Unable take input from USART - FreeRTOS - AT32UC3A0512

Just trying my hands on FreeRTOS. Following are my setup -

  1. Micro-controller - AT32UC3A0512
  2. Board - EVK1105
  3. Using FreeRTOS
  4. Environment - AVR Studio 5 with ASF latest 2.3 framework

I just created a new project from Example project FreeRTOS. I am checking the USART currently. When run the example project, I am able to transmit characters from my development board to PC through USART but when I type or input something on my PC usart terminal program(using Putty), I am not able to see anything. Can anybody suggest what may be wrong? Or do I need to change the code in the current example code to get input and display on my terminal program for USART?

Thanks...

Solution

  • I got the problem solved. I removed the ISR based code. Just I initialized the gpio module and then initialized the rs_232 mode for usart , rest I used the existing USART.h and usart.c file API to send or receive data in a FreeRTOS task. That solved my problem...
