Thank you for the 5-star rating and kind words~ Since C language is almost essential in embedded firmware, if you want to continue in this field in the future, it would be good to build a solid foundation from the beginning. ㅎㅎ If the foundation is not properly built, you can follow along, but it will be difficult to apply it to other places~ First, I recommend that you watch my lectures and follow along one by one, and then start over from C language after you complete everything. I hope you have a safe and enjoyable development in the remaining contents!
