CAN_FilterInit †

ヘッダ宣言 †

関数プロトタイプ †

void CAN_FilterInit(CAN_FilterInitTypeDef* CAN_FilterInitStruct)

動作 †

• CAN_FilterInitStruct構造体のパラメータに従ってCAN周辺回路を初期化します。

引数 †

• CAN_FilterInitStruct tm32f10x_can.hファイルで定義されている構造体です。

  typedef struct
  {
  uint_t8 CAN_FilterNumber;
  uint_t8 CAN_FilterMode;
  uint_t8 CAN_FilterScale;
  uint_t16 CAN_FilterIdHigh;
  uint_t16 CAN_FilterIdLow;
  uint_t16 CAN_FilterMaskIdHigh;
  uint_t16 CAN_FilterMaskIdLow;
  uint_t16 CAN_FilterFIFOAssignment;
  FunctionalState CAN_FilterActivation;
  } CAN_FilterInitTypeDef;

  • CAN_FilterNumber CAN_FilterNumber selects the filter which will be initialized. It ranges from 0 to 13.

|CAN_FilterMode Description CAN_FilterMode_IdMask id/mask mode CAN_FilterMode_IdList identifier list mode

• CAN_FilterMode CAN_FilterScale Description CAN_FilterScale_Two16bit Two 16-bit filters CAN_FilterScale_One32bit One 32-bit filter
• CAN_FilterScale CAN_FilterIdHigh is used to select the filter identification number (MSBs for a 32-bit configuration, first one for a 16-bit configuration). 0x0000 to 0xFFFF
• CAN_FilterIdHigh CAN_FilterIdLow is used to select the filter identification number (LSBs for a 32-bit configuration, second one for a 16-bit configuration).
• CAN_FilterIdLow 0x0000 to 0xFFFF
• CAN_FilterMaskIdHigh CAN_FilterMaskIdHigh is used to select the filter mask number or identification number, according to the mode (MSBs for a 32-bit configuration, first one for a 16-bit configuration). It ranges from 0x0000 to 0xFFFF.
• CAN_FilterMaskIdLow CAN_FilterMaskIdLow CAN_FilterMaskIdLow is used to select the filter mask number or identification number, according to the mode (LSBs for a 32-bit configuration, second one for a 16-bit configuration). It ranges from 0x0000 to 0xFFFF.
• CAN_FilterFIFOAssignment CAN_FilterFIFO Description CAN_FilterFIFO0 Filter FIFO 0 assignment for filter x CAN_FilterFIFO1 Filter FIFO 1assignment for filter x
• FunctionalState CAN_FilterActivation CAN_FilterActivation CAN_FilterActivation enables or disables the filter. It can be set either to ENABLE or DISABLE.

戻り値 †

• 無し
