三、 our new output test program     23017-2port-s-v103.py   display all 32 GPIO status

四、Scratch驅動應用範例 Detail

U1 to U2 i2c 23017  address 21,22

 

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

i222b4 –>  i2c address 22 Port B bit 4 ON/OFF

bit22b01010101 –>  address 22 port B from bit 8 to 1

output  –> 01010101

bit21a01010101 –>  address 21 port A from bit 8 to 1

output  –> 01010101

bit21aoff  –> address 21 Port A all OFF/clear

bit21boff  –> address 21 Port B all OFF/clear
