This project implements a loop oscillator circuit and a buried loop coil to detect large metal objects (such as a car). External components are kept to a minimum and oscillator frequency detection is done in software. This project uses a mikromedia plus for STM32 board with shield but any other fast MPU board should work.

Vehicle detection by means of inductive loops in the pavement is not new. This technique has been used for many years and is still in use today.

Applications include sensing cars in left turn lanes to provide advanced green arrow signaling for left turns. Another application is counting cars on a highway for flow control or general road maintenance. Some lesser applications include garage door openers and parking lot security systems.

Exercising The MINI-M4 for STM32

9

A starting set of modules for supporting the many peripheral circuits integrated inside an ARM controller. This example uses the smallest implementation in MikroE’s lineup of ARM boards but has a very powerful microcontroller on-board. The USB interface and built-in boot loader make it all possible without a big expenditure.

Using a Shaft Encoder with MINI-M4 for STM32

0

This example shows how to connect a shaft encoder to a MPU board and provides a state machine decoder that can be used for many useful applications where a rotating dial inputs positional information. This data can be used for display purposes or for converting into analog signal by passing it to the internal DACs.

Non-Blocking Drivers for I2C1 and STMPE610 on Mikromedia Plus for STM32 Board.

0

When the Touch Panel is enabled at the same time as USB, MikroE code hangs up frequently. USB is an essential peripheral and being able to use it together with the LCD/Touch panel is absolutely a must in any application involving this board. This code provides a non-blocking driver while maintaining compatibility with Visual_TFT.
