hi,

I use 2051s for the smallest projects, and I find it adequate to have full control of what I have and where in those ridiculous 128 bytes RAM /2kB FLASH. I don't assume, I calculate used stack space, and so on. I often optimize code for speed/size based on absolute position of variables/arrays, relative position of variables to each other, and alignment of tables in code space.
Why said "not in the whole"? If you like it and know how to do and have some time then no problems. Jan Waclawek said:
You may like it or not, I like it, please don't argue, I know all the drawbacks of it. This is the "little boy" approach - to spare money on parts one has to offer some programming comfort.
By the way, could you, share us with some examples where you need to control things yourself and where Keil cannot help you, please? Especially I ask for: I often optimize code for speed/size based on absolute position of variables/arrays, relative position of variables to each other Just by interest. Thanks, Oleg |
