Project Evolution

• Past Projects (Prerequisites): If you've previously used the basic 24MHz 8-channel logic analyzers or simple CP2102 UART bridges, you likely hit bandwidth limits with high-speed SPI or JTAG debugging.
• Feature Upgrade: The SLogic Combo 8 unlocks 80MHz sampling and integrated JTAG/SWD debugging. It bridges the gap between a simple "hobbyist" analyzer and professional MSO scopes.
• Effort/Requirements: Intermediate. Requires basic knowledge of PulseView for analysis or OpenOCD/GDB for debugging.

Virtual Technician & Wiring

• Voltage Warning: Signal inputs are 0-3.6V. Do NOT connect to 5V logic directly to avoid damaging the BL616 chip. Use a level shifter for 5V systems.
  Pin Mapping (SLogic Mode): * CH0 - CH7: Connect to digital signal lines.
• GND: Must be connected to the ground of the Target Device.
• Wiring for DAP/CK-Link: Use the dedicated TCK, TMS, TDI, TDO pins as labeled on the housing for JTAG/SWD connections.

Frequently Asked Questions (FAQ)

• How do I switch between modes on the SLogic Combo 8?
  Press the small hidden button in the "MODE" hole using a SIM ejector pin; the LED color will change.
• Is the SLogic Combo 8 compatible with PulseView?
  Yes, it works with PulseView (Sigrok). Ensure you use the Sipeed-specific driver/fork for full 80MHz support.
• What is the maximum voltage the inputs can handle?
  The maximum safe input voltage is 3.6V. It is not 5V tolerant.
• Does it support 4 UART ports simultaneously?
  Yes, in Red LED mode, it provides 4 virtual COM ports (2x 20Mbps and 2x 1Mbps).
• Can I use it to debug STM32 microcontrollers?
  Yes, switch to Green mode (DAP-Link) to use it with Keil, IAR, or STM32CubeIDE.
• Does it support RISC-V debugging?
  Yes, switch to Yellow mode (CK-Link) for T-Head or other RISC-V core debugging.
• What is the sampling rate in 8-channel mode?
  In 8-channel mode, the typical sampling rate is 40MHz. For 80MHz, use 4 channels.
• What USB cable is required?
  Use a high-quality USB 3.0/3.2 Type-C cable. Standard charging cables may limit bandwidth.
• Does it work on Linux and macOS?
  Yes, it is cross-platform compatible with Windows, Linux, and macOS (using PulseView).
• What is the transmission bandwidth of the device?
  It supports a transmission bandwidth of up to 320Mb/s.
• Are the logic channels isolated?
  No, the channels share a common ground with the USB interface.
• Can it provide power to the target board?
  Yes, it has 3.3V and 5V output pins, but ensure the current draw is within USB limits.
• Why is my PC not recognizing the device?
  Ensure you have installed the correct WinUSB drivers using Zadig or the Sipeed driver package.
• Does it support JTAG debugging?
  Yes, it supports JTAG via the CK-Link and DAP-Link modes.
• What is the VIL and VIH threshold?
  VIH (High) is >2.0V and VIL (Low) is <0.8V.
• How many protocols can it decode?
  It supports over 130 protocols including SPI, I2C, UART, CAN, 1-Wire, and more.
• Can I update the firmware?
  Yes, firmware updates are available via the Sipeed download station and use the "SLogic DFU" mode.
• Is the housing made of plastic or metal?
  The Combo 8 Kit comes in a high-quality black plastic enclosure.
• What is included in the 'Kit' vs the 'Lite' version?
  The Kit version includes the enclosure, premium cables, and test clips, whereas Lite is often the bare board.
• Can it be used as a frequency counter?
  While primarily a logic analyzer, it can measure frequencies up to its Nyquist limit (40MHz).
