How to Generate WAVEFORMS on NEXTION Display || STM32 || Sine Wave || Square Wave

[@ericksonengineering7011]

Thanks for the great tutorial. If the Y axis is Time, like an oscilloscope, the convention is old data on the left, new on the right. So generally data should come in from the right, not the left. Nextion plot defaults the other way. Just change dir to right align. Easy fix.

Can i generate different waveforms from equation? For example i have this equation x(t)=-0.5t+u(t+2)+0.5r(t+2)u(t-1)r(t-2)+r(t-3) I need its waveform on display

great work your videos are helping us :)

[@animeawv]

Does it actually generate electric waveform and display it or it just simulate the wave and show it

How to interface nextion display with esp32 ?

[@LambruscoGaming]

What do I need to change if want a diferent duty cycle?

[@DarkOfRevolution]

Hi. Don't you need to use the add function in Nextion?

Thanks, it's been great. I would appreciate if you could do this for the st7735 lcd screen as well.

Kindly increase Fontt size of IDE (program Window) it will be clear

[@ControllersTech]

Yeah I forgot to do that

Hii Controller Tech, Very Nice Video. first I changed toolchain IDE to ARM-MDK in STM32 CUBEMAX , after that but when I compile this code into Keil5, this is giving error msg error: #20: identifier "M_PI" is undefined PLEASE GUIDE ME , WHERE I NEED TO DEFINED THIS ? i used your code as it, just change toolchain IDE only thanks in Advance

[@ControllersTech]

Include math.h

[@kallehallden8692]

@@ControllersTech thanks for reply I include the math.h, but problem is same "NEXTION_WAVES\NEXTION_WAVES.axf" - 3 Error(s), 0 Warning(s). ../Core/Src/main.c(201): error: #20: identifier "M_PI" is undefined

[@ControllersTech]

It's the pi value Define it somewhere #define M_PI 3.1416

@@ControllersTech thanks you, now my code has been complied. tomorrow i will test this with oscilloscope,
