Development Tools

This chapter describes the installation and usage of Keil and FLIP. These tools are required to write, debug, and execute programs for the Pt-51 Board.

Keil µVision IDE

Keil µVision is an integrated development environment (IDE) for editing, compiling, running, and debugging programs for the 8051 microcontroller. It is integrated in the sense that the same environment is used to perform all these tasks. For loading programs into the 8051 microcontroller, we will need the FLIP tool.

An non-integrated workflow would be where different tools are used for different tasks. For example, Visual Studio Code could be used for editing the program and a command line compiler could be used to compile the program.

At a high-level description, the Keil IDE workflow is as follows:

Create a new project.
Specify the target device while creating the project.
Create a new source file in the project.
Build the project.
Fix any compilation errors and rebuild.
Once program compiles without errors, use the debugger to check correctness of execution.

See the slide deck and video in the following section for more detailed instructions.

Download and Installation

To download the Keil IDE, you will need to register at https://www.keil.com/demo/eval/c51.htm

Windows users can install Keil by simply double-clicking the downloaded file.

Linux users will need to install Keil using Wine.

On Ubuntu, install Wine by running the following command. Use the relevant package manager for other Linux distributions.
```
sudo apt install wine-stable
```
Run the following command in the folder where c51v960a.exe was downloaded.
```
wine c51v960a.exe
```

Getting Started with Keil µVision IDE

The following slide deck has an introduction to using the Keil µVision IDE. The pdf can be downloaded by clicking here.

A video walk through of the features of Keil µVision IDE.

Debugging in Keil

The following slide deck has instructions on debugging programs with the Keil µVision IDE. The pdf can be downloaded by clicking here.

Note: If Keil µVision keeps crashing on pressing the Start\stop debug session, then follow these steps.

Right click on the target folder (at the left pane).

Select ``Options for Target ````.

Select the Debug pane.

Change the Parameter field to the right of Dialog DLL with text DP51.DLL to -p51.

Tick the Limit Speed to Real-Time checkbox.

See the below screenshot.

Pt-51 board device driver installation instructions

The pdf of the above slide deck is available here.

DFU Programmer Installation and Use

Installation steps for Linux
- Run sudo apt-get update -y
- Run sudo apt-get install -y dfu-programmer
Installation steps for Mac
- Press Command+Space and type Terminal and press enter/return key.
- Run the following in the Terminal app: ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null
- If the screen prompts you to enter a password, please enter your Mac's user password to continue. When you type the password, it won't be displayed on screen, but the system would accept it. So just type your password and press enter/return key. Then wait for the command to finish.
- Run: brew install dfu-programmer
Use (common for Linux and Mac):
- Run the following command for erasing flash: sudo dfu-programmer at89c5131 erase.
- Run the following command for programming flash: sudo dfu-programmer at89c5131 flash <hex_file.hex>. Make sure you are in the directory where your hexfile is present when you run it.

Pt-51 Board Resources

This chapter has the resources related to the Pt-51 Board and the 8051 micocontroller.

User Manual

Programming and Testing

Running a Hex file on Pt-51

Assuming that you have installed Keil and FLIP tools successfully.

Download the following assembly file and compile it to generate the hex file for a simple LED test. led.asm.
Take a look at the video below for the procedure to dump a hex file that will be executed on the Pt-51 kit.

Completing, the above two steps lets you test the LEDs on Pt-51 kit. This is a quick check of the Pt-51 kit and installed tools.

Testing the peripherals of Pt-51

A test file has been developed to test all the peripherals of Pt-51.

Download this test file. pt51_test.hex.
Program the Pt-51 using the downloaded pt51_test.hex file.
Details of the peripherals being tested and their success/failure can be understood from this set of slides. Make sure all the tests run successfully.

The pdf of these slides is available here.

FAQ

How to resolve "µVISION DEBUGGER: ERROR 65 (ACCESS VIOLATION)" error?

The µVision Debugger generates the following error whenever we try to write to the variable:

Error 65: Access violation at 0x00000004 : No 'write' permission
Cause
- When the µVision Debugger loads an executable program, it creates a memory map using the program and data segments from the program. Code segments are marked as executable while data segments are marked as read/write. All other memory is unmapped and is, therefore, not marked for any type of access.
- The µVision Debugger checks that all memory accesses are made to objects that are defined in your C program. For any access that is outside of a defined C object, the µVision debugger generates an Error 65: access violation message.
- By default, the debugger allows only memory accesses to valid data objects. This is useful for finding uninitialized or incorrectly initialized pointers, for example. Usually, there is a programming error when you try to access unexpected locations.
Resolution
- If the error 65 is for an area that should be accessed, update the memory map the simulator uses. Define all the memory ranges that your program is permitted to access. Ensure that you set the permissions (read, write, execute) for each range to match your actual hardware.
  - Use the Debug - Memory Map dialog. Enter a range in , format, choose the permissions (read, write, execute) and click Map Range
  - Enter the MAP command in the Command window.
```
MAP  C:0xF800, C:0xF8FF  READ WRITE  // allow R/W access to IO space
```
- For the 80x51 targets the address might be prefixed with a memory space specifier as described in the table on this page. For example, C:0xF800 refers to Code address 0xF800.
- Any memory map changes could be lost during the next debug session. Once you find the correct memory put the required MAP commands into a debugger INI file that can be entered under Project -> Options for Target -> Debug and create an initialization file.
