Prerequisites
Introduction
1 Relevant Devices
2 Icon Key Identifiers
3 Assignment 1: ADC Conversion with USART Print Application
4 Assignment 2: RTC Interrupts Triggers ADC and USART Print
5 Assignment 3: Power Optimization on I/O Pins
In this assignment, the digital input buffer on I/O pins will be disabled in order to reduce the current consumption. The current consumption will further be reduced when the USART TX pin is configured as a high impedance pin during no data transmission period.
6 Assignment 4: ADC Conversion Using Window Compare Mode
7 Assignment 5: Event System (EVSYS) Used to Replace the RTC Interrupt Handler
In this assignment, the event system with the RTC overflow event signal, instead of the RTC overflow interrupt, will be used to trigger an ADC conversion.
