Hi everyone. I'm currently working on a legacy project that only runs on Zephyr V3.2.0. I have to use the hal_stm32 to get some peripherals running (https://github.com/zephyrproject-rtos/hal_stm32). The latest version of hal_stm32 is not compatible w...
Hello everyone,In my project on STM32 Nucleo-64 with STM32F401RE MCU, I use a timer (TIM11) at 32 Hz in interrupt mode to get some data from sensors. Can I use the RTC (Real-Time Clock) instead of TIM11 to get these data at the same frequency?If yes...
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-...
