use n23s17-cs0.py   test 32 GPIO output

       new test program    23s17-2port-v3.py  demo

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

1. JP23  GA0 ~ GA7   U13 Port A       JP24 AA0 ~ AA7     U13 Port B

2. JP25  BA0 ~ BA7   U14 Port A        JP26 GB0 ~ BG7     U14 Port B

3 R61,R62,R63  ( for U13 Address select A0,A1,A2 )

4. R64,R65,R66 ( for  U14 Address select  A0,A1,A2)

5. U13 (21)  23017 -1  Port A,B           

6. U14 (22)   23017-2 Port A,B

7. pin out 2X10 ,  

Bank A(1-10)  GPIO (0,1,2,3,4,5,6,7,GND, INTA) 

   Bank B (1-10)  GPIO (0,1,2,3,4,5,6,7,GND, INTB) 

   A0, A1, A2 address 

 *  right side GND low - 0      * left side Vcc High - 1

   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
