In this video, I will show how to use the HAL UART functions.
Before you watch this, please see the video on how to use the STM32CubeMX if you dont already know.

One of the powerful features of the STM32F 3/4/7 MCUs, is the Serial Wire Viewer (SWV) debug. It is a minimally intrusive debugging through the Serial Wire Output pin (SWO). You may send a printf() style strings through ST-Link or other external debuggers and view the strings using ST-LINK utility (free PC software from ST), even after the debug session is ended. SWV is built into the ARM Coresight debug module which is part of every ARM Cortex M3, M4, and M7 cores. Thanks.

Thanks for sharing this info with everyone. I will try to make a video also on this one day.

Thanks again man... When I was trying to learn about STM ARM microcontroller (I was coming from PIC/AVR) your videos were really helpful, specifically these: #1 STM32CubeMX Tutorial #2 How the cube generates the code #3 STM32CubeExamples #4 Free Keil License (This one was amazing hehe) ST Link Update STMStudio Tutorial Only with these tutorials you pretty much gave me the ability to do anything =D Thanks!

very informative video and such good explanation but just clear one thing from where data is being transmitted?

@Weblearning1 4 жыл бұрын

Sorry, I didn't understand your question. From the hardware or software?

@@Weblearning1 I mean which command is used to transmit data?

how to transmit and receive structure containing char int float members through uart ?

@fuzzs8970 2 жыл бұрын

Hi Very nice video simple explanation. How do you send data to an MCU using UART and the nucleo board? Would you mind if ever you have an example and some free time to share your work. Thank you

@Weblearning1 2 жыл бұрын

This video shows on how to send it to the PC on the Nucleo board.

Hi. Thanks for sharing this with us for free. I have a question though is there a HAL function which echos back what we type on the keyboard to indicate that the transmission of each letter was successful? Also do you have a similar tutorial but with interrupts? Thanks

@Weblearning1 3 жыл бұрын

Yes, there is a video with UART and interrupt on my channel. It will be great also if you subscribe to my channel.

@kiptonm 3 жыл бұрын

I missed a step. at 5:02 You said "Put a breakpoint here everytime you see data." How do you do that? If I put a breakpoint there it stops on the HAL_UART_Receive(&huart2, data, 10, 1000); , and it does not appear to get the data sent.

@Weblearning1 3 жыл бұрын

Put a breakpoint at line 106 so it will stop every time you get the data. It will be great also if you subscribe to my channel.

HELPPPPPPPPP TTL to USB converter is must for UART communication in STM32F407vg discovery board ??

@Weblearning1 4 жыл бұрын

This is one of the older boards before DT came out with the nucleo. I think that you can upgrade it to have TTL to USB using the st-link update that's in the cube programmer, but I never tried it and don't know what pins it's using in that board after the update.

@akshaysalunkhe1043 4 жыл бұрын

It says undefined symbol HAL_UART_receive. I have followed all the steps 4 times. What can be the reason? And in my keil v5, the code completion doesn't work. So to write with correct code is a bit difficult. Do you know how to enable it?

@Weblearning1 4 жыл бұрын

What STM32 are you using? Are you using latest CubeMX? What error code are you getting on the Keil? Can you load the IOC and main file and share them?

@kiptonm 3 жыл бұрын

HAL_UART_Receive not HAL_UART_receive. -- upper lower case matters.

how can i find which device path is my device connected to in linux ? (that would be the equivalent of com , ex: /dev/ttyS0)

@Weblearning1 3 жыл бұрын

try something like: ls /dev/tty* That will should list all the available ports.

@ahmetturker2840 4 жыл бұрын

why am I getting different things on com port while transmitting?

@Weblearning1 4 жыл бұрын

Usualy its settings on the speed of the OSC, UART, Terminal etc. Check everything and follow the video again.

speaking of serial console, I was wasted a lot of time on finding a linux alternative for docklight. I am wondering if I can get a hint from you? thank you!

It's hard to find a good alternative to Docklight even in windows ( if you use all the features). The only one that is free and close to Docklight ( on windows ) is Hercules. For Linux, I don't know of such full featured serial interfere.
