An introduction to GPIO Settings

Working with microcontrollers means managing GPIO pins at some point. Many configurations have been developed for modern microcontrollers which can lead to some “fancy” terms that may confuse programmers. Its important to understand all of this to avoid confusion and errors while...

PIC18 Q10 Product Family – PIC® MCUs for Closed-loop Control

Real-time control systems usually are closed-loop control systems where one has a tight time window to gather data, process that data, and update the system. If the time window is missed, then the stability of the system is degraded. This reduced control can be catastrophic to some...
