This is a comprehensive guide regarding the FNIRSI 1014D Oscilloscope Firmware . ⚠️ IMPORTANT DISCLAIMER: Firmware updates for budget oscilloscopes like the FNIRSI 1014D carry a risk of "bricking" the device (rendering it unusable). Proceed at your own risk. If your device is working correctly, do not update . There is rarely a need to update unless you are fixing a specific bug or adding a feature supported by custom firmware.
The Ultimate Guide to FNIRSI 1014D Firmware 1. Understanding the Hardware Versions Before attempting any update, you must identify your hardware version. Installing the wrong firmware can damage the device.
Check the Sticker: Look at the sticker on the back of the oscilloscope. Old Version (PCB 1014D): Uses the STM32F103 series microcontroller. Firmware is harder to find and generally no longer updated. New Version (PCB 1014D-1 or V2): Uses the GD32F303 high-performance microcontroller. This is the standard version sold from ~2021 onwards. Inside the Device: If the sticker is unclear, you can remove the four screws on the back. Look at the large square chip in the center. If it says GD32F303 , you have the new version.
2. Current Official Firmware (2023/2024 Update) In late 2023 and 2024, FNIRSI released significant updates for the 1014D (specifically for the GD32 version). Key Features Added/Fixed: fnirsi 1014d firmware
60MHz Bandwidth Limit: The device was originally marketed as 100MHz but realistically performed at ~40-50MHz. Official updates improved analog bandwidth to utilize the full potential, often stabilizing it around 60MHz. XY Mode: Added functionality for Lissajous figures. Waveform Interpolation: Improved sine wave display (sine interpolation vs line). Faster Startup: Optimized boot times.
How to Check Your Current Version
Turn on the device. Tap the "Run/Stop" button or the menu icon. Tap "System Settings" (usually the gear icon or the last tab). Tap "System Info" . Note the version number (e.g., V2.1.3 , V2.2.0 , etc.). This is a comprehensive guide regarding the FNIRSI
3. How to Update Official Firmware Prerequisites:
A FAT32 formatted USB Flash Drive (preferably small capacity, under 32GB). The .hex or .bin firmware file from the manufacturer.
Steps:
Download: Obtain the official firmware file. (Note: FNIRSI does not host a public central repository. Files are usually distributed via the Facebook FNIRSI Group, the AE Official Store chat, or community forums like EEVblog). Prepare USB: Copy the firmware file (usually named something like 1014D_GD32_Vxxx.hex ) to the root directory of the USB drive. Do not put it in a folder. Power Off: Turn off the oscilloscope. Insert USB: Plug the drive into the oscilloscope. Auto-Detect: Turn on the oscilloscope. The device should detect the file on the USB drive automatically. Confirm Update: A prompt will appear on screen asking to update. Tap "Yes" or "Confirm".
Note: If nothing happens, try holding the "Auto" button while powering on, or check that the USB drive is compatible.
