   8. Scratch指令及範例 Detail

U1 to U4 spi 23s17 address 40,42,44,46

U1 to U2 spi 23s17 address 40,42

40 –> 1 42 –> 2 44 –> 3 46 –> 4
48 –> 5 4a –> 6 4c –> 7 4e –> 8

Command “sp”+ “address(1-8)” + “a” +”bit(1 to 8)” for Port A
Command “sp”+ “address(1-8)” + “b” +”bit(1 to 8)” for Port B
Command “bits”+ “address(1-8)” + “a” +”bit(8 to 1)” for Port A
Command “bits”+ “address(1-8)” + “b” +”bit(8 to 1)” for Port B

sp2b7 –> spi address 2 Port B bit 7 ON/OFF
sp3b4 –> spi address 3 Port B bit 4 ON/OFF
bits2b01010101 –> address 2 port B from bit 8 to 11
output –> 01010101
bits2a01010101 –> address 2 port A from bit 8 to 1
output –> 01010101
bits2aoff –> address 2 Port A all OFF/clear
bits2aclr –> address 2 Port A all OFF/clear

Command “sp”+ “address(1-8)” + “a” +”in” for Port A
Command “sp”+ “address(1-8)” + “b” +”in” for Port B
command “sp1bin” initial address 40, Port B as input
broadcast “Update” in Sensing —> Slider ,
you will see “SPI1B-0 ~ SPI1B-7” in the list
