Introduction

8.2 Framing and CRC (C)

uint16_t crc16_ccitt(const uint8_t *data, size_t len) 
    uint16_t crc = 0xFFFF;
    for (size_t i = 0; i < len; ++i) 
        crc ^= (uint16_t)data[i] << 8;
        for (int j = 0; j < 8; ++j)
            crc = (crc & 0x8000) ? (crc << 1) ^ 0x1021 : crc << 1;

Kernel-space driver (Linux): for serial-over-USB high-performance and device node exposure (/dev/fs-sm100X)
User-space libusb reference: portable across Windows/macOS/Linux for control apps and firmware updater

User-Mode Library (API):
BYTE buffer[1024];
DWORD bytesReturned;
DeviceIoControl(hDevice, FS_SM100_IOCTL_GET_DATA, NULL, 0,
buffer, sizeof(buffer), &bytesReturned, NULL);

• Right-click the Start button and select Device Manager.
• Look for the category "Human Interface Devices".
• You should see an entry named "HID-compliant game controller".
• Right-click it and select "Properties" -> check the "HID-compliant controller" box to see if it registers inputs.
