5 years ago 啊，我看错了，前面还有一句eMode = MB_REG_WRITE;限定了读写方向。 可是这样的写法并不是太好，逻辑上不直观

库主是否实机运行过，在移植的过程中，发现代码有多处bug，如操作holding register时（eMBMasterRegHoldingCB函数）的读写方向
switch (eMode) { / read current register values from the protocol stack. / case MB_REG_READ: while (usNRegs > 0) { pucRegBuffer++ = (UCHAR) (pusRegHoldingBuf[iRegIndex] >> 8); pucRegBuffer++ = (UCHAR) (pusRegHoldingBuf[iRegIndex] & 0xFF); iRegIndex++; usNRegs--; } break; / write current register values with new values from the protocol stack. / case MB_REG_WRITE: while (usNRegs > 0) { pusRegHoldingBuf[iRegIndex] = pucRegBuffer++ << 8; pusRegHoldingBuf[iRegIndex] |= pucRegBuffer++; iRegIndex++; usNRegs--; } break; }
