Dose anybody know the purpose of doing this
void Send_CmdNo(unsigned char command){ CSX=0; RDX=1; D_CX=0; DBUS=command; WRX=0; WRX=0; WRX=0; WRX=1; CSX=1; }
why use WRX=0 3 times b4 WRX=1? wouldn't that just give you WRX=1?
by the way WRX is just
sbit WRX = P7^2;
does it mean on the I/O pin the output will send out 0 three times and 1 one time? It performs that fast?
"you have your opinion, I have mine..."
There's more to it than just opinions - though they definitely play a (significant) part.
The real thing is: you have your particular set of requirements, and I have mine - so what may be "optimum" by your particular set of requirements may well not be optimum by mine
