Hello, this is Je어쟁이.
I’ve just uploaded a new video summarizing the basic principles of UART communication.
Those of you who are already taking the course have probably used UART at least once. In this video, rather than simply following along with the code, we’ll go back and examine the form in which UART actually transmits data.
We explained step by step how TX/RX are connected, why the Start Bit and Stop Bit are needed, how a single character is converted into actual bit data and transmitted, and what the relationship is between the Baud Rate and Bit Time.
Especially at the end, we transmit actual data from an STM32 and directly measure the UART waveform with an oscilloscope to see how the bit structure learned in theory appears in a real signal.
Even for those already taking the course, it may be useful to review the UART section or to gain a clearer understanding of how serial communication works.
Even UART, which you may have used comfortably when writing code in the course, will be much more helpful for debugging later if you understand how the actual signals are generated and received.
The video has been uploaded to the YouTube channel.
Please check it out whenever you have time!
