功能说明

dcssr_0.init_i2c_address(0x50)

• 初始化设置DCSSR Unit 的I2C通讯地址

dcssr_0.init_modbus(4, 1, 115200, 8, 1, None)

• 初始化Modbus通讯格式

print(dcssr_0.get_i2c_rgb_led())

• 通过i2c获取RGB的值

print(dcssr_0.get_i2c_ssr_status())

• 通过I2C获取SSR的开关状态

print(dcssr_0.get_i2c_status(0xFE))

• 通过I2C模式获取固件版本

print(dcssr_0.get_modbus_rgb_led())

• 通过Modbus通讯方式获取RGB的值

print(dcssr_0.get_i2c_ssr_status())

• 通过Modbus获取SSR的开关状态

print(dcssr_0.get_modbus_ssr_status())

• 通过Modbus模式获取固件版本

dcssr_0.init_mode(1)

• 设置DCSSR Unit 的通讯模式，I2C或者是Modbus

dcssr_0.set_i2c_address(0x50)

• 设置DCSSR的i2c地址

dcssr_0.set_i2c_rgb_led(50, 50, 50)

• 通过i2c设置RGB值

dcssr_0.set_i2c_ssr_state(1)

• 设置SSR设备的开关状态

dcssr_0.set_modbus_address(0x50)

• 设置DCSSR的i2c地址

dcssr_0.set_modbus_rgb_led(50, 50, 50)

• Modbus设置LED的RGB值

dcssr_0.set_modbus_ssr_state(1)

• Modbus设置SSR的状态开关
