Hi Sim,
I was so happy read your positive reaction. Now lets get down to the basics : I am planning to use assembly language for your information. Going to be really tough. I would sincerely say you postpone this calculator stuff till you are quite comfortable handling assembly - not a simple thing to do floating point in assembly. It simply is not worth the trouble. If I were to use C language, do i need to use a pc to interface with the microcontroller? Sorry I am not sure about the query. Assembly or C, you do NEED a PC. Otherwise where do you assemble or compile your code ? Don't tell me you are trying to do hand assembly on a hex key pad. To tell the truth I have done that ( 20 years back ) and successfully assembled programs for 16 bit Hex-to-BCD and vice versa on 8085 systems - but then we had no ISP, IAP and stuff like that then.. Sorry I am not really good in this. Is the compiler KEIL C51 easy to get? I really need help here as I really do not have any idea on where to start. Some answers are hard to digest. But since you asked I am telling. Keil is one of the best compilers and is not available free ( nor is there is any C-compiler except SDCC ). You do get an evaluation version of Keil but it is code limited to 2K and does NOT support floating point arithmetic. If you want some free compilers, then there is an option : SDCC. But if you really ask me it is just NO option if you are not a computer geek already. Lots of DOS command line options have to be gone through and at the end you wonder what the heck you are upto. ( Please note that all this is my personal, subjective opinion. Your mileage may vary ) Raghu |
