Variable in array

[Gusse]

Hi Al,

Your code worked a bit better but no as Code #2.

Even code below won't run as Code #2. I wounder why? Only difference is that there is a variable in array. And why i = 0-7 is OK, but next are not??

    i=7 : Lcd_SDA = FC.0(i) : Lcd_CLK = 1 : Lcd_CLK = 0
    i=6 : Lcd_SDA = FC.0(i) : Lcd_CLK = 1 : Lcd_CLK = 0
    i=5 : Lcd_SDA = FC.0(i) : Lcd_CLK = 1 : Lcd_CLK = 0
    i=4 : Lcd_SDA = FC.0(i) : Lcd_CLK = 1 : Lcd_CLK = 0
    i=3 : Lcd_SDA = FC.0(i) : Lcd_CLK = 1 : Lcd_CLK = 0
    i=2 : Lcd_SDA = FC.0(i) : Lcd_CLK = 1 : Lcd_CLK = 0
    i=1 : Lcd_SDA = FC.0(i) : Lcd_CLK = 1 : Lcd_CLK = 0
    i=0 : Lcd_SDA = FC.0(i) : Lcd_CLK = 1 : Lcd_CLK = 0 
    
    i=15 : Lcd_SDA = FC.0(i) : Lcd_CLK = 1 : Lcd_CLK = 0 '<- Stop working
    ...
    ...
    i=40 : Lcd_SDA = FC.0(i) : Lcd_CLK = 1 : Lcd_CLK = 0

It seems that 1st character (1st 8 bits) are OK, but next charaxters 1-5 are not working (shows only blanck screen at those places).

you have an extra operation to do in this code (i=7:..), while in code 2 you don't do.

To my understanding these two codes should be as equal as possible. One is using a constant, the other variable (i).

    Lcd_SDA = FC.0(7) : Lcd_CLK = 1 : Lcd_CLK = 0

    i=7 : Lcd_SDA = FC.0(i) : Lcd_CLK = 1 : Lcd_CLK = 0

This extra operation i=7 shouldn't be a problem if arrays support variable(s).

Now when I re-opened this problematic project, it was very clear to me what was wrong. It was too obvious and I can only say "Me Stupid!".
If I have defined a new variable for loop, something else than i, j or k (which were used in other part of the code) then I would never faced the problem.

All codes posted under this topic are working well.

Thanks Al for your help, I appreciate it a lot!
