ODrive CAN Driver(STM32)

Library written by me to control ODrive Motors with STM32 MCU via CAN

Reference

Functions:

void Set_Input_Vel(Axis Axis, float vel, float torqueff);
void Set_TX_Param(int AXIS_ID, int COMMAND_ID, int id_type, int frame_type, int data_length);
void Clear_Errors(Axis Axis);
void Reboot_ODrive(Axis AXIS_ID);
void Set_Controller_Modes(Axis Axis, Control_Mode ControlMode, Input_Mode InputMode);
void Set_Input_Pos(Axis Axis, float Input_Pos, int Vel_FF, int Torque_FF);
void Get_Encoder_Count(Axis Axis);
void Set_Input_Torque(Axis Axis, float torque);
void Get_Bus_Voltage_Current(Axis Axis);
void Get_IQ(Axis Axis);
void Set_Position_Gain(Axis Axis, float pos_gain);
void Set_Vel_Gains(Axis Axis, float Vel_Gain, float Vel_Int_Gain);
void Set_Axis_Node_ID(Axis Axis, uint32_t node_id);
