Function/Routine
Name
Description Input Output File Name
OSCOPE_INIT
Defines DIO_7, the VAR pulse
output as a DIO.
N/a n/a Util\oscope.h
OSCOPE_ONE
Set DIO_7, the same pin as the
VARh pulse output, to high.
N/a n/a Util\oscope.h
OSCOPE_TOGGLE
Inverts DIO_7, the same pin as
the VARh pulse output.
N/a n/a Util\oscope.h
OSCOPE_ZERO
Set DIO_7, the same pin as the
VARh pulse output, to low.
N/a n/a Util\oscope.h
pcnt_accumulate()
Accumulates counts from the
previous second.
Void void Meter\pcnt.c
pcnt_init ()
Initialize logic to count output
pulses.
Void void Meter\pcnt.c
pcnt_lcd() Display pulse count on LCD uint8_t select void Meter\pcnt.c
pcnt_start()
Starts plse-counting for a fixed
number of seconds.
Int16_t seconds void Meter\pcnt.c
pcnt_update()
Synchronizes pulse counts with
noninterrupting code.
Void void Meter\pcnt.c
phase_angle_lcd () Displays a V/I phase angle. Uint8_t phase void meter\phase_angle.c
psoft_init ()
Initializes software pulse
outputs.
Void void Meter\psoft.c
psoft_out()
Generates two additional pulse
outputs. Call from ce_busy_isr
void void Meter\psoft.c
psoft_update ()
The inputs are watt hours, as
generated by the CE, and set
the extra pulse generators to
blink at the same rate as CE
pulse outputs, with the same
units. This should be called
each time a new accumulation
interval has data.
int32_t pulse3_in,
int32_t pulse4_in
void Meter\psoft.c
put_char() puts character into CLI buffer uint8_t idata *c none cli\io.c
Read_Trim()
reads the trim value for selected
trim word
enum eTRIM select S08 Meter\io653x.c
rms_I_lcd() Displays current. Uint8_t phase void Meter\rms.c
rms_v_lcd() Displays voltage. Uint8_t phase void Meter\rms.c
RTC_Adjust_Trim()
Safely sets the compensation
variables. Bool clr_cnt,
int32_t value
none IO\rtc_30.c
RTC_Compensation()
Calculates and adjusts the
temperature compensation for
the RTC.
None none IO\rtc_30.c
rtc_isr ()
Interrupt code to adjust clock
each second.
Void void IO\rtc_30.c
RTClk_Read() reads current values of RTC none none IO\rtc_30.c
RTClk_Reset() resets the RTC none none IO\rtc_30.c
RTC_Trim()
Calculates the temperature
compensation using Y_Cals
none int32_t ppb IO\rtc_30.c
RTClk_Write() writes/sets to RTC none none IO\rtc_30.c
s2f()
Returns the floating point CE
units value closest to the
register value. Can lose up to
uint8x_t *register float util\math.c
