Program memory is read-only, though some variants of the 8051 use on-chip flash memory and provide a method of re-programming the memory in-system or in-application. In addition to code, it is possible to store read-only data such as lookup tables in program memory, retrieved by the MOVC A , @ A + DPTR or MOVC A , @ A + PC instructions.
CircuitPython [5] is an open-source derivative of the MicroPython programming language targeted toward students and beginners. Development of CircuitPython is supported by Adafruit Industries. It is a software implementation of the Python 3 programming language, written in C. [3] It has been ported to run on several modern microcontrollers.
MicroPython is a software implementation of a programming language largely compatible with Python 3, written in C, that is optimized to run on a microcontroller. [2] [3] MicroPython consists of a Python compiler to bytecode and a runtime interpreter of that bytecode. The user is presented with an interactive prompt (the REPL) to execute ...
Turbo51 is a compiler for the programming language Pascal, for the Intel MCS-51 (8051) family of microcontrollers. It features Borland Turbo Pascal 7 syntax, support for inline assembly code, source-level debugging, and optimizations, among others. The compiler is written in Object Pascal and produced with Delphi.
MPLAB X is the first version of the IDE to include cross-platform support for macOS and Linux operating systems, in addition to Microsoft Windows. It supports editing, very buggy debugging and programming of Microchip 8-bit, 16-bit and 32-bit PIC microcontrollers .
A soft microprocessor (also called softcore microprocessor or a soft processor) is a microprocessor core that can be wholly implemented using logic synthesis.It can be implemented via different semiconductor devices containing programmable logic (e.g., FPGA, CPLD), including both high-end and commodity variations.
Instead, some special registers in some microcontroller architectures require special instructions to modify them. For example, the program counter is not directly writeable in many microcontroller architectures. Instead, the programmer uses instructions such as return from subroutine, jump, or branch to modify the program counter.
An AT89c2051 microcontroller in circuit. The Atmel AT89 series is an Intel 8051-compatible family of 8 bit microcontrollers (μCs) manufactured by the Atmel Corporation.. Based on the Intel 8051 core, the AT89 series remains very popular as general purpose microcontrollers, due to their industry standard instruction set, their low unit cost, and the availability of these chips in DIL (DIP ...
