Finish MCU bootloader code for 8/16-bit ATMEL AVR XMEGA A1U Microcontroller
Closed - This job posting has been filled and work has been completed.
we have programmed a microcontroller to relay a digital audio signal to three separate digital audio chips.
the code is almost done but need to change the GPIO settings and recompile the code.
here are the directions:
Could you please change the following GPIOs in the ATMEL code...
DAC_SEL2 from 1 to 0
DAC_SEL3 from 1 to 0
... this will allow the CP2114 to boot-up to Index 3, which I've pre-programmed to have our CP2114 settings in it. The other two DAC select GPIOs remain the same.
The GPIOs which change are shown below...
