Configuring the network interfaces on Gentoo
April 30th, 2010
No comments
On Gentoo the main portion of the network configuration will be done inside the configuration file /etc/conf.d/net.
For example, to configure the IP address and netmask for the eth0 interface you should add the following line to the /etc/conf.d/net file:
config_eth0 {"192.168.0.1 netmask 255.255.255.0"}

My U[S]ART implementation
My USART software is based on the ATMEL application note AVR306 : Using the AVR® UART in C.
The original source code of the application note was changed to support receiver error and to support some of the capabilities of the avr UART interface databit (5..8 ), stop bit (1-2) and parity check (none, odd and even).

UART Data Register Empty Interrupt
As described the USART can generate interrupt if the data register is empty. The interrupt could be enabled setting the Data Register Empty Interrupt Enable(UDRIE0) .
The USART Data Register Empty ISR will be executed until the UDRE0 is set (if the global interrupts are enabled).
