Serial Port to SPI Design with 8 Slave Device Address
--------------------------------------------------------

Yoy can use design with any device which has basic serial port
You can use Web Serial,Wifi Serial, Bluetooth Serial
All SPI modes supported provided correct polarity clock is used
You can implement design in Dialog Semiconductor SLG46620 20 pin TSSOP


Software Interface
------------------

First byte is Slave select address ie Hex 80 will select CS8
Next Bytes are data bytes.
if Timeout expires then process terminates and circuit waits
for next sequence of bytes starting with address byte.

You can use Real Term to interactively develop your Application Circuit.

This circuit can be use to do DIgtal I/O, Talk to SPI Devices and I2C via SPI_I2C Bridge (CP2120).
