Description
This TI design provides a reference solution (firmware and test platform) for two different industrial IO functions related to motion control: High Speed Counter (HSC) and Pulse Train Output (PTO). The design is based on a microcontroller platform that is suitable for use in industrial applications where high availability and/or functional safety are also important requirements.
Features
- High speed (up to 400KHz) 32-bit HSC counter with two counter input pins, four auxiliary input pins, two input capture registers, and two compare output pins
- PTO generates output pulse trains and trapezoidal profiles up to 100KHz with 9.1ns resolution
- Count/Dir, Clockwise/Counter Clockwise, and Quadrature Modes
- Reduces CPU load and interrupt latency requirements by operating autonomously on the N2HET Timing Coprocessor
- Reduces system cost by replacing FPGA or ASIC
- Includes N2HET firmware and test platform, as well as host CPU driver functions
