Register reads and writes are implemented using a small subset of the more general I2C protocol, which consists of an arbitrary number of multi-byte read and/or write messages in a single transaction to one device. python-periphery supports I2C in this sense, which allows interfacing with a wider variety of I2C devices than just the ones that implement a register map. For example, you may want to read/write multiple bytes from an EEPROM in one transaction.
It would be possible to add convenience read()/write() wrapper functions, though.
Thank you very much for responding!

Hello, your library looks really cool. However I was trying to use it for I2C and could not understand the logic behind that code. There are 3 entities involved in I2C operations: the device address, the register within that device, and the value that we want to write or read to the register.
How do you accomplish a writing of value into a register? and how do you read the value from a register?
Thank you! -Itay
