Thank's
Thank you for providing a useful library.
I found a small problem.
uc1701WriteDataBlock() uses buffer transfers.
while (iLen) // internal buffer is only 32 bytes
{
if (iLen >= 32)
i = 32;
else
i = iLen;
SPI.transfer(ucBuf, i); -----> the received data is stored in the buffer in-place
ucBuf += i;
iLen -= i;
}
In case of buffer transfers the received data is stored in the buffer in-place (the old data is replaced with the data received).
So destroy ucBuf.
Thank you.
