S32DS操作:
一、新建项目
打开S32DS,FIle–>NEW–> S32DS Application Project选择对应芯片,写入项目名然后下一步
选择对应的SDK,Debugger选带有PE字眼的,点击完成
配置GPIO,双击Components界面下的pin_mux,在弹出的界面里面找到GPIO选项卡,找到想要配置的pin,选择输入或者输出
我这里配置了TPC6为输出模式,然后右键Pin/Signal Selection的PTC6,打开Pin Functional Properties
这里配置PTC6的所有配置:
interrupt status field 中断状态标准位 ——不修改 清晰的标志位
interrupt configuration field 中断触发方式 (ISF)----------失能、DMA、上升沿、下降沿、上升下降沿 、逻辑1、逻辑0。
pin Mux field- ----------IO复用
lock Field---------锁控制
pull enable fieled---------推挽使能
pull select field-----------选择上拉还是下拉
initial value field---------- 默认输出状态
digital filter field ----------数字滤波器
二、生成配置
配置完成后,保存后点击这里生成配置代码,生成的代码会在Grenerated_Code文件夹下
三、代码初始化
S32DS生成的代码只生成了配置,不会想STM32MX一样把我们把初始化写到main里面,所有需要我们自己去写
默认配置下,我们系统时钟用的是高速的内部时钟
在clockman1里面可以查看
这个是S32时钟初始化的代码
CLOCK_SYS_Init(g_clockManConfigsArr,CLOCK_MANAGER_CONFIG_CNT,g_clockManCallbacksArr,CLOCK_MANAGER_CALLBACK_CNT);
CLOCK_SYS_UpdateConfiguration(0U,CLOCK_MANAGER_POLICY_AGREEMENT);
这个是GPIO初始化的代码以及写函数
PINS_DRV_Init(NUM_OF_CONFIGURED_PINS, g_pin_mux_InitConfigArr);
PINS_DRV_WritePin(PTC,6,1); //写PTC6为1
这个是我的main函数
