MC-51 a Pascal IDE for 8051 and 80C31

A Pascal powered Integrated Development Environment for 8051 Microcontrollers. It has a Project manager for Assembler and Pascal projects. MC-51 is an IDE for the 8051/80C31 and others. This is from the Institute of Experimental and Applied Physics – Microcontroller course pages.

Integrated Development Environment for 8051 Microcontrollers

To communicate with a microcontroller experimentation board via the serial interface, MC-51 provides a terminal mode. The required parameters for the connection can be adjusted using the main menu. The microcontroller needs to be programmed with an appropriate monitor program (e.g. PAULMON)..

Integrated Development Environment for 8051

The simulator lets you test small programs without any external hardware. It contains all common debugging features (Run, Stop, Single step, Step over subroutine, Run to selected line). You can execute the program step-by-step or set breakpoints anywhere in the program.

The simulator displays the source code with program labels as well as the compiled hex code and the program addresses. All registers and memory locations can be inspected and changed if desired. Numbers may be displayed as hex, decimal or binary values.

Main Features

MCU 8051 IDE and other Tools

A modern graphical IDE for microcontrollers based on 8051. MCU 8051 IDE is an integrated development enviroment. Supported programming languages are C and assembly. It has its own assembler and support for 2 external assemblers. For C language it uses SDCC compiler.

MCU 8051 IDE

This IDE contains simulator, source code editor, assembler, HW programmer and much other tools. Simulator supports over 79 MCU primarily from Atmel.

SDCC – Small Device C Compiler

SDCC was written by Sandeep Dutta and released under a GPL license.

SDCC – Small Device C Compiler

SDCC is a retargettable, optimizing ANSI – C compiler that targets the Intel 8051, Maxim 80DS390, Zilog Z80 and the Motorola 68HC08 based MCUs. Work is in progress on supporting the Microchip PIC16 and PIC18 series. SDCC is Free Open Source Software, distributed under GNU General Public License (GPL).

  • ASXXXX and ASLINK, a Freeware, retargettable assembler and linker.
  • extensive MCU specific language extensions, allowing effective use of the underlying hardware.
  • a host of standard optimizations such as global sub expression elimination, loop optimizations (loop invariant, strength reduction of induction variables and loop reversing ), constant folding and propagation, copy propagation, dead code elimination and jump tables for ‘switch’ statements.
  • MCU specific optimizations, including a global register allocator.
  • adaptable MCU specific backend that should be well suited for other 8 bit MCUs
  • independent rule based peep hole optimizer.
  • a full range of data types: char (8 bits, 1 byte), short (16 bits, 2 bytes), int (16 bits, 2 bytes), long (32 bit, 4 bytes) and float (4 byte IEEE).
  • the ability to add inline assembler code anywhere in a function.
  • the ability to report on the complexity of a function to help decide what should be re-written in assembler.
  • a good selection of automated regression tests.

Cygnal (Silicon Labs) 8051 Port

The Cygnal port was developed on a C8051F120-TB prototyping board (instructions are provided should you wish to use an alternative development board) fitted with a 8051F120 microcontroller. The freeware SDCC compiler was used along with the Cygnal IDE.

8051 Macro Assembler ASEM-51

In 1979 Intel has introduced the 8051 as the first member of the MCS-51 family of microcontrollers. Today hundreds of cheap 8051 derivatives are available from dozens of manufacturers. This makes the MCS-51 architecture so interesting for professionals and hobbyists.

8051 Macro Assembler ASEM-51

Intel had also defined an 8051 assembly language with bells and whistles for all the subtle peculiarities of the MCS-51 core, and offered a well-designed 8051 assembler, the legendary ASM51. Unfortunately, Intel obsoleted all its MCS-51 development tools in December 1993. The original (and IMHO best) 8051 assembler was gone and no longer available! ……. – W.W. Heinz,

ASEM-51 is a two-pass macro assembler for the Intel MCS-51 family of microcontrollers. It is running on the PC under MS-DOS, Windows and Linux. The ASEM-51 assembly language is a rich subset of the Intel standard that guarantees maximum compatibility with existing 8051 assembler sources.

“In the letter, they told me that they had used my ASEM-51 V1.2 to develop the motor-control software for a little Mars car prototype…”

They had validated several 8051 assemblers, and found ASEM-51 to be the most reliable and best documented one.
