Expand description

Convenient access to the bit blocks on GPIO ports.

Required Methods§

Source

fn write_pin_range(&self, offset: usize, count: usize, data: u16)

Set count bits on the GPIO port starting from the bit number offset. Other bits are not affected. Uses BSRR register to set/clear individual bits. Bits must fit into 16 bits of the GPIO port.
