Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A project requires a microcontroller to measure the duration of an event using Timer 0. Calculate the register values needed for a 250ms delay using 11.0592 MHz.

💡 Hint: Use the machine cycle calculation initially, then find how many ticks cover 250ms.

Challenge 2 Hard

Using Timer 1 as a counter to count pulses from a sensor is an ongoing project. Draft a simple pseudocode for how you would set it up, including overflow handling.

💡 Hint: Think about using TCON’s overflow flag to trigger alerts or actions.
