Functions
void	sense_i3221_one (sense_i3221_cfg_t *m, bool en, uint8_t addr, uint32_t shunt_uohm, uint8_t channels)
	One INA3221 as the SENSE page sets it up before protocol 4.25: the part at addr fitted when en and addr lies in 0x40 to 0x43, each channel in channels (bit 0 CH1) on shunt_uohm, FAST its CH1 when CH1 is one of them.

Detailed Description

The INA3221 map's helpers.

See sense_sched.h. A file of its own so the SENSE page links them without the schedule.

sense_i3221_one()

void sense_i3221_one	(	sense_i3221_cfg_t *	m,
		bool	en,
		uint8_t	addr,
		uint32_t	shunt_uohm,
		uint8_t	channels )

One INA3221 as the SENSE page sets it up before protocol 4.25: the part at addr fitted when en and addr lies in 0x40 to 0x43, each channel in channels (bit 0 CH1) on shunt_uohm, FAST its CH1 when CH1 is one of them.

Anything else in m is cleared.

Parameters

m	The map entry to fill.
en	true when the part is fitted.
addr	I2C address of the part.
shunt_uohm	Shunt resistance, in µΩ, for each channel it has.
channels	Channels to read, bit 0 CH1.
