  • Application: This example code is used for the M480 series microcontroller (MCU) to receive UART data through PDMA.
  • BSP Version: M480 BSP CMSIS V3.05.001
  • Hardware: NuMaker-PFM-M487 Ver3.0
This example code is used to configure UART and PDMA, then transfer data from UART_RX to RAM through PDMA, and also provide complete package flag. Through Scatter-Gather operation mode, the example code will transfer data by looped around two descriptor tables from UART RX to two different destination RAMs in sequence. Complete package flag is used to indicate that the transmission is completed or timeout. This document introduces the example code of UART_RX triggering PDMA configuration, PDMA Scatter-gather mode configuration, descriptor tables configuration, complete package flag and so on.
