Hi 志權 ,
Could you tell us which chip or board you are used?
And where the CAN2_SetAcceptance Mask from?
For the convenience of solving the question, it is best for you to paste you 9 ERR_NOTALAIL.
Best regards!

Hi ,
The following is the API definition:
LDD_TError CAN_SetAcceptanceMask(LDD_TDeviceData *DeviceDataPtr, LDD_CAN_TMBIndex BufferIdx, LDD_CAN_TAccMask AccMask);
and below is some description for parameters as well as the return value.
** | @param | |
** | DeviceDataPtr - Device data structure | |
** | pointer returned by [Init] method. | |
** | @param | |
** | BufferIdx | - Index for Acceptance Mask |
** | Message Buffer. | |
** | @param | |
** | AccMask | - 11-bit Mask could be selected for |
** | a standard frame or 29-bit for an extended | |
** | frame. | |
** | @return | |
** | - Error code, possible codes: | |
** | ERR_OK - OK | |
** | ERR_SPEED - This device does not work in | |
** | the active clock configuration | |
** | ERR_PARAM_RANGE - Value of buffer index is | |
** | out of range. | |
** | ERR_NOTAVAIL - Acceptance mask isn't | |
** | possible change when CAN component is | |
** | running, component must be disabled or | |
** | switched to freeze mode. |
So maybe you call this API when CAN is running, please disable it or put it into freeze mode before calling this function.
Hope that helps,
B.R
