| AN70630 describes how to combine PSoC® 3 with Cypress nvSRAM to build an event data recorder (EDR), which is finding increasing application in automotive. PSoC 3, with its controller area network connectivity and efficient data transfer using direct memory access, helps free the CPU to execute other tasks. |
Introduction
Systems that rely on electronic subsystems for their functionality use EDRs to store information about system status as it evolves after a critical event occurs. A critical event typically stops the system from functioning.
An EDR, such as the one described in this application note, monitors communication among electronic subsystems (controller area network nodes) and records all or selected information. Moreover, an EDR can store information collected and processed locally from various sensors.
