I've done a simply program that receive a character by the UART3 port and it's response is very slow! After sending many times a character the UART3_IRQHandler() works, not instantly as it should be. I'm sure that there is something wrong with FreeRTOS programming. Do you know where the problem could be?</SPAN><BR /><BR /><P><STRONG>Original Attachment has been moved to: <A _jive_internal="true" href="https://community.nxp.com/docs/DOC-337890">app_GPIO_0.c.zip</A></STRONG></P><P><STRONG>Original Attachment has been moved to: <A _jive_internal="true" href="https://community.nxp.com/docs/DOC-337890">Serie_Cfg_0.h.zip</A></STRONG></P><P><STRONG>Original Attachment has been moved to: <A _jive_internal="true" href="https://community.nxp.com/docs/DOC-337890">Serie_Cfg_0.c.zip</A></STRONG></P></BODY></HTML> Wed, 15 Jun 2016 20:25:06 GMT lpcware 2016-06-15T20:25:06Z UART Interrupt with FreeRTOS https://community.nxp.com/t5/LPC-Microcontrollers/UART-Interrupt-with-FreeRTOS/m-p/585670#M21298 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by lucasmf004 on Sat Sep 19 09:25:08 MST 2015</STRONG><BR /><SPAN>Hi everybody, I need some help with the UART interrupt in FreeRTOS with the LPC1769.
