Raspberry Pi, Blynk and Programming in C Language

Solved

Hi! I have years of experiences with Arduino products. When I switched over from Arduino to the raspberry pi, I was using node js as a quick replacement. I never really used Python so I the simplest solution for my projects was the C programming language. I found some documentation on the internet how to integrate Blynk into node js file and start it from there. But I have no idea how to do that in C language… I already downloaded Blynk and WiringPi library and tested the library with:


sudo ./blynk --token=

It works without any problems. How can I include Blynk in the .c file? Can anyone give me some sample code? I can write further code. My current code in C(i’m still trying how things work in C):

#include <wiringPi.h>
#include <stdio.h>

const int light = 26;
const int doors = 23;
const int dht22 = 4;
const int led = 17;


int main(void)
{
wiringPiSetupGpio(); 
	
pinMode(light, OUTPUT);
pinMode(doors, INPUT);
pinMode(dht22, INPUT);
pinMode(led, OUTPUT);

while(1){		
	printf("Turned on...");
	digitalWrite(led, HIGH);
	delay(2000);
	printf("Turned off...");
	digitalWrite(led, LOW);
	delay(2000);
	}
	
	return 0;
}

Blynk works on the RPi under three currently “acknowledged” languages… finding much support or examples is another thing :stuck_out_tongue: but getting better via the community.

  • WiringPi usies C++ methods, but not all Arduino libraries or Blynk commands are supported. I also find it the more complex to setup.

  • NodeJS (Javascript) while also limited in official example support, seems to be growing… a learning curve for Blynk command integration, but otherwise js is well documented on the web.

  • Python is in Alpha support for Blynk… not much else available yet.

So, what programming language most Blynk users use? NodeJS? What language do you recommend?

Referring to the RPi… who knows :stuck_out_tongue_winking_eye: but I personally prefer NodeJS.

Search this forum for suitable keywords like NodeJS, javascript, RPi, etc.
