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
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.
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.
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.
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.
This document presents a standard communication interface between a STR71x microcontroller and a PC using the RS232 protocol through the STR71x BSPI peripheral.
The aim of this application note is to present a practical example of communication using the BSPI peripheral of the STR71x between a STR71x microcontroller and a M25P10-A SPI Serial Flash memory. It shows an easy way of communicating between the STR71x BSPI interface and the M25P10-A serial flash memory from STMicroelectronics, performing write and read operations.
This paper describes the sensorless control and back electromotive force (BEMF) sampling methods for brushless DC motors, as well as the capability of ST7MC in implementing these topologies. The advantages and drawbacks of these topologies are also discussed.
This application note describes a 3-phase synchronous permanent magnet motor control software library developed for the ST7MC drive with sinusoidal waveform. The ST7MC microcontroller contains a peripheral dedicated to 3-phase brushless motor control, making it suitable for AC induction motors and permanent magnet DC/AC motors (PMDC/PMAC, also called BLDC). The library described here is made of several C modules that contain a set of convenient functions for the generation of the sinusoidal waveform, the synchronization mechanism and closed loop control of PMAC induction motors and is compatible with both COSMIC (www.cosmic-software.com) and METROWERKS (www.metrowerks.com) compilers.
This application note describes how to migrate designs from the uPSD3200 series to the uPSD3400 series, including pin definitions, SFRs, and interrupt vectors.
