I2C Basics
This module begins our discussion of I2C basics by introducing the theory, structure and signalling of the I2C serial communications…
Timing Diagram Basics
Each component you will encounter that communicates over a serial connection, will require understanding the timing of those interactions. Timing…
Bit Masking the 74HC595
In the last module, we went from using massive chunks of code to flip individual bits, to a more elegant…
Bit Shifting the 74HC595
We need to send more than a single bit at a time, and using the previous code would make our…
Boolean and Bitwise Operators
In previous sections, we’ve learned how to convert byte values from decimal to binary to hex and back again. Now…
Bit Banging the 74HC595
Moving bits around with buttons is the introduction to serial communications control, now let’s adapt the techniques we performed manually…
