Hello,

Hi

Is that it is possible to know which instruction is used to display a sentence on lcd16x2, and that sentence scrolls right to left, ie I want a sentence mobile print from right to left, how?.

means that :
#define datas RA_0

if by this you believe that this will then control the OUTPUT state
of PIN_A0 - you are in for a surprise and NOT a pleasant one at that.

you might have b ...

"datas" will be an int1

that is determined by the LOW order bit of the array element you are indexing.

this is very very basic C that we are talking about here, and not the least bit ...

this formula and what it gives results ?

datas=Matris2[0][1]&K;

knowing that :

Matris2[0][1]= 0x7F and K= 0X01

You could try something like this...

i=10;
do {
your print statement goes here......;
delay_ms(1000);
i=i-1;
}while(i!=0) ...

I want to understand the meaning of these instructions (I want a simple and clear explanation) :

1 :
Datas = matris &(0x01)
means : matris & 0x01 , this formula gives us any resu ...

PARTIAL CODE FRAGMENT...

i=500;
do {
your print statement goes here......;
delay_ms(10);
i=i-10;
while(i!=0);

For example, if I have a delay_ms(10000), and I want to displa ...

You can't do this. No one can see numbers that exist for only 1 ms.
Also, the typical 16x2 lcd has a very slow optical update rate.
You probably can only update the lcd at maybe 4 times per secon ...

I want the formula that calculates the timer 0 interrupt frequency 4MHZ, and I want eg the timer0 loaded with a value of 217, which we may well explain the formula for timer0.

In my program, I want the LCD displays the value of my delay_ms, as a counter decrement to zero,
example:
time of 500 ms, the display shows me
temp = 500 = 499= 498= 497=496=495=494=.........=0ms ...

I really thank the gentleman on the forum(PCM PROGRAMMER), because it is the only one who gave me the only solution, even I thank all members of CCS forum ,was interested with this problem.

These are big delays, much more than should be needed, but as a test
it's worth doing, to see if it fixes the problem.

FOR SIR PCM PROGRAMMER :

Post a schematic of your connections to the LCD. Here's an example:
