#133877 - resons for extending memory Responding to: ???'s previous message |
hello
i think i havent explained my problem clearly.the program i have in c(keil)is consuming more than 127 bytes and it creates an error message saying that the data segment has overflowed.so the doubt is how can i increase the data segment or optimize the code so that it occupies less ram. thanks erik for pointing out that the higher 128 bytes of RAM can be accessed using indirect addressing only and registers by direct addressing. i have refferd the keil manual also but i am finding it a bit difficult to follow. regards pradheep |
