Hi all, I have issue with stm33f767zi and LWiP mqtt. I'm trying to send data over mqtt every 10ms. Data is 400 samples from 3 ADCs represented as cJSON. After sending a few packets Im getting hardfault on tcp_out(), but if I set interval to 100ms eve...
During the project, I need to create equipment that can be updated wirelessly using WiFi. So far, the MCU has been implemented to connect to the router. Is it possible to implement the ota upgrade with the cyw43439chip?
Hi,I'm looking for some suggestions for the implementation of a self-powered and DRD (Dual Role Data) system provided with USB Type-C connector, but without PD support.I found two different solutions:1) Using a configuration channels protection IC (T...
Hi,I am trying to get DMA to work with memory as source and peripheral as dest (UART) and i am not using HAL (this is a learning exercise), but only so far i have managed to get a single character out and the transmission reports as completed (Transf...
I'm learning to port FreeRTOS to my STM32F407, but I'm running into problems with HAL initializing TIM2.After HAL_OK the program is supposed to enable TIM2IRQ via NVIC_EnableIRQ(), but the operation of writing to NVIC->ISER doesn't seem to work.NVIC-...

I've created a project with STM32F407xxx, and using as USBH_CDC with this MCU. STM is working fine but the problem is, the baud rate can not be edited. It is auto by default. How can I keep it fixed at a certain baud rate such as 9600 or 115200? I tr...
Posted on May 26, 2017 at 06:18 Hello, I am using STM32F411RET6 chip to access uSD card with SDIO 4bit. By default it uses polling mode to read/write data with SDIO, such asBSP_SD_ReadBlocks(). The problem is that I want to continuously wri...
How does STM32 dynamically allocate memory ?
Hello everyone,I'm currently facing an issue with migrating an ESP8266 project from EWARM IDE to CUBE IDE for use with the STM32F769I-DISCO board for WiFi connection.When attempting to open the project from the example selector in CUBE MX, I received...
