AS5247 Adapter Board

Operation case

One device SPI mode, unidirectional – 3 wire
4.1
The AS5247 adapter board can be directly connected to an industry standard SPI port of a
microcontroller. The minimum connection requirements for unidirectional communication between
the microcontroller and the AS5247 are MISO, CLK, CSn. In this case the MOSI pin is tied to VDD
wich will result in reading only the 14-bit Angle Register (0x3FFF). See AS5247 datasheet register
table, register 0x3FFF.
