GPIO Input and GPIO Output
GPIO Input
GPIO Output
Description
The General Purpose Input block allows signals from the hardware's GPIO input pins to be used in a schmeatic design. The output pin should typcially be connected to a GPIO Conditioning block. There are 26 selectable inputs to this GPIO block.
The General Purpose Output block routes a signal to the hardware's GPIO output. Each block is linked to one output channel.
Note: The block is only available for DSPs that include GPIO. To configure the hardware's GPIO input and outputs settings, see the processors Register Control Window.
Usage
To use the GPIO Input:
Select the channel desired for sending your signal using the General Purpose Input drop-down control.
- Every enabled input must be connected to an output, else there will be errors on compilation.
- Observe that as you drag more output blocks to your schematic, your number of input channels available in the drop-down decreases.
To use the GPIO Output:
- Use the drop-down to select the hardware GPIO output that is assigned to the block.
- Observe that as you drag more blocks to your schematic, your number of output channels available in the drop-down list decreases.
