This tutorial is dedicated to students and engineers.  In a previous tutorial, the input capture technique was used for measuring the frequency of a PWM signal. The timer TIM2 was configured for capturing two rising consecutive edges but its resolution is limited to 16 bits. This implies that the two edges are at most separated by 0xFFFF cycles.…

This tutorial is dedicated to students at phelma  in the frame of the first year projects and newbies too with STM32. The Input Capture technique is used to capture a timer value based upon an event on an input pin. The IC features are useful in applications that require frequency (time period) and pulse measurements.   The following equipment is…

Hello,   I enabled etherent and lwip ,tftp on my code. After I got tftp_server.c/.h files, Any body could help me to use this function or I have to do different.  Actually I am upgrading my device firmware. To do that I want to download firmware from a TFTP server and store in user flash.   please help to get this done. any code that I can… (Show more)

Hardware Setup: The board used for this project is STM32F411VE Eval Board. A GPS Module is used which outputs NMEA Sentences over the Tx Line which is received by STM32. A 7 segment MAX7219 Display module is used to display the extracted time. This module communicates to STM32 via SPI interface.  USART to USB module that is used to receive a… (Show more)

“We are trying to develop a USB Host HID application where using the controller STM32F4, and the USB stack library available on the ST website, we are trying to send data/command to an USB HID device. But in the library we downloaded from ST site, the host HID application has examples for mouse and keyboard application only.In case of Mouse and… (Show more)

Hi everybody This tutorial is aimed at helping users to drive a simple rotary wheel encoder. This example was developed using the system workbench for STM32 environment (denoted by sw4stm32 freely downloadable from openstm32.org site. Enjoy.   Presentation and code are attached hereafter.   JC Toussaint Grenoble-INP phelma

Hello  Using multiple devices with the same I2c address on the same bus is theoretically impossible. One solution is the use of bus switch http://www.ti.com/lit/ds/symlink/pca9543a.pdf  The second one is a software implementation attached with this post. It's a draft functional version without acknowledge error management. I plan to be…

This post is targeted at engineers, hobbyists, students, and engineers and provides two complete practical implementations, one based on HAL drivers and the second based on both HAL and LL drivers, for sampling a signal at regular intervals. The following equipment is used -  NUCLEO-L476RG Board and an analog device like ADXL345 accelerometer -…
