declaring an array in embedded C - satish - 03:19 21-08-08
hi iam new to this embedded field iam had a problem in declaring an array in embedded C..iam using SDCC compiler for compilation..if u know..please pass that information. thank you

One thing that is a bit different in embedded is that you can (usually) infleunce where your data goes. If it is constant data then placing it in "code" may help (and the 8051 is quite good at indexing small arrays in the code space).
