setup ODB2 scan then I probed CAN-H and CAN-L look ok but L-line is a straight line 9 volt dc, it has no wave form during ignition is on or engine is running. I am not sure what it should look like before I continue to chase it down to find the problem. Anyone has any suggestion please!!! thank you every much. I don't want to bring it to the shop or dealer because the value of my car might be cheaper than the cost to repair.
