Can DTM on nRF52840 be controlled by SPI interface?

JPierpont

We currently have a SPI interface between MSP and the Nordic nRF52840. In the DTM documentation it indicates UART is used to command the tests. Is it possible to do this using SPI?j

    Hi,

    Yes, The nRF5x have flexible GPIO mapping, so all pins can be individually mapped to interface blocks for layout flexibility. You can therefore use any free GPIO pin you have on your board for UART(E).

    The nRF52840 have 2 UART(E) Peripherals. The first one can be configured to be used either with or without EasyDMA(either as UARTE0 or UART0), while the second one can only be configured with EasyDMA (UARTE1). The 2 UART(E) Peripherals each have its separate instance. See the Instantiation table here.
