TMS570LS1227: how to interface an external device based on HDLC over RS485

Part Number: TMS570LS1227

I'm currently using a TMB570 MCU. I need to interface and external device through RS485, using the HDLC protocol. Is there any transceiver from Texas Instrument that could help me out? Which would be the best solution?

    Hello Fermat,

    There is some information on RS485 transceivers and EVM located here www.ti.com/.../RS485-FL-DPLX-EVM. Specifically, there is a list of transceivers towards the bottom of the page with different levels of support for full duplex and different baud rates. I would expect that these could be used in combination with Hercules but it was unclear to me what type of interface they require. Hercules can offer SPI, SCI, I2C, CAN, etc.

    In regard to the HDLC protocol, we don't have any supporting examples for this protocol and any protocol specific drivers would have to be custom made for your application.
