In my tutorial “Bits and Pins with Kinetis” I showed how to use the BitIO_LDD approach for Bit I/O access. I do not like this LDD (logical device driver) approach for several reasons:
- It requires an extra ‘device handle’ passed to the functions, even if such a device handle is not needed or desired.
- The code efficiency/size is negatively impacted by this.
Luckily, there is a way to hack around this 🙂
