Declaration

static inline void clock_gpio_init(uint gpio, uint src, float div);

Argument

Description

gpio

The GPIO pin to output the clock to. Valid GPIOs are: 21, 23, 24, 25. These GPIOs are connected to the GPOUT0-3 clock generators.

src

The source clock. See the register field CLOCKS_CLK_GPOUT0_CTRL_AUXSRC for a full list. The list is the same for each GPOUT clock generator.

div

float

The float amount to divide the source clock by. This is useful to not overwhelm the GPIO pin with a fast clock.
