At best, they have a small display and perhaps a couple of buttons for taking commands; however, they are still fully functioning computers. The programs that run on them can be quite powerful and sophisticated. Since the microcontrol

Our First Assembly Language Program, was originally developed by a group in Great Britain, who wanted to build a successor to the BBC Microcomputer used for educational purposes. The BBC Microcomputer used the 6502 processor, which was a simple processor with a simple instruction set. The problem was there was no successor to the 6502

Before getting into the ., ., and . instructions, we will discuss the representation of negative numbers and the concepts of shifting and rotating bits.

Interacting with C and the SDK, VisiCalc. Many video games were written in Assembly Language to squeeze every bit of performance they could out of the hardware. Modern compilers, like the GNU C compiler, generate adequate code, and microcontrollers, like the RP2040, are much faster. As a result, most applications are written in a

The RP2040 contains eight programmable I/O (PIO) processors that are programmed as state machines with their own Assembly Language instructions. There is a tool in the SDK, pioasm, which assembles these in a similar manner to the GNU Assembler we have u
