SPI interrupt example

[jchan12345]

Since sensor.h API in Zephyr does not support reading hw FIFO, I am planning to use SPI driver to read the hw FIFO on received an interrupt when FIFO has data.

Is there any example in Zephyr using SPI with ISR?   I am using the latest NCS V2.1.0 on a nFC5340 device

Thanks,

JC

Check out these samples:

https://github.com/too1/ncs-spi-master-slave-example

https://github.com/simon-iversen/ncs_samples/tree/master/spi_slave_and_master_ncs_v200

NCS v2.0.0 are used in the samples above, so it should not require too much work migrating to NCS v2.1.0

One difference between NCS v2.0.0 and v2.1.0 is that the devicetree label property has been deprecated. You should use node label instead, and use DEVICE_DT_GET to get the device instead of device_get_binding, see https://devzone.nordicsemi.com/support-private/support/297034#permalink=798418.

Best regards,

Hello Simon,

Can PPI be used to establish a pipe from a SPI output to an UART input??   PPI does not need CPU intervention, so it does not require CPU to read SPI and then write to UART.

Thanks,

Can you open new DevZone ticket about this, since it's not related to the initial question (SPI interrupt sample)?

Best regards,

Simon
