There is no locking in I2C implementation. It is an issue if there are several I2C devices and parallel processes. Every I2C read operation contains two independent syscalls. I suggest calling "fcntl.flock". Unfortunately, SMBus package does not provide direct access to I2C file descriptor. Can we use SMBus2 package?
