This is an input-only gpio driver for use with 74x165 style parallel-input shift registers, (using SPI peripheral) The user can choose to either use cs-gpios of spi or load-gpios for connecting to the SH/LD pin of the shift register. The difference is that cs-gpios will keep the input latch enabled while idle, and load-gpios will instead pulse the SH/LD signal before the register content is shifted. In both cases the gpio should be configured GPIO_ACTIVE_HIGH. |
