Texas Instruments announced the universal asynchronous receiver/transmitters (UART) and controller area network lite (CAN-lite) programmable real-time unit (PRU) daughter cards and software. The UART PRU and CAN-lite PRU daughter cards can be used in evaluation with the AM1x Sitara ARM MPUs or as a standalone reference design. The daughter cards snap into the PRU peripheral connection on the AM1x Sitara ARM MPUs evaluation modules. The TI UART daughter card ($72) and the CAN daughter card ($77) are both available now. The production-quality software code for the daughter cards can be downloaded for free.
