THVD4421: Inquiry on Linux Driver Support for THVD4421RHBR

Ganesh K

Part Number: THVD4421

Tool/software:

I'm looking for information regarding Linux driver support for the THVD4421RHBR(RS232/485/422) . Specifically, I would like to know if there are existing drivers available for this device, particularly in relation to its integration with microprocessors.Additionally, any guidance on developing a driver or resources related to its configuration and use in a Linux environment would be greatly appreciated.

Thank you!

    This device is not directly accessed by software. You connect the transceiver to the UART pins of the microprocessor, so it is the UART module of your MCU that you need a driver for.

    Hi Ganesh,

    Clemens is correct. The RS-485 standard only specifies the electrical characteristics and not any software protocol. As such, this RS-485 device is only on the physical layer and cannot be accessed on a software level. The Lx pins and other logic control pins (SLR, DIR, SHDN, etc.) can be connected to the MCU, where you can choose the protocol to be transmitted over the RS-485 physical layer. 

    Best,

    Ethan
