The Allegro ACS71020 power monitoring IC greatly simplifies the addition of power monitoring to many AC powered systems. The sensor may be powered from the same supply as the system’s MCU, eliminating the need for multiple power supplies and expensive digital isolation ICs. The device’s construction includes a copper conduction path that generates a magnetic field proportional to applied current. The magnetic field is sensed differentially to reject errors introduced by common mode fields.
Is a comprehensive collection of register maps and their bitfields, for EEPROM registers and volatile registers. When completed, developer would easily be able to get and set all configurations, and read all measurements. The bitfields are indepedent of protocol used, so both i2c and SPI will work. However, development related to i2c will be prioritized.
Although most of the work has been done, this is an incomplete library and is not intended to be used in its current form. Its concept has only been tested in software, never on an actual hardware platform.
