Caution: Incorrect driver installation can lead to BSOD (Blue Screen of Death) or controller lock-ups. Follow this sequence precisely. Tornado tp microscope driver
The driver will attempt to flash the controller’s firmware. Do not power cycle during this step.
| Parameter | Value | |-----------|-------| | Max Pixel Resolution | 32k x 32k (1.07 Gpixel) | | Dwell Time Range | 100 ns – 10 ms per pixel | | Image Acquisition Modes | Single frame, Tile scan (grid), Line scan, ROI zoom | | External Sync | TTL input/output for EDS/CL/EBIC triggering | | Output Channels | 4 analog (for coil drive), 16-bit DAC | | Input Channels | 2 high-speed (40 MHz), 16-bit ADC | macOS:
For high-resolution scans (e.g., 4096 x 4096 pixels), the default 4 MB buffer may overflow. Open the driver registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TornadoTP\Parameters
Create a DWORD (32-bit) value named BufferSizeMB and set it to 16 (decimal). Reboot for changes to take effect. Linux:
Document ID: TOR-TP-AN-2024-01 Applies to: Tornado TP (Thermionic / Tungsten Filament) & Tornado TPE (Environmental / Low Vacuum) Drivers
The driver includes a hidden configuration utility. Access it via: C:\Program Files\Tornado Instruments\TP Driver\TPConfig.exe
Critical settings to adjust:
| Parameter | Recommended Value | Why? | | :--- | :--- | :--- | | USB Transfer Size | 1024 KB (Max) | Reduces CPU interrupts; prevents dropped frames. | | Scan Rate Buffer | 64 MB | Necessary for high-speed (4 kHz) line scanning. | | PID Update Rate | 50 kHz (for air) / 20 kHz (for liquid) | Faster updates prevent tip crash on soft samples. | | Z-sensor Lowpass Filter | 1.5 kHz | Removes electrical noise without damping real topography. |
