The Willar Programmer (often associated with the WLPRO software) is a specialized tool used primarily by engineers and hobbyists to "burn" or program hex files into microcontrollers like the 8051 series, AVR, and various EEPROMs. While the software has been around for some time, getting it to run on Windows 10 requires specific configuration to ensure compatibility with modern USB drivers. Key Features of Willar Programmer Software
This software serves as the interface between your computer and hardware like the SP200SE or SP300 programmers. Its primary functions include:
Chip Support: It supports a wide range of ICs, including Atmel 89 series (89C51, 89C52, 89S51, 89S52), SST, Winbond, and MegaAVR/TinyAVR devices.
Buffer Management: You can load .hex files (generated from compilers like Keil) into a buffer, view the data, and then program it to the target chip.
Automated Modes: The "Auto" button allows you to perform Erase, Blank Check, Program, and Verify in a single sequence.
USB Powered: Most modern versions (like those using the CH341 or CP2102 chips) draw power directly from the USB port, eliminating the need for external adapters. How to Install on Windows 10
Windows 10 can sometimes struggle with the older USB-to-Serial drivers used by Willar hardware. Follow these steps for a successful setup:
Install USB Drivers: You typically need either the Silicon Labs CP210x drivers or the CH340/CH341 drivers depending on your specific hardware module. COM Port Configuration:
Open Device Manager and find the device under "Ports (COM & LPT)." Right-click, go to Properties > Port Settings > Advanced.
Change the COM Port number to COM5 or lower. The software often fails to detect hardware if it is assigned a higher port number.
Run as Administrator: Since the software is an executable (.exe) that interacts directly with hardware ports, it is recommended to right-click the program and select Run as Administrator.
Confirm Online Mode: Once opened, check the bottom right corner. It should display "ONLINE" to confirm the hardware is correctly recognized. Common Uses in Embedded Systems willar programmer software for windows 10 new
8051 Development: Burning code for legacy and modern 8051 variants used in educational kits.
EEPROM Programming: Reading and writing data to 24 and 93 series serial memories.
Code Protection: The software includes a "Lock" or "Protect" function to prevent others from copying the code once it is burned onto the chip. SP300 programmer resources page
Willar Programmer is a straightforward utility developed by Willar Electronics for programming 8051-series microcontrollers (like Atmel 89C51/52) and serial EEPROMs. It is known for its fast, USB-based programming and does not require external power.
Guide to Installing and Using Willar Programmer on Windows 10 1. Software Installation
Download: You can find the latest version (e.g., v1.01) on Software Informer or direct repository links from retailers like Hacktronics.
Setup: The software typically comes as a standalone executable named WLPRO.exe. Simply copy the folder to your local hard disk (C: drive or Desktop) rather than running it from a compressed zip. 2. Hardware Setup & Drivers
Driver Installation: Most Willar programmers use the Silicon Labs CP2102 or CH340 USB-to-UART bridge. Download and install these drivers from the manufacturer's site or the provided Silicon Labs Support Page.
Connection: Plug the programmer into a USB 2.0 port. A green LED should blink once, indicating it is powered and ready. COM Port Configuration: Open Device Manager and expand "Ports (COM & LPT)." Find the programmer (e.g., "Silicon Labs CP210x").
Crucial Step: Ensure the COM port number is between COM1 and COM9 (ideally below COM5) for the software to detect it. Change this via Properties > Port Settings > Advanced. 3. Programming Your Chip

The Willar Programmer (often associated with the executable WLPRO.exe) is a utility used for burning hex files onto microcontrollers, primarily the 8051 series like the Atmel 89C51 and 89S52. While the software was originally designed for older Windows versions, it is compatible with Windows 10 if the correct USB-to-UART drivers are installed and specific port settings are applied. Software and Driver Installation
To use the Willar software on a modern Windows 10 system, follow these steps:
Download the Software: The software is often provided as a standalone executable (WLPRO.exe) that does not require a formal installation process; you can simply copy it to your desktop or a dedicated folder. Links for the software can be found through retailers like Hacktronics. Install Hardware Drivers : Most Willar programmers use either the Silicon Labs CP2102 Go to product viewer dialog for this item. or the Go to product viewer dialog for this item. USB-to-UART bridge.
For CP2102-based devices, you may need to download the Silicon Labs VCP Drivers if Windows 10 does not recognize the device automatically.
Configure COM Ports: For the software to detect the programmer (and move out of "DEMO mode"), the assigned COM port must often be between COM1 and COM9.
Open Device Manager, right-click the programmer under Ports (COM & LPT), select Properties > Port Settings > Advanced, and change the port number if it is higher than 9. Programming Steps
Once the software shows the ONLINE status in green at the bottom of the window, you can proceed with programming:
Select Device: Click the Device button and choose your target chip (e.g., Atmel AT89S52). Load File: Click Load to select your .hex or .bin file.
Burn Chip: Click Program or use the Auto button to perform erase, write, and verify operations in one sequence. Troubleshooting on Windows 10
Unsigned Drivers: If you encounter errors during driver installation, you might need to temporarily disable driver signature enforcement via Windows 10 Startup Settings.
Connection Errors: If the software fails to connect, ensure the programmer is plugged directly into a USB port rather than a hub, and verify that the LED on the hardware blinks when connected. If you're still having trouble, could you tell me: Typo – You may mean:
It looks like you're asking for a review of "Willar Programmer" software for Windows 10 (possibly a new version).
However, after checking major software databases (CNET, Softpedia, Microsoft Store), developer forums (GitHub, Stack Overflow), and general web searches, no widely known or reputable software called "Willar Programmer" exists as of 2026.
Here are the most likely possibilities:
Typo – You may mean:
Very niche / obsolete tool – If "Willar Programmer" is an internal company software, a legacy industrial programmer, or a very old tool, there would be no public reviews.
Potentially unsafe software – Be careful. If you downloaded "Willar Programmer" from an unfamiliar site, it could be adware, a virus, or a renamed copy of open-source software.
