Cutting Optimization Pro is a cutting software used for obtaining optimal cutting layouts for one (1D) and two (2D) dimensional pieces. The software also lets you to define and handle complex products, such as table, desk, cupboard, locker, book shelf ...

Cutting Optimization Pro can be used for cutting rectangular sheets made of glass, wood, metal, plastic, or any other material used by industrial applications.

Cutting Optimization Pro can also be used as cutting software for linear pieces such as bars, pipes, tubes, steel bars, metal profiles, extrusions, tubes, lineal wood boards, etc and other materials.

Calibration Best Practices for KMDF HID Minidrivers on Touch I2C Devices

Optimizing Touch Accuracy: Best Practices for KMDF HID Minidriver Calibration on I2C Devices kmdf hid minidriver for touch i2c device calibration best

In EvtInterruptDpc , read touch data, apply no-op calibration (identity matrix), and submit HID report.

By prioritizing compatibility with Microsoft's built-in frameworks and implementing calibration logic directly in the minidriver (or better yet, in the firmware), you ensure a stable, accurate, and frustration-free touch experience on any Windows device.

If the hardware supports it, read the entire touch state (multiple fingers) in a single I2C burst read rather than multiple small transactions. Implementing the Calibration HID Feature Report Implement a private IOCTL in the KMDF driver:

Because Kernel-Mode Driver Framework (KMDF) and WDM dispatch routines can conflict during power state transitions, Microsoft abstracts registration via MsHidKmdf.sys . This acts as a pass-through driver that communicates directly with HidClass.sys . Your actual device controller functionality sits beneath it as a , pulling raw X/Y register matrices over the physical I2C serial bus.

When packaging the driver, configure the device hardware keys inside the .inf installation script. The parameters below instruct the driver how to scale and map the raw digitization grid:

The typical pipeline:

Windows allows user-space applications or calibration control panels to interact with your driver via . This structure lets software trigger a manual recalibration routine. HID Report Descriptor Fragment

Windows provides an integrated class driver named mshidi2c.sys which implements the Microsoft HID Over I2C Protocol Specification . When a specialized vendor chip requires distinct firmware loading, specific initialization strings, or custom registers, developers write a . This minidriver executes the low-level tasks over the Simple Peripheral Bus (SPB) and routes standardized packages back to the system. Root Causes of Touch Alignment Errors

When deploying image updates across hardware platforms, ensure the appropriate firmware configuration script or compiled binary ( .sys or custom firmware blob) corresponds strictly to the designated ACPI string. Deploying a generic fallback driver breaks coordinates, resulting in compressed, unscalable touch fields. When packaging the driver, configure the device hardware

VOID ProcessTouchData( _In_ PDEVICE_CONTEXT DeviceContext, _In_ PUCHAR RawBuffer ) // Extract raw coordinates from vendor-specific I2C payload structure LONG rawX = (RawBuffer[1] << 8) Use code with caution. Step 3: Formatting the HID Input Report

The for your touch controller chip.

Online manual
  1. Pieces to be optimized are introduced in Parts table. Add data by pressing the + button at the top part of tables.
  2. Pieces to cut from (the sheets) are introduced in Stock table. The Stock is automatically handled. In the case of 1D optimization (pipes, bars, linear pieces) only the Length must be introduced. The other field (Width) must be left empty or set to 0.
  3. Press the button Start. At the end of cutting optimisation the solution will be printed in graphic and text mode. If you are not satisfied with the current solution (optimisation) you may press Start again. You may also increase the Optimization level from menu Settings | Algorithm.
  4. If you are satisfied with the current solution you may print and save it. Then press Accept. Utilized pieces will be removed and the useful one will be added tot the Stock.
