https://community.nxp.com/t5/i-MX-Processors/FreeRTOS-with-UART-in-9-bit-mode/m-p/1609369#M202314 <P>Hello,</P><P>I'm working on a project based on the IMX 1060 and freeRTOS process. This project uses serial communication over UART. This communication is running in 9-bit mode. First byte with flag 1 as address and other bytes as data with flag 0. If I did not use freeRTOS there would be no problem with anything. There I would use the LPUART_SendAddress function for the address and LPUART_WriteBloking for the data. The LPUART_WriteBloking function is not appropriate to use in a task within the RTOS. Although there are LPAURT_RTOS_Send and LPUART_RTOS_Receive functions, but are these functions applicable to 9-bit mode? I couldn't find any information about this anywhere. Can anyone advise me? Thank you.</P> Fri, 03 Mar 2023 17:21:03 GMT masterboy 2023-03-03T17:21:03Z https://community.nxp.com/t5/i-MX-Processors/FreeRTOS-with-UART-in-9-bit-mode/m-p/1609369#M202314 <P>Hello,</P><P>I'm working on a project based on the IMX 1060 and freeRTOS process.

I will report this software request internally.&nbsp;</P> <P>best regards,</P> <P>Mike</P> Fri, 10 Mar 2023 02:17:04 GMT https://community.nxp.com/t5/i-MX-Processors/FreeRTOS-with-UART-in-9-bit-mode/m-p/1612765#M202543 Hui_Ma 2023-03-10T02:17:04Z
