Your tutorials are great. I am learning much. I have added buttons as in 1st part and work great. I added the interrupt code, cut and pasted, but that does not work. What troubleshooting can I do to spot where it is not working?
@@stevescott55 hi same mistakes. how did you solve it? i've been writing the code over and over again but cannot recieve anything from HAL_UART_Receive_IT
excuse me ,I did it same ,the button project is working ,but sending string to lcd ,is not working, have you have idea what is the problems tested in Arduino ,it work perfectly, but I want to do it with stm32 ,by the way your UA-cam channel is amazing ,I learned a lot from thanks .
Great video any ... any chance to run this nextion with same stm32 the stepper motor controlls on the touch screen buttons also heating with control the relay ?? i would like to assembly small desktop injection molding machine... any quick question any type of nextion works with this stm32 or need special one any link where i can get this nextion touch screen display?? there are many in china aliexpress with different features they have some ttl usb ,and special usb required i confused to select right one.
Nextion is the company name. Buy it from the official seller. Any display will work as long as it's from nextion. The one i am using in the video is one of the cheapest one (basic model)
@@ControllersTech Great, thanks for your quick respond as i mentioned in above corrosponds about stepper motors, heaters to control them through nextion display any chance to make video :-)?? will be greatfull help for me and for sure 4 others too..
I am not going to make video, but it's pretty easy for you to do it. Just make a UI and use the buttons to send some particular data to the controller.
Hello Controller tech, what I have to do if I want to do it visa versa means if the led gets ON , the button of nextion display should get automatically start
Hello I try your example but without success. I can successfully send data to nextion, but couldn't receive. My nextion is connected to UART3 and I enable global interrupt in NVIC settings of Uart3. I don't know why don't work.
Hi, your comment is two years ago but I want to ask, did you solve? My purpose is when I want to press button on nextion screen, on the stm32 value (for instance i) should be 1, I tried to run the code but I couldn't reach any result in any attempt, any idea?
Using USART LL Drivers and using an interrupt when a button is pressed, but my code is stuck in the ISR. I've noticed it is caused by the ORE flag - any suggestion on how to solve this issue?
ORE is caused when the data is received but the previous data hasn't been read yet. Basically after the data is received in the DR, you need to read the DR. If you failed to do so and another byte gets received, the ORE flag will set
Use prints instead of printh That will print string Also in prints there is a comma.. i have mentioned that in the video also.. Don't confuse it with the dot

Hello, this message comes from Taiwan. Thank you very very much~~I love all of your tutorial videos: )
All your tutorials videos are great , thanks
Great video and explanation as always. Thank you very much.
Спасибо большое вам ,вы делаете большое дело и помогаете студентам
Have to ask, where did you get the cool background on your PC?, it is a very cool "space" image. Thanks in advance

Nevermind - found my mistake. Still would be good to know how to troubleshoot interrupts via breakpoints?

Suas aulas estão top, muito obrigado

Wow, lot of stuff for a button? Thanks.

@@ControllersTech thanks for your reply i will try
did u do injection machine
nice guides, good job
Hello, how to send string not hexadecimal value in part please?
You can send using print command .eg: print "string".
Check 3:55
Can you please make a video,, how to interface Bluetooth module with STM,, forming mesh network..
I already have a video on bluetooth. I don't know what mesh are u talking about..
Hello Controller tech,
what I have to do if I want to do it visa versa means if the led gets ON , the button of nextion display should get automatically start
You just need to send the commands to the display. Check out the rest of the playlist and you will understand this
@@ControllersTech How can I do that?? I watched all the nextion video & tried to implement but still the button is not getting ON automatically.

@@ControllersTech I think the issue is with Mac OS and USB-C. Took the project and same board to Windows and it runs flawlessly.
it can not accept print fonction why it can be
Error:Invalid Variables:print( Double click to jump to code)
l wrote all same
U must be doing some Syntex error. Download the code, open the hmi file and then compare with your syntex.
Sir I will try also I changed printh it's worked how can change hex to decimal at mcu is sprintf working?
Use prints instead of printh
That will print string
Also in prints there is a comma.. i have mentioned that in the video also.. Don't confuse it with the dot
Ho i can't join telegram . Can u refresh links
Link is alright buddy. Some error from ur side i guess
