General Purpose Input/Output Control Features and Nodes

General purpose input/output (GPIO) control features in high-speed cameras from Emergent Vision Technologies enhance interfacing, control precision, and communication. These functionalities are crucial for optimizing performance across various applications, categorized into input/output configurations, trigger management, encoder integration, and UART communication protocols.

The GPO and GPI features configure inputs and outputs to manage signals effectively, improving camera responsiveness to external triggers for starting and stopping exposure or frames. Trigger features fine-tune the synchronization and timing of these events, including spatial corrections for precise image alignment. Encoder features ensure meticulous adjustment and synchronization of mechanical movements. Universal asynchronous receiver/transmitter (UART) features facilitate robust data transfer, essential for seamless operation and integration within automated processes. Together, these features enable cameras to perform reliably in complex industrial settings.

You can use the features with Emergent's eCapture Pro application. Alternatively, you can use the features with Emergent's eSDK API and the feature nodes. The \EVT\eSDK\Examples\EVT_GPIO directory contains example code that demonstrates how to programmatically use the GPIO features.

Note: Each Emergent camera provides some or all of the following features and nodes, depending on the camera model.
