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....

Thank you very much! It's the best video about my problem: how to send data from stm32 to Nextion. You are the best.

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
sir, how to change page by uart from stm to nextion
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
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 ?
Could explain how get numeric value from Nextion ?
If u mean the button thingy, just look in the playlist... There is another video there
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
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..
Great , is it possible to sent moving graphics instead of string texts ?
What kind of graphics ?
Can you explain the wiring thanks
Tx to Rx and Rx to Tx
@@ControllersTech thanks.
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 show get data from screen
Not sent
