  • ST AN1711 Application Note

    This application note introduces some software techniques for compensating and minimising ST7 ADC errors. The document also provides some general tips on writing ADC software. For a list of related application notes that contain other useful information about ADCs see section 6 on page 39. This document provides some methods of calibrating the ADC. Some ADC errors like Offset and Gain errors can be cancelled using these simple software techniques. Other errors like Differential Linearity Error and Integral Linearity Error are associated with the ADC design and cannot be compensated easily. The example software provided with this application note is explained in brief in section 5 on page 35.

  • ST AN2017 Application Note

    This application note explains the different ways to reset the ST7 Microcontroller, including external reset, internal low voltage detect (LVD) reset, and internal watchdog reset. By selecting different reset sources, the application can be designed more effectively. The document also provides detailed information on the working principle and configuration options of the internal LVD reset.

  • ST AN2030 Application Note

    This document is an application note for the ST72141 chip. It introduces the back EMF detection algorithm of the ST72141 chip. This algorithm uses the on-time of the PWM to detect the back EMF. It solves the problem of the long settling time of the parasitic resonant between the motor inductance and the parasitic capacitance of power devices in the ST72141 sensorless drive system at high speed.

  • ST AN2038 Application Note

  • ST AN2046 Application Note

    This application note describes how to use the “STR71x_Calculation.xls” file which is intended as a tool to assist in the configuration of the STR71x clocks and baud rates. The STR71x microcontroller contains a variety of peripherals running at different frequencies. Some peripherals have a prescaler to adjust their working frequency, but some others don't and need a specific frequency to run correctly. The file “STR71x_Calculation.xls“ calculates all the working frequencies and shows the re- lated register values for each peripheral. Note: This application note doesn’t substitute the fact that it is mandatory to read the refer- ence manual before the use of this tool.

  • ST AN2077 Application Note

    This application note explains how to use STR71x series microcontrollers on-chip Flash to emulate EEPROM.

  • ST AN2078 Application Note

    This document provides an overview and running guide for STR7 in-application programming using UART.

  • ST AN2099 Application Note

    Describes how to connect a Host debugger to a target STR71x board, and provides detailed descriptions of the internal characteristics of the STR71x, connection issues, and solutions

  • ST AN1778 Application Note

    This application note describes how to set up the Multi-ICE debug interface target when accessing it for the first time. It assumes that the ICE tool software has been installed. Ensure that the RealView Debugger software is installed first before installing the Multi-ICE software. The document also describes the Multi-ICE interface and ICE server setup.

  • ST AN1780 Application Note

    This application note explains how to use the STR71x Real Time Clock (RTC) peripheral and demonstrates how to set up the RTC peripheral to keep track of time and date and generate alarm interrupts.

  • ST AN1781 Application Note

    This application note describes how to drive a 4-digit 7-segment display using the STR71x GPIOs

  • ST AN1797 Application Note

  • ST AN1798 Application Note

    This application note describes how to use the Sigma-Delta Analog to Digital Converter (ADC) in the STR71x microcontroller. It describes the Sigma-Delta ADC calibration and linearization technique and shows how to apply a conversion speed-up technique to reduce the conversion time.

  • ST AN1799 Application Note

    The aim of this application note is to show how to scan the 4x4 matrix keypad multiplexed with a four 7-segment display. The software attached to this application note scans the pressed key and displays it on the multiplexed 7- segment LEDs. This application note describes how the interrupt capability of the STR710 device is used to offer a better key scan.

  • ST AN1800 Application Note

    This document presents a standard communication interface between a STR71x microcontroller and a PC using the RS232 protocol through the STR71x BSPI peripheral.
