Details:
Newer headers povided in the device packs from microchip include a struct for
UARTS that defines a member "BAUD". This conflicts with the use of command
line argument "-DBAUD-9600U". Use of this command line argument to avr-gcc
results in compile error:
/opt/local/bin/avr-gcc -mmcu=atmega4809 -DF_CPU=3333333UL -Os -I.. -I../../
-B/opt/local/avr/packs/mega-1.3.300 -DBAUD=9600UL -c main.c -o main.o
In file included from /opt/local/avr/include/avr/io.h:578,
from main.c:3:
<command-line>: error: expected identifier or '(' before numeric constant
A solution is to not include util/setbaud.h and instead use command line
argument -DBAUDRATE=9600UL with the following usage:
USART0.BAUD = BAUDRATE;
There is a workable solution but the problem of running into the obscure error
message will persist. Maybe replacing BAUD with some other convention will
help.
