Reads51 is Rigel's Integrated Embedded Applications Development System, an IDE (Integrated Development Environment) that supports the Rigel 8051 embedded controller board family. The IDE supports several toolchains, most notably the previous READS v3.x assembler and the RChipSim v3.x simulator. This makes Reads51 an upgrade to previous software tools. In addition, Reads51 contains a SmallC-compatible C compiler for the 8051 microcontroller family.
Reads51 IDE Rigel 8051
Reads51 runs on an IBM PC or compatible host. Reads51 allows users to write, compile, design, debug, download, and run application software in the MCS-51 language. Reads51 contains a C compiler, relative assembler, linker/locator, editor, chip simulator, assembly language debugger, and user-friendly host-to-board communication.
Debugging functions include breakpoints, single-stepping, source-level debugging, inspecting & modifying memory, internal registers, and special function registers. The MCS-51 instructions include a comprehensive on-line help system.
All Reads51 functions can be activated from the menu, toolbar, or with a hot-key combination.
Software Examples
Source code is also provided for experimenting with the capabilities of Rigel's boards and Reads51. Several examples are designed to provide an overview of the features of the 8051 microcontroller family, especially digital and serial I/O, timers, counters and interrupt logic. In addition there is software such as; routines for keypads, LCDs, stepper motors, and DC motors.
Users are encouraged to modify the provided software samples, this is intended to develop more specific versions of their applications. User source code can be accessed through system calls.
Download
You can download the application on the Rigel Official Web Page.

Contoh Program Assembly Testing Port
In the world of electronics, one thing that should not be ignored or forgotten is checking the supporting equipment, to ensure that the tools we use can work properly according to their function, this service package is often known as calibration.
No exception when we are designing a system to be implanted/embedded into an IC (Microcontroller or Microprocessor), we usually use a port indicator as a tester, to ensure whether our program is running as it should.
This is the reason why this program was created, so that we can ensure that the indicator port we are using is working properly, and if there is damage, then we can do further troubleshooting such as; replacing the indicator light or checking the connector, etc.

Hi Mierza, If there is, please use it. If not, maybe I will add it another time.. thank you
Yes, please.
Example of 7 Segment Initialization Assembly Program
Initialization is the process of finding and using the values assigned to the variable data used by the system. A system is installed with standard or user-defined values by considering certain aspects so that the unit has a specific function.
A system initialization parameter can be set by default or dynamically from the console, this is usually done during the startup process.
Initialization aims to determine the initial base solution, the optimization test stage aims to check whether each transmission and component has been installed correctly (pass).
Performance at the initialization stage is determined by the complexity of the method algorithm, changing the centralized system to a distributed system.

Example of Sliding LED Assembly Program (Ring Counter)
Ring counter or familiarly called Walking Led, is a logic circuit consisting of a row of shift registers. The output of the shift register is then fed to the input of the first register, and so on.
The most popular ring counter is the Johnson counter model, because it is capable of independently initializing all registers to zero, without requiring an external injection of the first bit count at start-up.

ANDRI MARSEL Apr 30, 2017, 09:29:00 bro, why is my LED running so fast? even though I've copied the program bro.??

Many, if the above I use the program 51 RIGEL CORP
Maybe it's because the architecture is different, bro. Just try modifying the delay part, bro, try increasing it.
