Description:
This module is the 16 IO extension module of the SPI interface, and uses the MCP23S17 chip of MicroChip. The chip is fully functional, each IO can be configured as input or output arbitrarily, and it can be used for color weaving to use pull-up resistors, and configured as input sub IO can enable interrupt function. The IO interface has a strong driving capacity, and the current and current can reach 25mA.
    MCP23S17 is a high-speed SPI interface, up to 10MHz. The chip has 3 address pins and can set 8 different addresses, so 8 modules can be connected through two IIC buses to achieve up to 128 IO extensions.
