The Willar programmer software (often referred to as WLPRO) is a tool used to burn .hex files onto 8051 family microcontrollers (like Atmel 89 series) and serial EEPROMs. While originally designed for older Windows versions, it can run on Windows 10 by following specific driver and port configuration steps. 1. Pre-Installation: Driver Setup Most Willar/WLPRO hardware uses a Silicon Labs CP2102 Go to product viewer dialog for this item. or Go to product viewer dialog for this item. USB-to-UART converter.
Download Drivers: You must install the Silicon Labs VCP Drivers or relevant CH340 drivers before plugging in the hardware.
Windows 10 Tip: If the software fails to recognize the device, ensure the drivers are correctly identified in Device Manager under "Ports (COM & LPT)". 2. Mandatory COM Port Configuration
The WLPRO software often fails to connect if the assigned COM port is too high. It typically requires a single-digit port (COM1–COM9).
Step 1: Open Device Manager and find your programmer under "Ports (COM & LPT)."
Step 2: Right-click the device → Properties → Port Settings → Advanced.
Step 3: Change the "COM Port Number" to a free slot between 1 and 9.
Step 4: Restart the Willar software. It should now show an "ONLINE" green icon at the bottom. 3. How to Program a Chip
Insert the Chip: Place your target IC into the ZIF socket. Ensure Pin 1 is near the socket handle.
Select Device: Click the "Device" button in the software. Select your manufacturer (e.g., Atmel) and the specific chip model (e.g., AT89S52).
Note: For some 8051 chips, you must select the "@ISP" version in the list to avoid "Device ID Errors".
Load the File: Go to File → Load File and select your .hex or .bin file (typically generated in an IDE like Keil).
Execute: Press F5 or click "Auto" to automatically erase, program, and verify the chip. 4. Troubleshooting Common Errors
"Demo Mode": This occurs if the hardware isn't detected. Double-check your COM port (must be 1–9) and use the Hardware → Reconnect option. willar programmer software for windows 10
"Device ID Error": Ensure the chip is oriented correctly and that you have selected the correct chip variant in the software.
"Failed to open device library": This usually means the cfg folder in your software directory is missing or corrupted. Re-download or reinstall the application. 8051 & EEPROM Programmer Guide | PDF | Usb - Scribd
The Willar Programmer (typically software version 1.0 or 1.01) is a specialized utility used to flash firmware and manage device programming, primarily for 8051 series microcontrollers and various EEPROM ICs. It is compatible with Windows 10. Initial Setup & Drivers
Before launching the software, you must ensure the hardware is recognized by Windows 10.
Driver Installation: Install the USB-to-UART bridge drivers (often Silicon Labs CP2102
COM Port Configuration: For the software to communicate with the hardware, the assigned COM port must often be a single digit (e.g., COM2). Open Device Manager > Ports (COM & LPT).
Right-click the programmer entry > Properties > Port Settings > Advanced. Change the COM port number to a single digit.
Establish Connection: Open the Willar software. The bottom-right corner should display ONLINE mode. If it shows "DEMO" mode, the hardware is not connected or the COM port setting is incorrect. Programming Guide The main executable file is typically named WLPRO.exe.
Select Device: Go to Device > Select Device and choose your target chip (e.g., Atmel > AT89S52).
Load Firmware: Click Load or go to File > Load File. Select your .HEX file (usually generated in Keil) and ensure the file type is set to Intel HEX.
Hardware Placement: Place the target IC into the ZIF socket. Ensure Pin 1 of the IC is closest to the ZIF socket handle. Execute Programming: Click Program to fuse the file to the chip.
Alternatively, use AUTO mode to perform Erase, Blank Check, Program, and Verify in a single sequence. The keyboard shortcut F5 can also trigger auto-programming. Supported Devices
The software supports a range of microcontrollers and memory chips, including: Atmel 89 Series: , and 20-pin variants like Serial EEPROMs: 24C series ( through 24C164) and 93C series (93C46/56). The Willar programmer software (often referred to as
Other Brands: Certain Winbond (W78E51) and SST (SST89C54/58) chips. Willar Programmer Download
In the fast-paced world of software development, having a reliable, feature-rich Integrated Development Environment (IDE) or programming utility is non-negotiable. For developers working on legacy systems, embedded devices, or specific microcontroller architectures, finding the right tool that balances power with user-friendliness can be a challenge. Enter Willar Programmer Software for Windows 10—a specialized yet versatile solution that has been gaining traction among professional engineers and hobbyists alike.
But what exactly is Willar Programmer Software? Why is it particularly well-suited for Windows 10? And how can it streamline your programming workflow? In this comprehensive guide, we will explore every facet of this tool, from installation and core features to troubleshooting and advanced tips.
If you are a professional embedded engineer, a maker, or a student who frequently programs diverse microcontrollers on a Windows 10 machine, Willar Programmer Software offers a compelling blend of usability, power, and reliability. Its graphical interface removes the intimidation of command-line tools, while its advanced features (hex editing, batch mode, multi-protocol support) ensure you won’t outgrow it quickly.
The software is available in a free “Lite” version (limited to 64KB firmware size and two chip families) and a “Pro” version (unlimited, $49.99 one-time license with lifetime updates). Given the productivity gains, the Pro version pays for itself after just a few projects.

Note: "Willar Programmer" is not a mainstream IDE (like Visual Studio or Eclipse). It generally refers to niche or legacy programming tools, often associated with microcontroller programming, old BASIC dialects, or specific educational platforms. If you have a specific Willar product in mind (e.g., Willar PIC programmer, Willar 8051 suite), this review covers the general class.
Note: Always ensure that the software executable is obtained from a reputable source to avoid security risks associated with unsigned software.
