描述

樹莓派 Raspberry Pi internal 4 Ports USB Hub & SPI 23s17 x2 (32 GPIO) Board

一、產品特色

1. U15 U16：SPI 23s17 16 GPIO x2 23s17 Datasheet

2. U2：USB 4 Ports HUB chipset

3. J1 (JP3)：USB HUB upper port signal input from Rs-Pi

4. J13：Mini USB 5V input for USB Hub, you don’t need plug 5V , the USB Hub already use 5V from Raspberry Pi (P1 pin2), if your USB device need more power, then you can plug-in 5V in this port.

5. J11：RS-Pi V2 GPIO connector (got 4 more GPIO pin)

our new output test program    23s17-2port-s-v103.py   display all 32 GPIO status

二、Scratch驅動應用範例 Detail

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
