Hi,

The tasks refer to the peripheral registers. These registers can be written as suggested by Turbo J above, to trigger certain tasks. Tasks will usually trigger events (event registers being set), indicating that something have happened and needs attention.

If you are using the SDK, you can configure the drivers to use EasyDMA, without having to touch the registers. In SDK 12.3.0 you can enable EasyDMA on the SPI peripheral by setting the config SPIx_USE_EASY_DMA to 1.

Best regards,
Jørgen

RTFM:

NRF_SPIM0->TASKS_START=1;

You want to look at example code that is shipped with the NRF SDK.
