When a developer working on BSP wants UART1 with RTS, the following needs to be added in the BSP's include/board.h file: #define PIN_UART1_RTS PIN_UART1_RTS_1 which says that PIN_UART1_RTS_1 -- the first alternative pin with UART1 RTS function -- should be used for the UART1's RTS. There are no alternative pins for PIN_UART2_RTS, therefore a similar definition is not used for PIN_UART2_RTS. However, that is a complication when we want PIN_UART2_RTS to be defined as GPIO, for example: #define PIN_UART2_RTS (GPIO_OUTPUT | PIN_PORTB | PIN2) In such a case, PIN_UART2_RTS is later redefined to the only alternative function from hardware/kinetis_???pinmux.h file. This patch avoids the redefinition of already defined names. We considered renaming PIN_UART2_RTS to PIN_UART2_RTS_1 in the hardware/kinetis_???pinmux.h file, but that is breaking change. We try to avoid breaking change. Signed-off-by: Jiri Vlasak <jvlasak@elektroline.cz> |
