WebWriting a Character driver We'll look at using the QNX Neutrino io-char library to write a driver for character devices such as serial chipsets that support the RS-232 protocol. Hands-On Exercises In each section of the course, you will have an opportunity to put what you learn into practice. WebFeb 13, 2016 · 1. The master sends the start condition to every connected slave by switching the SDA line from a high voltage level to a low voltage level before switching the SCL line from high to low: 2. The master sends each slave the 7 or 10 bit address of the slave it wants to communicate with, along with the read/write bit: 3.
