- Metrology library version v3.2.00
- The library is able to compute up to 31 harmonic orders
simultaneously
- Functionality in FEATURE_CTRL0 and FEATURE_CTRL1 has been
unified in FEATURE_CTRL0
- FEATURE_CTRL1 was renamed to HARMONIC_CTRL. This register is
used to enable the harmonic computation and for selecting
the desired harmonics orders to be calculated.
- STATE_FLAG.HARMONIC_m_CONF[7:0] field was removed
- HARMONIC output registers increased to 434 registers. The
format changes. The values are not scaled with K_I_x and
K_V_x registers.
- PU (Pull-Up) and OPD (Open-Drain) features removed from
pulse control registers, as these functionalities are not
available while under PWM peripheral control
- Added a protection mechanism to avoid the issue that
sometimes happened when the library was incorrectly
configured to pulse all the energy being applied. The
improper configuration occurred when the configured meter
constants and pulse widths generated a pulse rate not
supported, when applying energies above a threshold. The
effect was that sometimes the library was not working
properly, affecting the accuracy of the measurements.
- In previous version, the metrology library disabled the
watchdogs. Now the watchdog control register is not
written.
