This is a little improvement of the Hello World example.
I replaced the call of the
helloworld()
by aprintf()
, I think it's more intuitive.I also added a prototype of the
bl_uart_init()
function to make things clearer and explained a little more its parameters.I finally took the liberty to change the baud rate, because with some test I figured out that if the baud rate is too high, some bugged characters are printed. I chose 230 400 because it's a multiple of the standard 9600 and seems to me to be a good compromise, it is fast enough and has no bugged character.
