I want to know if there is already a library for the Modbus RTU protocol for S32K344. If anyone has nan example it would help me a lot. Greetings to all.</P> Sat, 11 Oct 2025 08:55:10 GMT https://community.nxp.com/t5/S32K/Modbus-RTU/m-p/2184258#M53428 jkx 2025-10-11T08:55:10Z https://community.nxp.com/t5/S32K/Modbus-RTU/m-p/2184516#M53445 <P>Hi&nbsp;<a href="https://community.nxp.com/t5/user/viewprofilepage/user-id/255716">@jkx</a>&nbsp;</P> <P>NXP doesn’t provide an official Modbus stack for the S32K344, but the MCU is capable of supporting Modbus RTU or TCP.
