I have a problem with read from internal eprom

[don_mathew]

reading from eprom is working but when i try to read 15address location and save them one by one in array its not working...this example is not working can enybody tell me what is wrong in this code...on PIC simulator IDE v6.34 on
var led[15] led board gives me sign on PORTB $0F instead $FF

define OSC 8

TRISB = $00
PORTB = $00


i var byte

led var byte [15]

led[0] = %00000001
led[1] = %00000010
led[2] = %00000100
led[3] = %00001000
led[4] = %00010000
led[5] = %00100000
led[6] = %01000000
led[7] = %10000000
led[8] = %10000001
led[9] = %10000010
led[10] = %10000100
led[11] = %10001000
led[12] = %10010000
led[13] = %10100000
led[14] = %11000000
led[15] = %11111111






loop:

for i = 0 to 15

PORTB = led[i]

Next i

goto loop

i found the problem...

i'm c++ programmer and when u define array like this
int var[15]

that means var from 0 to 15 and thats 16 memory addresses

and in pic basic

led var byte [15] means from 0 to 14...i hope that this post will help someone...

led var byte [15]

That's your problem, you defined a 15 byte array and are trying to address the 16th element.

led var byte [15] ' defines a 15 byte array addressed 0 to 14

Change the 15 to a 16 and all should work.

[peterdeco1]

If you define a 16 byte variable, is it the same thing as defining a word variable?

NOPE
16 BITS will be a WORD.
