i'm working for a project "touch screen controlled robot" in which the direction in which the robot has to move is given by user through touch pad and its a working ....but wired i.e transmitter and receiver part are connected by wire
i would like to make it wireless.... someone suggested me that using rf tx&rx is one way to do it.... but the problem which i faced using rf (433MHz) is that
1. it was working properly only when data alone is transmitted(i.e no calculation involved)
2. but in the program what i wrote requires around 200 ms to generate a state(i.e stop,forward,backward,left & right....... i represented in program by S,F,B,L & R at baud rate of 1200---no problem with baud rate ).... it is generated based on the movement of finger not by arrow mark like keyboard
3. because of this delay the noise is very high during this interval of 200 ms hence data received will not be correct
4 since it involves adc conversion and other comparisons i need something which can make it wireless
i wanted to know can zig bee solve this problem please share your experience of working with zig bee....and how to use it
if it cannot solve my problem suggest me any other way to do this
