How to send and receive characters and/or packets of data using a UART or USART with Atmel Software Framework and demonstrated on an ARM Cortex board. - Update Device header file LPC177x_8x. Is there any know problem with the CMSIS files that come with MDK-ARM? Could this problem be related somehow to my specific Windows XP, SP3 machine? I am running out of ideas here. 4) Here is another example of code which uses TI microcontroller. I have created a new thread for the UART DMA with normal/high priority and 1024bytes for stack, the behavior is better but still unreliable. c, go to Properties and uncheck the 'Exclude resource from build' box.
