This application note provides application information for the LIS302DL low-voltage 3-axis digital output linear MEMS accelerometer housed in an LGA package. The LIS302DL is an ultra-compact, low-power 3-axis linear accelerometer that includes a sensing element and an IC interface capable taking information from the sensing element and providing the measured acceleration data to external applications via an I2C/SPI serial interface.

Introduces how to use STLM20 temperature sensor on low-cost microcontrollers to improve temperature sensor resolution

This application note describes the method of defining the system for regulating the speed of the 5 Vdc fan using an ST72651AR6 microcontroller and digital temperature sensor STDS75 or STLM75. The sensor measures the temperature data and communicates this data to the microcontroller. Based on this temperature data, the microcontroller issues a PWM signal with varying duty cycle to the fan for regulating its speed.

The purpose of this application note is to provide the system/hardware engineers enough ground knowledge to start the design of capacitive touch inferface solutions with the S-Touch™ capacitive controller devices. The document highlights the recommended step-by-step procedures to be followed for a successful S-Touch™ design-in: design flow, PCB layout, fabrication, assembly pre- production and production tests. Each topic covered in this document is explained in detail in other application notes.

This document provides the reference code for the operation of the STMPE811 touchscreen controller. The first part describes how to initialize the STMPE811 device, while the second part provides two practical methods to handle the data coming from the device.

This document provides details on the advanced features of the S-Touch® STMPE811 touchscreen controllers, including autonomous operation, FIFO memory, movement tracking, averaging data to optimize noise cancellation, and window tracking.

AN2855 is an application note released by ST, which introduces the single and double click detection functions of FC30, including working principle, pin configuration, entering and exiting single and double click detection mode, entering and exiting power saving mode.

This document provides application information for the LIS331DL low-voltage 3-axis digital output linear MEMS accelerometer. The accelerometer features ultra-compact size, low power consumption, and selectable ±2 g and ±8 g measurement ranges.

This application note describes the LIS331DLM low-voltage 3-axis digital output linear MEMS accelerometer, housed in an LGA package. The LIS331DLM is a high performance, ultra low-power 3-axis linear accelerometer, which belongs to the nano family of MEMS accelerometers, with digital I2C/SPI serial interface standard output. The device features ultra low-power operational modes, which allow advanced power saving and smart sleep to wake functions. The LIS331DLM has dynamically user-selectable full scales of ±2 g /±4 g /±8 g and is capable of measuring acceleration with output data rates from 0.5 Hz to 400 Hz. The self-test capability allows the user to check the functioning of the sensor in the final application. The device can be configured to generate interrupt signals in response to inertial wakeup/free-fall events or based on the position of the device itself. The thresholds and timing of interrupt generators are programmable by the end user on the fly. The LIS331DLM is available in a small, thin plastic land grid array (LGA) package and is guaranteed to operate over an wide temperature range of -40 °C to +85 °C.

AN3108 is an ST application note that describes the STLM75 firmware library for STM32F10x series microcontrollers. This application note introduces the STLM75 interface firmware library, which contains all the features of the STLM75 temperature sensor and provides an example program for using the library.

This is a firmware package that contains a collection of routines, data structures, and macros covering the main features of a graphic library and supporting a HID device to interact with the graphic objects (touchscreen, joystick, and pushbutton). The library is general purpose and can be executed on any CPU, 8/16/32-bit, to guarantee the maximum portability of any architecture or LCD controller, and it provides a graphical user interface (GUI) for any application that operates with a graphical LCD.

This application note describes the methods and techniques for measuring tilt angles from a low-g 3-axis accelerometer. The LIS331DLH 3-axis digital accelerometer is used as an example in this document. Other 3-axis analog or digital accelerometers may also be applied to the tilt angle measurement procedures described here, depending on their respective specifications.
