HI,there
I made a simple code to turn on/off LED
include "NexButton.h"
include "NexText.h"
NexButton b0 = NexButton(0, 1, "b0"); NexButton b1 = NexButton(0, 6, "b1");
char buffer[10] = {0};
NexTouch *nex_Listen_List[] = { &b0, &b1,
NULL };
/** * Button to return the response. * * @param ptr - the parameter was transmitted to pop event function pointer. * */ void aa(void *ptr) { NexButton *btn = (NexButton *)ptr; memset(buffer, 0, sizeof(buffer)); btn->getText(buffer, sizeof(buffer)); if (strcmp(buffer,"ON")) { digitalWrite(13, HIGH); strcpy(buffer, "ON"); }
btn->setText(buffer);
}
/** * Button to return the response. * * @param ptr - the parameter was transmitted to pop event function pointer. * */ void bb(void *ptr) { NexButton *btn = (NexButton *)ptr; memset(buffer, 0, sizeof(buffer)); btn->getText(buffer, sizeof(buffer)); if (strcmp(buffer,"off")) { digitalWrite(13, LOW); strcpy(buffer, "off"); }
btn->setText(buffer);
} void setup(void) { nexInit(); b0.attachPop(aa, &b0); b1.attachPop(bb, &b1);
//setting port OUTPUT pinMode(13, OUTPUT);
//initializing port digitalWrite(13, LOW);
} void loop(void) { nexLoop(nex_Listen_List); }
and I made a hmi file when I press b0 , aa function will turn on LED and start to count down, when I press b1 LED will turn off and count down over.
but I am curious , Could "click" function can instead of touch screen to off the LED because my project can't turn off LED though "click" had "touch" b1 button
I am sorry for my bad English hope you guys know what I said
btw my nextion is 7''
