Hi All,
I am trying to write functions at specific locations. I am using KEIL 4 IDE ... and LPC2478 Though I could find a keyword "FIXED" which says one can write function at specific locations, but don't know how to use it .
This is what I want to achieve ....
for eg :
void main(void){ function_1(); function_2();
}
void function_1(){
void function_2(){
I need "function_1()" to be placed at specific location ...say...address 0x2000.
and
I need "function_2()" to be placed at specific location ...say...address 0x4000.
Can this be achieved ....and if yes How can I do this ?
All suggestions are welcome.... (I could not understand how the keyword "FIXED" works )....
Thanks ... K.Ganesh

Using a jump table:
Microsoft did it back in the 6502 BASIC days to make calls to the MONITOR functions.
The BBC Micro did it to call functions in the OS.
Wheels. They only exist so they can be re-invented.
