这是LCD1602与msp430之间的通信,其实可以直接从51移植过来,但是一定要在硬件加上拉电阻,要不然是不通不过的,我说的是你用的是5V的LCD-This is the LCD1602 and communication between the MSP430 can in fact be a direct transplant from the 51, but must be coupled with pull-up resistor in the hardware, otherwise it is unreasonable, however, I say is that you use the LCD is 5V
