17.2.1 Metrology Engine initialization
17.2.2 Metrology Engine interrupt handler
17.2.3 Metrology Engine set ranges
The EM773 Metrology Engine is available on part EM773 only.
The following seven interfaces of the metrology firmware are exposed to the user
application:
This interface must be called by the application software before the metrology engine can
be used.
This interface configures the metrology engine with the proper settings based on the given
AHB system frequency and mains frequency.
The user application must add the metrology engine interrupt handler to the interrupt
vector table. The driver interrupt handler takes appropriate action according the measured
data and the configured ranges.
This interface must be called by the application software after the metrology engine is
initialized and before the metrology engine is started.
This interface sets the ranges for the voltage input and the current inputs.
The ranges are:
1. metrology engine initialization
2. metrology engine interrupt handler
3. metrology engine set ranges
4. metrology engine start
5. metrology engine stop
6. metrology engine read data
7. metrology engine get gain channel
