Two Wire Communication
The RHSS22-635I2C is a Absolute encoder which acts as a slave and communicate with master micro controller as per the
standard Protocol of I2C. It is also known as Two Wire Communication.
RHSS12-XSPI communicate in 16 Bit of Transmission. After each cycle of communication it is compulsory to toggle CS pin from high to low.
RHSS12-XSPI has a provision of Dual Output first SPI communication and PWM mode of communication 14 Bit and 12 Bit of Resolution respectively.
Number of sensors can be connected in daisy chain mode of 4 wire or (n+3 wire connection). please contact Mr. Pavan Kinariwala(pavankinariwala@gmail.com) for more information on the same.
RHSS12-XSPI will communicate the angle information in below pattern.

Serial Peripheral Interface
The RHSS12-XSPI is a Absolute encoder which acts as a slave and communicate with master micro controller as per the standard Protocol of SPI.
As per standard protocol of SPI RHSS12-XSPI communicate with master protocol when the MOSI pin is active high or 3FFF hex data is sent on the bus and the CS pin need to toggle from low to high for only one clock pulse.
RHSS12-XSPI communicate in 16 Bit of Transmission. After each cycle of communication it is compulsory to toggle CS pin from high to low.
RHSS12-XSPI has a provision of Dual Output first SPI communication and PWM mode of communication 14 Bit and 12 Bit of Resolution respectively.
