How to send String to the Nextion display || STM32F103 || CubeIDE

[@СвятославКороль-ы7э]

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

[@HenriqueOliveira-fp5bg]

Thank you so much! It's a very good video, easy to understand. It will help me a lot

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.

sir, how to change page by uart from stm to nextion

[@vedan7]

Can you do a tutorial on using external buttons to control the display. For example a menu system ( up, down, enter).

[@ControllersTech]

Yeah of course.. they will be coming soon

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....

[@antonioescamez4549]

Could explain how get numeric value from Nextion ?

[@ControllersTech]

If u mean the button thingy, just look in the playlist... There is another video there

Hello,thx for you tutorials. How to send data not string? n0.val=100 for example?

[@ControllersTech]

Check other comments in this video. I have answered the same question..

[@Денис-з5е7ъ]

@@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?

[@ControllersTech]

What second parameter ? If u are trying to send another value, then use this function again

[@Денис-з5е7ъ]

@@ControllersTech LIke you first function :void NEXTION_SendString(*char ID,*char string)

[@ControllersTech]

Just use the function i have created. If u want to send the value and not the string, modify that function..

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?)

[@ControllersTech]

Number ?

[@abiramiselvaraj9285]

it works! thanks

[@Innopeace]

Great video. Thanks,

[@eng.shh80]

Great , is it possible to sent moving graphics instead of string texts ?

[@ControllersTech]

What kind of graphics ?

[@luizazeredo5197]

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.

[@ControllersTech]

int len3 = sprintf (buf3, "n0.val=%d", 20);
