Added Kconfig pin config chooser for nucleo-l432kc USARTs. #11

wingunder · 2019-12-26T22:22:46Z

The USART pins were hard-coded for the nucleo-l432kc. This patch makes
these pins configurable via menuconfig.

The USART pins were hard-coded for the nucleo-l432kc. This patch makes these pins configurable via menuconfig.

Author: Gregory Nutt <gnutt@nuttx.org> boards/arm/stm32l4/nucleo-l432kc/Kconfig: Correct use of spaces instead of TABs in Kconfig file. Author: Pieter du Preez <wingunder@users.noreply.github.com> Added Kconfig pin config chooser for nucleo-l432kc USARTs. (#11) The USART pins were hard-coded for the nucleo-l432kc. This patch makes these pins configurable via menuconfig.
