void | GMACD_SetRxCallback (sGmacd *pGmacd, fGmacdTransferCallback fRxCb, gmacQueList_t queIdx) |

Return count in buffer
#define GCIRC_CNT_TO_END | ( | head, | |
tail, | |||
size | |||
) |
Return count up to the end of the buffer. Carefully avoid accessing head and tail more than once, so they can change underneath us without returning inconsistent results

Circular buffer is empty ?
#define GCIRC_INC | ( | headortail, | |
size | |||

Increment head or tail
#define GCIRC_SPACE | ( | head, | |
tail, | |||
size | |||
) | GCIRC_CNT((tail),((head)+1),(size)) |
Return space available, 0..size-1. always leave one free char as a completely full buffer has head == tail, which is the same as empty
#define GCIRC_SPACE_TO_END | ( | head, | |
tail, | |||
size | |||
) |
Return space available up to the end of the buffer
__STATIC_INLINE int fixed_mod | ( | int | a, |
int | b | ||
) |
ISO/IEC 14882:2003(E) - 5.6 Multiplicative operators: The binary / operator yields the quotient, and the binary % operator yields the remainder from the division of the first expression by the second. If the second operand of / or % is zero the behaviour is undefined; otherwise (a/b)*b + ab is equal to a. If both operands are non-negative then the remainder is non-negative; if not, the sign of the remainder is implementation-defined 74).

void GMACD_SetRxCallback | ( | sGmacd * | pGmacd, |
fGmacdTransferCallback | fRxCb, | ||
gmacQueList_t | queIdx | ||
) |
Registers pRxCb callback. Callback will be invoked after the next received frame. When GMAC_Poll() returns GMAC_RX_NO_DATA the application task call GMAC_Set_RxCb() to register pRxCb() callback and enters suspend state. The callback is in charge to resume the task once a new frame has been received. The next time GMAC_Poll() is called, it will be successful.

uint8_t | bThreshold, | ||
gmacQueList_t | queIdx | ||
) |
Register/Clear TX wakeup callback.
When GMACD_Send() returns GMACD_TX_BUSY (all TD busy) the application task calls GMACD_SetTxWakeupCallback() to register fWakeup() callback and enters suspend state. The callback is in charge to resume the task once several TD have been released. The next time GMACD_Send() will be called, it shall be successful.
This function is usually invoked with NULL callback from the TX wakeup callback itself, to unregister. Once the callback has resumed the application task, there is no need to invoke the callback again.

fWakeup | Wakeup callback. |
bThreshold | Number of free TD before wakeup callback invoked. |
