Yegor Yefremov	60f745a033	cpu/stm32_common: add support for uart_mode routine ... Add support for specifying data bits, stop bits and parity at runtime. Introduce feature periph_uart_modecfg for uart_mode() till all other CPUs implement it. STM32 L1, F1, F2, F4 supports following modes: * 7E1, 7E2 * 7O1, 7O2 * 8N1, 8N2 * 8E1, 8E2 * 8O1, 8O2 STM32 L0, L4, F0, F3, F7 supports following modes: * 6E1, 6E2 * 6O1, 6O2 * 7E1, 7E2 * 7O1, 7O2 * 7N1, 7N2 * 8N1, 8N2 * 8E1, 8E2 * 8O1, 8O2 Use USART_CR1_M1 macro to detect 7-bit support because even inside one family there could be devices that don't support 7-bit mode. So just using a family macro is not enough. As stated in the datasheets for L0, L4, F0, F3, F7 devices, data bits can only be changed when UART is disabled (UE=0). Introduce uart_stop() routine to satisfy this requirement. STM32 UART adds parity to the MSB of a byte to send. The same also applies to the received bytes. As a result this bit must be masked in order to get the pure data. Signed-off-by: Yegor Yefremov <yegorslists@googlemail.com>	2019-01-31 14:15:20 +01:00

MrKevinWeiss	96f8438ea2	cpu/stm32_common/uart: Prevent uart from sending if not initialized ... Due to the stdio getting called after periph_init the uart may send before initialized. This adds a simple check so the uart does not get into a locked-up state.	2018-12-18 10:16:50 +01:00
