APIs#
This section provides a reference to the Si91x Peripheral API including the functions, data types, and constants provided for various peripherals on the SiWx917™ chipset.
Calendar functions to set or get the current RTC time and date.
Config Timer functions to create timers to count clocks and events, capture events on the GPIOs in input mode, and output modulated signals.
Direct Memory Access functions to transfer data from a source peripheral or memory to a destination peripheral or memory over one or more advanced high-performance buses (AHBs).
Memory LCD functions to access the liquid crystal display (LCD) peripheral on the device.
Sleep Timer functions to access software timers, delays, timekeeping, and date features using a low-frequency real-time clock.
Input-Output Stream functions to perform input/output by creating streams.
Non-volatile Memory functions to access the non-volatile memory (NVM3) driver to maintain key-value pairs in flash memory.
Disable UC Config section providing information on disabling certain peripherals that are enabled by default.
General-Purpose Input-Output functions to set, clear, and toggle pins, program them as input/output pins, and generate interupts including group interrupts.
Generic SPI functions to access input/output (I/O) interfaces to a wide variety of SPI-compatible peripherals on the device.
I2C functions to access the I2C controllers on the device.
Serial Input-Output functions to access the regular GPIO pins and enhanced serial stream processing.
Synchronous Serial Interface functions to access the SSI controllers on the device.
Ultra Low-Power Timer functions to use low-power timers to count clocks, microseconds, milliseconds, seconds, and minutes with both ref clock and system (SoC) clock.
USART functions to access the Universal Synchronous/Asynchronous Receiver/Transmitter (USART) interfaces on the device.
Watchdog Timer functions to generate interrupts on timeout or a system reset on system failure.
