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
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 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

great work your videos are helping us :)

Thanks, it's been great. I would appreciate if you could do this for the st7735 lcd screen as well.
Does it actually generate electric waveform and display it or it just simulate the wave and show it
What do I need to change if want a diferent duty cycle?
How to interface nextion display with esp32 ?
Hi. Don't you need to use the add function in Nextion?
Kindly increase Fontt size of IDE (program Window) it will be clear
Yeah I forgot to do that

Include math.h
@@ControllersTech thanks for reply

"NEXTION_WAVES\NEXTION_WAVES.axf" - 3 Error(s), 0 Warning(s).
../Core/Src/main.c(201): error: #20: identifier "M_PI" is undefined
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,
I also want to join your channel
