Ótima aula e exemplo, faz dias que estou tentando usar o display nextion com o stm32, muito obrigado por compartilhar seu conhecimento, seus exemplos ajudam muito no aprendizado.
You know, more than just amazing I could not find another word. I'm trying to combine your tutorial with somthing that comes in my mind. I wonder to build an UI based on your tutorial. Where the screen could contain 7 text fields and on the other hand a feature of scrolling text kinda of passing text from text field to another but I have to keep update the last field since it comes from the stm32 board. Is it possible to get a tutorial on this purpose.!? Cause I'm stacked in the idea....
@@ControllersTech void NEXTION_SendData (uint8_t *data) { char buf3[50]; int len3 = sprintf (buf3, "n0.val=%d",data); HAL_UART_Transmit(&huart1, (uint8_t *)buf3, len3, 1000); HAL_UART_Transmit(&huart1, Cmd_End, 3, 100); }How to make function with second parameter?
Thank you very much! It's the best video about my problem: how to send data from stm32 to Nextion. You are the best.

Thank you so much! It's a very good video, easy to understand. It will help me a lot
Can you do a tutorial on using external buttons to control the display. For example a menu system ( up, down, enter).
Yeah of course.. they will be coming soon

stm 3,3 v, nextion 5 v. is it problem for rx, tx pin
No its not a problem. The tx and rx pins works at 3.3v
sir, how to change page by uart from stm to nextion
Hello,thx for you tutorials. How to send data not string? n0.val=100 for example?
Check other comments in this video. I have answered the same question..
@@ControllersTech void NEXTION_SendData (uint8_t *data)
{
char buf3[50];
int len3 = sprintf (buf3, "n0.val=%d",data);
HAL_UART_Transmit(&huart1, (uint8_t *)buf3, len3, 1000);
HAL_UART_Transmit(&huart1, Cmd_End, 3, 100);
}How to make function with second parameter?
What second parameter ? If u are trying to send another value, then use this function again
@@ControllersTech LIke you first function :void NEXTION_SendString(*char ID,*char string)
Just use the function i have created. If u want to send the value and not the string, modify that function..
how can we show sensor data on display eg temp sensor ,or moter speed on display ? plz help on this
Check the last video in nextion playlist
Great , is it possible to sent moving graphics instead of string texts ?
What kind of graphics ?
Could explain how get numeric value from Nextion ?
If u mean the button thingy, just look in the playlist... There is another video there
Como receber valores de 0 a 5000 no stm32 do display nextion? (How to receive values from 0 to 5000 in the stm32 of the nextion display?)
Number ?
Para enviar valores ao nextion esses comandos estão errados?
uint8_t Cmd_End[3]={0xFF,0xFF,0xFF}; //Finalizador Nextion.
char buf3[50];
int len3 = sprintf (buf3, "n0.val=\"%d\"", 20);
HAL_UART_Transmit(&huart3, (uint8_t *)buf3, len3, 1000);
HAL_UART_Transmit(&huart3, Cmd_End, 3, 100); //Finalizador Nextion.
int len3 = sprintf (buf3, "n0.val=%d", 20);
@@ControllersTech obrigado.
Can you explain the wiring thanks
Tx to Rx and Rx to Tx
@@ControllersTech thanks.
Can you show get data from screen
Not sent
