Functions
void	lpc_pconp (lpc_pconp_t peripheral, bool on)
void	lpc_pclk (lpc_pclk_t peripheral, clkdiv_t divider)

Detailed Description

This file provides LPC peripheral numbers according to LPC17xx datasheet.

Function Documentation

void lpc_pclk	(	lpc_pclk_t	peripheral,
		clkdiv_t	divider
	)

Sets the peripheral clock divider.

Parameters

peripheral

The peripheral type.

See also

lpc_pclk_t

Parameters

divider

The divider type

Note

The reset value for all peripherals is clkdiv_4

This is a quick and dirty trick to use uint64_t such that we don't have to use if/else statements to pick either PCLKSEL0 or PCLKSEL1 register.

void lpc_pconp	(	lpc_pconp_t	peripheral,
		bool	on
	)

Powers ON or powers OFF the peripheral

Parameters

peripheral

The peripheral type.

lpc_pconp_t

Parameters

on	If true, peripheral is turned on, otherwise turned off
