1RA生态之R_IOPORT_PinWrite()函数

Posted 2022-11-25 衾许°

麻了，最近学校参加个什么立创EDA的训练营，硬要学一个RA的芯片，在这里写一些关于这款芯片的核心板的笔记

芯片类型:RA2E1A72DFL

fsp_err_t R_IOPORT_PinWrite ( ioport_ctrl_t * const p_ctrl, bsp_io_port_pin_t pin, bsp_io_level_t level ) 说明： Sets a pin's output either high or low. Implements ioport_api_t ::pinWrite.

示例程序:

void hal_entry ( void ) /* TODO : add your own code here */ while (1) R_BSP_SoftwareDelay(500, BSP_DELAY_UNITS_MILLISECONDS ); // NOLINT R_IOPORT_PinWrite(&g_ioport_ctrl, BSP_IO_PORT_01_PIN_03 , BSP_IO_LEVEL_LOW ); R_BSP_SoftwareDelay(500, BSP_DELAY_UNITS_MILLISECONDS ); // NOLINT R_IOPORT_PinWrite(&g_ioport_ctrl, BSP_IO_PORT_01_PIN_03 , BSP_IO_LEVEL_HIGH ); #if BSP_TZ_SECURE_BUILD /* Enter non-secure code */ R_BSP_NonSecureEnter(); #endif

 现象为:LED2 每隔 500 毫秒亮灭。
