SPI

transferCancel()

SPI.transferCancel, transferCancel

Since 0.5.0:

Aborts the configured DMA transfer and disables the DMA peripheral’s channel and stream for the selected SPI peripheral for both outgoing and incoming data.

Note: The user specified SPI DMA transfer completion function will still be called to indicate the end of DMA transfer. The user application can check the actual number of bytes received/transmitted by calling available().
