Bus Type: SPI

Serial Peripheral Interface (SPI)

Clk / MISO / MOSI / CS

Select the channels connected to the raw bus signals.

Warning: DO NOT create duplicate Channel Groups for the serial bus signals! The GoLogic7 software automatically creates a hidden channel group for each signal in the serial bus. If needed, these hidden channel groups can be used to trigger or display the raw signals in the data views.

When project files are opened, the GoLogic7 software automatically deletes channel groups which duplicate the serial bus channels. This avoid potential conflicts between the channel groups and the serial bus definitions.

Mode

Select the SPI Mode.

Use CS for packet framing.

When checked, the CS signal defines where packets start and end.

Invert CS.

When checked, an active-high CS signal indicates packets are active. Normally, the CS signal is active-low.

Width

Enter the bit-width of each data value.

Bit-Order

Select the data value bit-order: LSB or MSB first.

Invert Data

Inverts the data values.

Clk period

Enter the elapsed time from rising edge to rising edge.

Protocol

The SPI bus is a generic bus with no protocol. The Protocol List allows a Custom Protocol to be applied to the bus data.
