Notas de aplicación

  • Using Execute, Write/Erase Flash Protection on Stellaris MCUs Using CCS (Rev. A)
    PDF, 1.7 Mb, Revisión: A, Archivo publicado: agosto 15, 2012
    Protection of code and IP in a microcontroller's Flash memory has always been an important consideration for the system designers. StellarisВ® microcontrollers feature a code protection mechanism that enables developers to protect their code and IP in the end application, while providing the flexibility to upgrade the firmware using a boot loader. This application report describes using Flash p

    PDF, 120 Kb, Archivo publicado: jul 7, 2009
    This application note describes how to communicate with the Stellaris serial flash loader application.
  • Using a 9-bit Software UART with Stellaris (AN01280)
    PDF, 301 Kb, Archivo publicado: jul 7, 2009
    This application note describes how to extend the functionality of the standard hardware UART available on StellarisВ® microcontrollers by using the 9-bit UART add-on.
  • Optimizing Code Performance and Size for Stellaris Microcontrollers (AN01265)
    PDF, 161 Kb, Archivo publicado: jul 7, 2009
    This application note provides a summary of factors that affect code performance and size for StellarisВ® microcontrollers and suggestions to improve code performance and size including example code.
  • StellarisВ® LM3S ADC Calibration (AN01282) (Rev. C)
    PDF, 127 Kb, Revisión: C, Archivo publicado: nov 1, 2012
    This application report describes a method for improving the absolute accuracy of the analog-to-digital converters (ADCs) found on StellarisВ® LM3S microcontrollers. Due to inherent gain and offset errors, the absolute accuracy of the ADC is affected. The methods described in this application report can improve the absolute accuracy of the ADC results.
  • Using Stellaris MCUs Internal Flash Memory to Emulate EEPROM (AN01267)
    PDF, 91 Kb, Archivo publicado: jul 7, 2009
    This application note describes how to emulate EEPROM using the internal Flash memory and provides an example application that uses EEPROM emulation drivers.
  • Software UART for Stellaris Microcontrollers (AN01270)
    PDF, 77 Kb, Archivo publicado: jul 7, 2009
    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, Revisión: A, Archivo publicado: enero 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, Archivo publicado: 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, Archivo publicado: 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.
