A few small fixes for the rf22 to satisfy klocwork.
* Converted malloc's to new's to be more C++'ish and since
malloc return were not checked.
* Initialize data, buf, and _lastInterruptFlags
* Up'ed RF22_MAX_MESSAGE_LEN to 64.
Reason:
void RF22::sendNextFragment()
{
if (_txBufSentIndex < _bufLen)
{
// Some left to send?
uint8_t len = _bufLen - _txBufSentIndex;
// But dont send too much
if (len > (RF22_FIFO_SIZE - RF22_TXFFAEM_THRESHOLD - 1))
len = (RF22_FIFO_SIZE - RF22_TXFFAEM_THRESHOLD - 1);
spiBurstWrite(RF22_REG_7F_FIFO_ACCESS, _buf + _txBufSentIndex, len);
_txBufSentIndex += len;
}
}
RF22_FIFO_SIZE = 64
RF22_TXFFAEM_THRESHOLD = 4
RF22_MAX_MESSAGE_LEN = 50
_buf[RF22_MAX_MESSAGE_LEN]
Length of _buf *was* 50, so if the 'But dont send too much' above
was to happen, the length is set to 63, which overruns
_buf[RF22_MAX_MESSAGE_LEN]
