How does Keil compare to GCC for ARM7 development? I'm in the process of choosing hw consultants for a medium size project and some use keil and some use gcc. I'd like to know the gotchas involved in going with either option... ...
I am trying to compile a C code using Keil uvision 3. The entire code gets compiled only if I use large memory model by choosing option xdata for target. To use this model I have to use external data RAM which is not possible for me due to some reasons. So I decided to go with pdata option. Can anybody please help me with the exact ste...
Hello, I'm developing a software on 8051 processor. A frequent job is to divide the high and low byte of a 16bit address. I want to see there are how many ways to achieve it. The ways I come up so far are: (say ptr is a 16bit pointer, and int is 16bit int) [note the rn and arn is registers] bitwise operation ADDH = (unsigned int) ptr ...

I'm trying to execute a function from RAM on a Cortex-M3 processor (STM32). The function erases the and rewrites the internal flash, so i definitely needs to be in RAM but how do I do that? What I have tried is this: Copy the function to a byte array in RAM using memcpy (checking that it gets aligned correctly), setting a function poin...

I don't include any of the normal generated C/C++ initialization code so I ...
