Blinky and Running LEDs 🟣 STM32 Programming with STM32F103C8T6 Blue Pill C++ in STM32 Cube IDE 

That's the plan!

The base skillset stays mostly the same. Working with one ARM based MCU opens up many paths. Like with anything. The more you do it the easier it gets. You are likely to work with a eclipse based IDE or vsCode with most MCUs available. Its is only Microchip that feel like they need to be unicorns. PIC is not popular in the industry. The only reason it is still relevant is that universities insist on using them in there courses. I have not met a working engineer that would favor using a PIC. At least this is the consensus in my location.

@@BinderTronics Yes, I think this is the same in my location too.

Don't worry C++ looks foreign every one. Even the guys that claim to be experts.

4:12 contains the declaration for MX_GPIO_Init

Get an original st-link-V3 mini ~$10. I used a Segger J-link EDU, it is no longer manufactured. ST does not like people using closes with their software. If you setup a you own tool set the clones work fine. If you want to use ST tools you are going to have to use a Segger or an ordinal ST-Link. If you got a Nucleo you can hijack the ST-link from it.

GPIOBase constructor is not running, Try running the debugger and step the code. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vlJ_80EbMS8.html around the 8 min mark I use the debugger.

@@BinderTronics Thanks for your reply and time. I will take my time to review it and try to debug it to find out what's happening.

@@BinderTronics hey there! I managed to fix it. I was missing a line GPIObase::init(); in gpio_hal.cpp. I could focus on that file since the init was there so I double checked again. Now my questions are, What was the purpose of doing these files and settings with public and private. its to being able to init the Douts, keep them away from the main file and being able to call them with a short name? I am trying to understand the logic behind. Thanks!

For files. It simply comes down to organizing code and reuse. Imagen having a book without chapters or a index. This is what will happen if you use a single files. Real projects can easily be 10k-3M lines depending on complexity. So we break the project down into files that govern a particular purpose. gpio_hal.h only governs the outputs and inputs. The name used or length has no relevants. Just name it something logical. For class access modifiers: public: anything can access it. private: only that class can access it. protected: only that class and its derived classes can access it. It is object orientated programming (OOP) theory. Covered in most courses for languages that have OOP components.

@@BinderTronics Thanks for the explanation. Pretty much clear to me now.

I would recommend C over C++ as a first language. I did not learn from books. What I recommend in general for whatever language is to lookup a course on RU-vid to get the fundamentals. Once you got fundamentals start your own project to solve a problem you have or something you find interesting. The is the only way you will truly learn is by doing, not by parroting tutorials. freeCodecamp.org has a metric ton of courses. w3schools is good if you want a text base course. The Cherno is pretty good for C++ as a supplement (I like the code review stuff). Fair warning, C++ can become awful real fast. GPT chat is also a fantastic learning tool to figure out how something works. It produces awful code most of the time and can't debug but it is still great if you know nothing about a topic.

@@BinderTronics Oh that's great. Even though I'm no expert in C. I played something with PiC16 using C for embeddeds but I found out that as things get complex is a little hard to deal with, also the capabilities of the pic itself. But thank you for the tips. Even saying that helps by doing it's useful. Today I discovered that one class that I'm taking will focus in C++ for the rest of the semester and I have to code a big project. this will help me with this too . we are using Arduino Uno there. so I will play with both. Thanks mate

Have a look at the ATmega328P series. It is the same chip as the Arduino Uno.

The reference manual covers it. This series is based on the HAL that ST provides thus the registers are handled by the abstraction, no need bust your head on how the IO works. If you want to know how IO works down to the CPU level. I would recommend having a look at the guys that are building their own CPUs. James Sharman has recently added IO to his custom CPU.

Don't know about your location but the stm32 blue and black pill boards are price comparable to a UNO R3. The STM32 boards can also do more.
