Hi,

You need a bootstrap code to initialize things and pass the CPU to OS kernel code which will most likely be written in ASM and you can code the rest of the Kernel including HAL and...

Hi,

I suggest you to download the main PIC 16F84A manual. (or the one related to your PIC) There you will see a list of registers and opcodes. Actually for PIC registers is like memory (there...

Hi,

There are some 3rd party drivers that let you access IO ports through them, but you call a function on their DLL not the OUT opcode.

Hi,

If your target CPU is using Intel SpeedStep technology or some kind of PST, ODCM technology then the speed will be varying over time and although you can access the adjusted speed too, the...

Hi,

OOPic has a compiler of its own and compiles Java, Basic and C like constructs to its own ASM code. If you didn't have bought an OOPic board and I would suggest PIC microcontroller (...

Hi,

There is a loop which turns 3 times so 4 of the instructions are called 3 times so you want a 17 by 2 table or the end result ? The last two puts will give 3 and -11 respectively.

Hi,

Since the 80386 all x86 processors (except AMD's new x86-64) are 32 bit and support 4 operating modes : 8086 VM, 16 bit real mode, 16bit protected mode, 32bit protected mode. You can use...

Hi,

Of course you can do that unless you use your app under a NT based (W2K, XP, Vista) OS. Even on those OSes where there îsn't a real DOS but an emulation layer, the mulation layer works to...

Hi,

There are a lot of free compilers for the PIC Family of microcontrollers for C, Pascal, Basic languages. But if you need to code in PICs ASM then the best resource is the 16f84a's manual...

Hi,

"The Art of Assembly" is the legendary resource on this, and its free although it is copyrighted material. Check the links below for a HTML and PDF versions or just Google it.
