General Description

Diolan SPI Bus Host Adapter provides a solution for working with SPI and IO facilities by using your computer with USB adapter.

USB-SPI interface can operate as SPI master or SPI slave device. Read our articles about SPI master interface and SPI slave interface for more details. Cheaper version with only SPI master interface support is also available.

SPI Bus Host Adapter supports all 4 SPI modes, which are configured using CPOL and CPHA parameters. With SMP parameter you can configure different phases for MOSI and MISO lines.

SPI bus frequency is configurable in the range from 2 kHz to 12 MHz.

Connect up to 21 different SPI slave devices to single Diolan SPI Bus Host Adapter. Slave select pin allows to choose specific SPI slave device for each transaction.

Connect up to 128 SPI Bus Host Adapters to single PC. Each adapter has unique serial number that can be used to identify it on the USB Bus. You can also set distinct ID number to each adapter in your fixture and use this ID number to identify the adapter from software.
