3 positions are handled either as text or bytes.
The range of the values x,y (1. control) and z (2. control) are between -100 and 100.
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
The purpose of the app is to control remote hardware like Arduino, Netduino, Raspberry Pi ...
V1.1:
- Changed default mode
- Session to hold connection
V1.2:
- Tablet modifications
V1.3:
- Zero: Auto return to zero values on/off
- Remember last settings
V1.4
- Improved TCP/IP connection
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"
