Linux¶
Libtropic support on Linux is implemented with:
HALs for these ports are available in the libtropic/hal/linux/ directory.
See our Linux SPI Tutorials to quickly get started.
SPI and GPIO Linux Userspace API¶
This port uses the SPI and GPIO Linux Userspace API. It was tested on:
Examples for this port are in the examples/linux/spi_devkit directory.
SPI and GPIO Linux Userspace API with native CS¶
Warning
This port is experimental. It can be modified or removed in the next release without notice. As such, no examples are provided.
This port uses the SPI and GPIO Linux Userspace API.
The main difference from the SPI and GPIO Linux Userspace API port is that the GPIO is used only for interrupt handling, as the chip select is handled natively by the SPI driver. The main benefit is that no additional GPIO pin is required and no GPIOs are required at all if interrupts are not used. However, more data are transmitted on each transaction, as this port has no custom control over chip select, meaning it needs to transfer whole buffer on each transaction.
