Subject: How to declare an array of constants to be stored in FLASH only
Date: Mon, 03 Oct 2005 21:03:00 -0000	[thread overview]
Message-ID: <E8FF7C7357ECB34F9B7F507B05A2343A3D8173@sv-exch01.rftechnologies.com> (raw)


I am using the GCC compiler for an Atmel ATMEGA128 target.
I would like to declare a large array of constants so that it is accessible from FLASH and does not use RAM.
static const unsigned char Data[] = {0x45, 0x23, .....}
The above seems to copy the constant data into RAM
Is there a way to declare the above array so that it does not create an initialized data in RAM
I was able to do this with a different compiler/linker with the __flash keyword
static const __flash unsigned char Data[] = {0x45, 0x23, .....}
Thanks in advance,
Jeff
