Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

The 8051 microcontroller needs to communicate with a sensor that operates at a baud rate of 115200. How would you set up the UART and what value would you calculate for TH1 using an 11.0592 MHz crystal?

💡 Hint: Apply the baud rate formula provided in the theory.

Challenge 2 Hard

Write the ISR for an external interrupt that increments a global counter variable every time the interrupt is triggered, ensuring that the main program can use this counter value.

💡 Hint: Ensure the ISR operates efficiently without introducing delays or issues.
