今天刚拿到6025的电机,开始初步调电机驱动。这个是我初步得到的数据,以及控制数据 ,具体CAN配置也有。
//CAN初始化
//tsjw:重新同步跳跃时间单元.范围:CAN_SJW_1tq~ CAN_SJW_4tq
//tbs2:时间段2的时间单元. 范围:CAN_BS2_1tq~CAN_BS2_8tq;
//tbs1:时间段1的时间单元. 范围:CAN_BS1_1tq ~CAN_BS1_16tq
//brp :波特率分频器.范围:1~1024; tq=(brp)*tpclk1
//波特率=Fpclk1/((tbs1+1+tbs2+1+1)*brp);
//mode:CAN_Mode_Normal,普通模式;CAN_Mode_LoopBack,回环模式;
//Fpclk1的时钟在初始化的时候设置为36M,如果设置CAN_Mode_Init(CAN_SJW_1tq,CAN_BS2_8tq,CAN_BS1_9tq,4,CAN_Mode_LoopBack);
//则波特率为:36M/((8+9+1)*4)=500Kbps
//返回值:0,初始化OK;
// 其他,初始化失败;
