About NetSimple

The purpose of the app is to control remote hardware like Arduino, Netduino, Raspberry Pi ... The protocol is TCP / IP (Client). UP: 0, power, 0 DOWN: 0, -power, 0 LEFT: -power, power, 0 RIGHT: power, power, 0 MIDDL

The purpose of the app is to control remote hardware like Arduino, Netduino, Raspberry Pi ...
The protocol is TCP / IP (Client).

UP: 0, power, 0
DOWN: 0, -power, 0
LEFT: -power, power, 0
RIGHT: power, power, 0
MIDDLE: 0, 0, 0 or 0, 0, power (Zero active)

Byte Mode: 3 positions are transfered as 3 bytes (default)
ASCII mode: 3 positions are transfered as text seperated by comma (ended by n)
Session inactive: Each transmission in a Serated connection
Session active: Connection never closed, but if Necessary automatic reconnect (default)
Zero inactive: No return to zero values ​​after release
Zero active: Auto return to zero values ​​after release

Sample code for a server on Raspberry Pi:

#include "stdio.h"
#include "stdlib.h"
#include "string.h"
#include "unistd.h"
#include "sys / types.h"
#include "sys / socket.h"
#include "netinet / in.h"

void error (const char * msg)
{
    perror (msg);
    exit (1);
}

int main (int argc, char * argv [])
{
    int sockfd, newsockfd, portno, n;
    socklen_t clilen;
    char buffer [256];
    struct sockaddr_in serv_addr, cli_addr;
    
    sockfd = socket (AF_INET, SOCK_STREAM, 0);
    if (sockfd          error ( "ERROR opening socket");
