U1 to U4 i2c 23017 address 20,21,22,23
Command "i2"+ "address(20-27)" + "a" +"bit(1 to 8)"
for Port A
Command "i2"+ "address(20-27)" + "b" +"bit(1 to 8)"
for Port B
Command "bit"+ "address(20-27)" + "a" +"bit(8 to 1)"
for Port A
Command "bit"+ "address(20-27)" + "b" +"bit(8 to 1)"
for Port B
i221a1 --> i2c address 21 Port A bit 1 ON/OFF
i220b7 --> i2c address 20 Port B bit 7 ON/OFF
i222b4 --> i2c address 22 Port B bit 4 ON/OFF
bit22b01010101 --> address 22 port B from bit 8 to 1
output --> 01010101
bit20a01010101 --> address 20 port A from bit 8 to 1
output --> 01010101
bit21aoff --> address 21 Port A all OFF/clear
bit23aclr --> address 23 Port A all OFF/clear
Setting GPIO as input Command "i2"+ "address(1-8)" + "a" +"in" for Port A Command "i2"+ "address(1-8)" + "b" +"in" for Port B Address 20 --> 1 21 --> 2 22-->3 23 -->4 Address 24 --> 5 25 --> 6 26-->7 27 -->8 command "i22bin" initial address 21, Port B as input (1)"i22bin" initial address 21, Port B as input (2) broadcast "Update" (3) in Sensing --> Slider , you will see the " I2C1B-0 ~ I2C1B-7" in the list |
