//set one gpo output low
SMBUS_GETGPILEVEL=0x08,//get one gpi input level
SMBUS_SETALLGPOLEVEL=0x0A,//set ALL gpo output LEVEL(0/1)
SMBUS_GETALLGPILEVEL=0x0B,//Get all gpi input LEVEL(0/1)

The function parameter values are shown in the following table:
Address Command Parameter Check
slaveAddress command parameter
false
Parameter means GPO/GPI index values, 1-8.
Then it sends message to M054LDN, and calls SMBWriteByteEx function to control
GPO output electric level. Because M054LDN is a secondary device, GPI input
electric level needs to be actively read by the host. First execute the write function
数
SMBWriteByteEx, then execute read function SMBReadByteEx, to acquire GPI input
electric level information.
