Guide on Updating the Firmware of LE-3500/LE-2500 (version 1.04)

LINEEYE has released the latest firmware (ver1.04) of LE-3500/2500.
The latest firmware strengthens the BERT function and supports the new expansion kit "OP-SB5GL".
To use "OP-SB5GL", users should have the firmware ver1.04.

[ Outline ]

The PC link software “LE-PC300G" cannot be used with the CAN/LIN optional expansion kit(OP-SB7GX) for LE-2500/LE-3500. This PC link software “LE-PC7GX" captures CAN/LIN data into PC measured by the CAN/ LIN optional expansion kit for LE-2500/LE-3500. It also has other functions, such as displaying the specific data at real time (watch data function), maximum 16GB recording function, search function, and text conversion function.

[ Update Information ]

  1. Strengthen the BERT(Bit Error Rate Test)function
    Add the function which makes the external triger output active and tells the external device about the error when finding the error bit. The active output will be back to normal when stoping the measurement.

  2. Support the new expansion kit "OP-SB5GL"
    Add the settings for "OP-SB5GL" in the "INTERFACE" setting menu.

    ["INTERFACE" setting now]
      ["INTERFACE" setting before]

    Firmware(V1.04) Firmware(V1.03)or before
    5.0V/3.3V/NO PULL-UP
    *: If using "OP-SB5G" with firmware (V1.04), 2.5V, 1.8V on "LEVEL" and CMOS on "OUTPUT" are invalid.

  3. Other improvements
    • Add the speed of 50Kbps, 200Kbps, 417Kbps for I2C master simulation.
    • Correct the bug of incomplete bit in the SPI slave simulation.
    • Change the beginning point to start the SPI slave simulation repeat mode as CS falling.
    • Add the inter lock for starting measurement when TTL/IrDA pots are not connected.
    • Strengthen the self-check function.
    • Correct the miner bug of firmware loader.
