i have a 24-Channel DPDT Signal Relay Shield + 8 GPIO with IoT Interface and a USB to I2C Converter with Virtual COM Port FT230XS.
i try to use Mobaxterm for serial communication to control the relais but nothing appear on my screen juste a black screen; i try with ubuntu screen /dev/ttyUSB0 and i have the same result.
it’s possible to use Mobaxterm or linux command line with this device (USB to I2C Converter)?
thanks for help
Any application capable of opening a Serial interface port and writing Hex or Decimal formatted byte arrays can be used to communicate with the USB to I2C converter. I recommend reviewing the command set outlined in this guide:
I have the two Ethernet to I2C Converter modules which work well and the USB to I2C Converter with Virtual COM Port FT230XS whose behavior is not stable:
- With AnyI2C: the adapter tells me that the port is open but no communication can be established.
And on the I2C device scan, no device detected:
i have no device detected.
on ubuntu with this command: mdiawara@ubuntu:~$ screen /dev/ttyUSB0 115200
i have juste this:
and can not enter any command after that
Your help is greatly appreciated
thanks for help
Please provide photos of the complete hardware setup.
device on the computer
- one 24-Channel DPDT Signal Relay Shield + 8 GPIO with IoT Interface
- one USB to I2C Converter with Virtual COM Port FT230XS
- hardware setup:
The USB to Serial adapter should appear under COM and LPT ports in your device manager. If it does not then you need to install this driver:
I have already installed the driver and I see the communication port (COM10)
The problem is that neither ANYI2C nor NCD Base sees the device, so no communication.
For now i force COM10 to COM3 (USB serial port) and the ANYI2C work.
