ATXMEGA - XMEGA small program in C -- 2

Looking for a freelance that can write a small program for an ATXMEGA32A4U using the C language (Atmel Studio 7 + GCC Compiler [login to view URL]).

Program tasks:

a) configure pins:


PB.3 = INPUT, internal pull-up ON

PC.0 = INPUT, internal pull-up OFF

PC.1 = OUTPUT, starts LOW

PC.2 = SERIAL PORT IN: 1,5Mbps, 8N1

PC.3 = INPUT, internal pull-up ON

PC.4 = OUTPUT, starts LOW

PC.5 = INPUT, internal pull-up ON

PC.6 = INPUT, internal pull-up ON

PC.7 = OUTPUT, starts LOW

* USART setup: [login to view URL]

b) set the clock source:


verify if pin PB.3 is HIGH then

* configure the clock source as "Crystal" (8Mhz) and the PLL as 4x (resulting in 32Mhz to the CPU)

* configure PC.4 as clock output (8Mhz)

if PB.3 is LOW then

* configure the clock source as "External clock, on XTAL 1 pin" (8Mhz) and the PLL as 4x (resulting in 32Mhz to the CPU)

c) main task (in looping):


c.1) Configure the DMA to store each byte received on a buffer, the buffer size must be 3072 bytes and start the DMA channel;

c.2) Wait until PC.0 goes HIGH; (a simple WHILE here);

c.3) Set PC.1 as LOW;

c.4) Wait 20ms;

c.5) Set PC.1 as HIGH;

c.6) Goto "c.1".

I have experience working with armed MCUs, mega and UC3. I can get your project done, even without hardware (you would have to test in device). Which peripheral should be read using DMA? It's not specified.
