It is +using hardware termed as USART by Atmel. This hardware also supports synchronous +communication and can behave as SPI master, but this is not supported by this +library (I don't require this feature, but implementation is welcomed). + +This part implements, if enabled, whole stack for binding input and output to +stdin and stdout. This is handy during development. You can use `printf` and +`scanf` directly. + +This part can be enabled by `CONFIG_USART` configuration option. This enables +more detailed configuration in sub-menu. + +## Usage + + +## References +### usart_init_async +```C +void usart_init_async(void) +``` + |
