I have tried
const unsigned char mask[] = {1, 2, 4, 8, 16, 32, 64, 128};
but compiler places it in RAM istead of ROM.
---------------------------------------
Have you read the avr-libc manual & the FAQ therein?
Please read up the useful macros provided for program memory store & access!
If you would have, you would have done this:
const unsigned char mask[] PROGMEM = {1, 2, 4, 8, 16, 32, 64, 128};
And how will you access this array? Read the AVR Libc manual & the FAQ for the
answer!
