互補輸出 死區 除錯存在問題
使用的是tim1 ch1 ch1n , 目前的問題就是波形的前後死區時間不一樣,根據示波器的測量得知,前面的死區是後面的兩倍。
根據官方手冊可知
**配置如下
tim1_oc.instance = tim;
tim1_oc.init.clockdivision = tim_clockdivision_div1;
tim1_oc.init.prescaler = tim_prescaler - 1; // 1us
tim1_oc.init.countermode = tim_countermode_up;
tim1_oc.init.period = tim_period - 1; // 50us
tim1_oc.init.autoreloadpreload = tim_autoreload_preload_disable;
hal_tim_oc_init(&tim1_oc);
sconfigoc.ocmode = tim_ocmode_active;
sconfigoc.pulse = 0 ;
sconfigoc.ocpolarity = tim_ocpolarity_low;
sconfigoc.ocidlestate = tim_ocidlestate_reset;
sconfigoc.ocnpolarity = tim_ocnpolarity_high;
sconfigoc.ocnidlestate = tim_ocnidlestate_reset;
sconfigoc.ocfastmode = tim_ocfast_disable;

互補輸出 死區剎車 這一部分 主要是初始化3個結構體,包括時基結構體 輸出比較結構體和死區配置結構體,要對照前一篇部落格和中文參考手冊中的暫存器說明來仔細看,如下 bsp advancetim.c include bsp advancetim.h static void advance tim gp...
