WebDec 8, 2010 · Now you could have macros rather than functions, so (if I've got this right - it would be something like): #define bitIsSet (flags,bit) flags bit #define bitSet (flags,bit) flags = bit #define bitClear (flags,bit) flags &= ~bit. You don't have the overhead of calling functions, and the code becomes more readable again. WebFeb 4, 2024 · Each part focuses on a specific integrated circuit (IC) chip. Part 1 – The 74HC595 (currently reading) describes how to add digital outputs using the 74HC595 8-bit serial-in parallel-out (SIPO) shift register IC. Part 2 – The 74HC165 will describe how to add digital inputs using the 74HC165 8-bit parallel-in serial-out (PISO) shift register IC.
