Harald Welte	c0bd7f0aaa	mode_cardemu: Move GPIO detection to IRQ, use ring buffer for UART RX ... We don't want to call into the bulk of card_emu.c from interrupt context, so let's introduce a ring buffer as a softwre-FIFO between the USART receiving a byte and the processing of that byte in card_emu.c, which is then performed from the main loop outside interrupt context.	2016-02-29 10:13:33 +01:00
Harald Welte	99f62a6def	mode_cardemu: update_fidi just needs to execute ... the actual translation of the Fi/Di values to the divider is already made, we just need to update the USART divider here.	2016-02-29 10:08:49 +01:00
Harald Welte	9dbc46e799	mode_cardemu: Proper enabling/disabling of USART IRQ sources ... we always have to disable all intrerrupts that we don't want to be enabled	2016-02-29 10:05:10 +01:00
