This application note looks at implementing a software-based UART which, using general-purpose input/outputs (GPIO), allows the user to overcome hardware limitations or lack of dedicated peripherals. - ADC Oversampling Techniques for Stellaris Microcontrollers (AN01239) (Rev. A)PDF, 95 Kb, Revision: A, Datei veröffentlicht: Jan 8, 2013
Some members of the Stellaris microcontroller family have an analog-to-digital converter (ADC) module. The hardware resolution of the ADC is 10 bits; however, due to noise and other accuracy diminishing factors, the true accuracy is less than 10 bits. This application report provides a software-based oversampling technique, resulting in an improved effective number of bits (ENOB) in the conversion - Implementing RS-232 Flow Control on a Stellaris Microcontroller (AN01255)PDF, 74 Kb, Datei veröffentlicht: Jul 7, 2009
This application note describes how to implement flow control by using the Stellaris GPIO module with its interrupt support. - Clock Fail Detection for Stellaris LM3SX00 MCUs (AN01278)PDF, 194 Kb, Datei veröffentlicht: Jul 7, 2009
The StellarisВ® on-chip clock failure detection circuitry allows a microcontroller to respond appropriately if the main crystal oscillator stops functioning. This capability can be extended to situations in which the crystal oscillator fails due to an open or short circuit.
