Sometimes, it makes more sense to control a peripheral with a deterministic, dedicated processor rather than a general purpose ARM core in a TI processor. Applications range from a dedicated monitoring system to a real-time environment where stimulus requires a response from the processor in a known amount of time. This video shows an example of how to use the Programmable Real-time Unit (PRU) core to control a peripheral on any TI processor with a PRU-ICSS or PRU-ICSSG.
