[Sdcc-user] PIC16: Array defined within a function

[Theblond <the...@fr...>]

Dear All,

I define an array inside a function.
Unfortunately, all the elements of the array initialized by 0x30,
instead of the given values.
The array can placed in __code, but has the same behaviour.

SDCC : pic16/pic14 2.8.4 #5250 (Oct 12 2008) (UNIX)

The function:
//----------------------------------------------------
unsigned char conversion_by_table(unsigned char index)
{
  unsigned char conversion_table[4] ={'0x01','0x02','0x03','0x04'};
  return conversion_table[index & 0x03];
}
//----------------------------------------------------

The generated code:
