In order to realize the formation of multi-robot control. We uses RFID radio frequency card positioning method and the formation of a ZigBee network with combining sensors, we establish data center to control the formation of four robots. Data center takes STM32 as master, and CC2530 is as a communications platform, each robot is controlled by STM32 master, CC2530 wireless communication module,...

AN3128 Application note STM32 embedded graphic objects/touchscreen library Introduction This library is a firmware package which 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 ...

Almost every microcontroller with integrated flash features firmware readout protection. This is a form of content protection which aims at securing intellectual property (IP) as well as cryptographic keys and algorithms from an adversary. One series of microcontrollers are the STM32 which have recently gained popularity and thus are increasingly under attack. However, no practical experience a...

Aim of this work is the design and realization of a driving system for monitoring and controlling of a BLDC motor with Hall sensors embedded. The realized system is composed by three principal blocks: the control electronic board, the power driving board and the BLDC motor. The first block is based on the STM32 Nucleo development board assembled with the second one, the ST-X-Nucleo-IHM07M1 moto...

Model Predictive Control (MPC) is increasingly being proposed for real time applications and embedded systems. However comparing to PID controller, the implementation of the MPC in miniaturized devices like Field Programmable Gate Arrays (FPGA) and microcontrollers has historically been very small scale due to its complexity in implementation and its computation time requirement. At the same ti...

Three-phase AC-voltage regulatior systems using silicon controlled rectifier (SCR) have been broadly applied in industrial field.This paper introduces a novel design of three-phase AC-voltage regulation trigger circuitry with SCR and STM32 microcontroller, and presents its application in an energysaving design of oil extractor control system. This design employs photoelectric isolation techniqu...

This study about the melism stuff (or melodic substance) i s the continuation of previous ones since several years [for instance 1, 2]. Those studies dealing with a global analysis, this present one will examine in details the processes used by 4 speakers to hightlight F0 prominences at the morphophonological level of the melisms. As the major interest of the study lays upon the repetition patt...
