Dear my friends,
I have some questions.
I get SDK_2.2_MKL25Z128xxx4 from MCUXpresso Config Tools（SDK builder）, and I find there have too manay uart driver(such as: cmsis_driver_examples\uart\interrupt_transfer\ cmsis_usart_interrupt_transfer.c & driver_examples\uart\interrupt_transfer\uart_interrupt_transfer.c) , both of them are different, So my question is :
1. which driver version I should choose, Why there have two difference uart-driver version for UART( I know ,stm32 uart drivers is only one)
2. in file MKL25Z4.h, I find two type: UART_Type & UART0_Type
#define UART1 ((UART_Type *)UART1_BASE)
#define UART0 ((UART0_Type *)UART0_BASE)
what the difference between the two type, and how to use it. ( UART_Type is used for uart1,uart2 ? UART0_Type is only used for uart0 ?,isn't it ?)
