3.2 ഹാർഡ്‌വെയർ കണക്ഷൻ

1. പിസിയിലേക്ക് കണക്റ്റുചെയ്യുക: Use the provided USB-B cable to connect the converter to a USB port on your computer. The PWR indicator LED should light up, indicating power.
2. Select Operating Voltage: Use the onboard toggle switch (labeled 5V/3V3) to select the appropriate operating voltage (3.3V or 5V) for your target device. Ensure this matches the voltage requirements of the device you are connecting to prevent damage.
3. ഓപ്പറേറ്റിംഗ് മോഡ് തിരഞ്ഞെടുക്കുക: Configure the DIP switches (S1, S2) on the back of the device to select the desired communication mode. Refer to the table below for mode configurations:

   Table 3.1: Operating Mode Selection

   Mode (M0-M3)	S2	S1	ഫംഗ്ഷൻ
   M0	ഓഫ്	ഓഫ്	UART0 + UART1
   M1	ഓഫ്	ON	UART1 + I2C + SPI
   M2	ON	ഓഫ്	UART1 + I2C + SPI
   M3	ON	ON	UART1 + JTAG

4. Connect Target Device: Use the appropriate jumper wires to connect the converter's interface pins (UART0, UART1, I2C, SPI, JTAG) to your target device according to the selected mode. Pay close attention to pin assignments (VCC, GND, TXD, RXD, SCL, SDA, SCK, MISO, MOSI, CS, TDI, TDO, TCK, TMS, TRST).

4. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

Once the hardware is connected and drivers are installed, you can begin using the converter for communication with your target device.

4.1 ഇൻഡിക്കേറ്റർ ലൈറ്റുകൾ

The converter features several indicator lights to provide feedback on its status:

• PWR: Power indicator, lights up when the USB is connected and voltagഇ കണ്ടെത്തി.
• RXD1: UART1 receiving indicator, lights up when the device sends data back.
• TXD1: UART1 sending indicator, lights up when the USB port sends data.
• RXD0: UART0 receiving indicator, lights up when the device sends data back.
• TXD0: UART0 sending indicator, lights up when the USB port sends data.

4.2 Using UART Interfaces

In M0 mode (UART0 + UART1), both UART channels are active. Use a serial terminal program on your computer to communicate. Configure the baud rate, data bits, parity, and stop bits to match your target device. The converter supports baud rates up to 9Mbps with hardware flow control (CTS/RTS).

4.3 Using I2C and SPI Interfaces

In M1 or M2 mode (UART1 + I2C + SPI), you can utilize the I2C and SPI interfaces. Dedicated software tools or custom scripts are typically used to interact with I2C EEPROMs, OLEDs, sensors, or SPI slave devices. The SPI interface provides two chip select pins (CS0, CS1) for controlling multiple slave devices.

4.4 Using JTAG ഇൻ്റർഫേസ്

In M3 mode (UART1 + JTAG), the JTAG interface is enabled. This is primarily used for debugging and testing microcontrollers or FPGAs. Tools like OpenOCD can be used in conjunction with the JTAG interface. Users should verify compatibility and functionality with their specific JTAG debugging setup.

  • തെറ്റായ വോളിയംtagഇ ലെവൽ: Verify the 3.3V/5V toggle switch is set to match your target device's voltage.
  • തെറ്റായ വയറിംഗ്: ശ്രദ്ധാപൂർവ്വം വീണ്ടുംview your connections between the converter and the target device. Ensure VCC, GND, TXD, RXD, and other protocol-specific pins are correctly matched.
  • Baud Rate Mismatch (UART): Confirm that the baud rate in your serial terminal software matches the baud rate of your target device.
  • ഇൻഡിക്കേറ്റർ ലൈറ്റുകൾ: Observe the RXD/TXD indicator lights. If they are not blinking during data transmission, it indicates a lack of communication.
• Device Not Recognized by OS:
  • Check Device Manager (Windows) or `lsusb`/`dmesg` (Linux) to see if the device is detected.
  • Ensure drivers are correctly installed and the device is not showing any errors.
