title: Creating new task in FreeRTOS for USART reception
body: <p>I am using EVK1105 development board with AVR Studio 5 as development IDE for my AVR project.
  I am using FreeRTOS in it. I have 3 USART ports on this board. One external module is connected to my AVR32 board via USART-RS232 mode. It sends me continuous serial data to my board on USART0 with 19230 baudrate, 7-databits, odd parity, stopbit-1 and normal-channel mode. I created a new task for this purpose. After each 9 data bytes it sends '\n' and '\r'. So in my task I keep on collecting the 9 databytes in a string buffer and then transmit it on USART1. I am using polling method to collect data from USAR0 which is receiving port. But I am facing problem in receiving data. I don't know if its timing issue or something or the scheduler switches the task while collects the data. But I don't get the required data.</p>
  
  <p>Following are things I have already checked as troubleshooting
  1. Connected my external module to my PC hyper-terminal which gives me perfect result.
  2. Implemented the same thing of using receiving from USART0 and whatever received is transmitted to USART1 as without FreeRTOS. Its works fine.</p>
  
  <p>Please suggest some idea what may be wrong. I am using a queue to communicate between Tx and Rx task to pass the string buffer from USART0 to USART1. Is it problem in handling queue? How can I troubleshoot the queue?</p>
  
  <p>I am using a delay of 50ms in my infinite task loop in Rx Task. Can it create a problem? If I don't use any delay the OS crashes. Please suggest some good practices to create a new task in FreeRTOS so that I will not get any timing issue.</p>
