Usage Instructions
Default Configuration
- The speech recognition module comes with the Factory Firmware pre-installed. It can output corresponding control commands via Type-C and 4PIN interfaces and control corresponding GPIO ports. Please refer to the table below for specific serial port output and control:
- Wiring method (using USB relay as an example):
Updating Firmware via Serial Port
- Open the Firmware Burning Software(make sure there are no Chinese characters in the path)
- Select firmware: \DSTSR-S-formware\for_Dstou_usb_relay_jx_firm\Dstou_usb_relay_release_update.bin
- Update firmware via Type C (disconnect the 4PIN UART wiring), set the DIP switch to the OFF position, plug in the USB cable, and the connected serial port will be displayed in the burning tool.
- Click the "Burn" button
- Set the DIP switch on the board to POWER ON to start downloading. If it doesn't work, repeat the operation. Wait for the download to complete.
- The download process via the 4PIN UART port is the same as the Type C port.
