Challenge Problems
Push your limits with challenges.
Question 1
You are designing a UART communication system with an 11.0592 MHz crystal and need a baud rate of 115200. How would you set TH1 to achieve this, and what might the configuration settings look like in SCON for stop bits?
💡 Hint: Remember the relationship between oscillator frequency and baud rate to find TH1.
Question 2
Explain the impact of changing stop bits from 1 to 2 in a data transmission scenario with high noise levels. What would be the practical effects?
💡 Hint: Consider how redundancy might be beneficial in adverse conditions.
