2RA生态之R_IOPORT_PortRead()函数与R_IOPORT_PinRead()函数

Posted 2022-05-18 衾许°

函数原型R_IOPORT_PortRead()

fsp_err_t R_IOPORT_PortRead ( ioport_ctrl_t * const p_ctrl, bsp_io_port_t port, ioport_size_t * p_port_value )

 函数原型R_IOPORT_PinRead()

fsp_err_t R_IOPORT_PinRead ( ioport_ctrl_t * const p_ctrl, bsp_io_port_pin_t pin, bsp_io_level_t * p_pin_value )

 示例代码:

ioport_size_t p_port_value_port_15; bsp_io_level_t p_port_value_port_151;

void hal_entry ( void ) /* TODO : add your own code here */ while (1) R_IOPORT_PortRead(&g_ioport_ctrl, BSP_IO_PORT_00 ,&p_port_value_port_15); if (p_port_value_port_15 & 0x8000) R_IOPORT_PinWrite(&g_ioport_ctrl, BSP_IO_PORT_01_PIN_04 , BSP_IO_LEVEL_LOW ); else R_IOPORT_PinWrite(&g_ioport_ctrl, BSP_IO_PORT_01_PIN_04 , BSP_IO_LEVEL_HIGH ); R_IOPORT_PinRead(&g_ioport_ctrl, BSP_IO_PORT_00_PIN_15 ,&p_port_value_port_151); if (p_port_value_port_151) R_IOPORT_PinWrite(&g_ioport_ctrl, BSP_IO_PORT_01_PIN_04 , BSP_IO_LEVEL_LOW ); else

R_IOPORT_PinWrite(&g_ioport_ctrl, BSP_IO_PORT_01_PIN_04 , BSP_IO_LEVEL_HIGH ); #if BSP_TZ_SECURE_BUILD /* Enter non-secure code */ R_BSP_NonSecureEnter(); #endif

 现象结果:当 S2 按下 LED1 灭，反之 LED1 亮
