Hi everyone,I am using Zephyr RTOS as a test on a custom board. I have been trying to communicate with a modem and hoping to receive an OK message whenever I send AT. With an oscilloscope or by connecting it to a USB-Serial cable, I can see that OK i...
Device: STM32F411RE NUCLEOHello, I am having some issues with STM USBD AUDIO library. For some reason I cannot get it to stream audio data to a host device in a proper way.The device is successfully recognized as 2 channel 16 bit microphone by my PC....
Hello Sir,I’ve been dealing with an I2C protocol error for a long time, but unfortunately, neither the solutions online nor the suggestions here have been successful. I've changed sensors multiple times and tried different methods, but the problem re...
I am working on an STM32f767 project with LWIP and MQTT. Everything seemed to work for a while but eventually, I received the following assert: "pbuf_free: p->ref > 0..." which caused it to crash sometimes; but sometimes it will continue to work wit...
Hello, I developped a card around the stm32f401re MCU, and i want to know which one of Pin(s) can show me that my MCU is woke up. It's the first time I use a STM32F401 I never communicated with my MCU, it's for this that I want to know this. Thank yo...
Inquiry about the possibility of opening multiple endpoints to facilitate communication between M7 and M4, so that each specific message triggers a specific response.
I try for the first time to use audio , on my stm32h747i-DISCO board. I have 2 questions 1) the build CM7 is showing the following error Description Resource Path Location Type 'Mode' undeclared (first use in this function) stm32h7xx_hal_msp.c /stm3...
Hi everyone,I am developing a new project with SMT32H7 MCU series, in which I have added the ITTIA DB middleware.I’m encountering an issue while trying to compile my project using a Makefile. The Makefile was auto-generated, and the error I get durin...
In another project using FreeRTOS and LwIP, cubeMX allowed the ability to disable DHCP and set a fixed IP address like 192.168.1.10. But I don't see a way to do that using AZRTOS.
Hi,I work with STM32H753zi , and I used the example SPI_FULLDuplex_ComDMA.I took 2 boards and connected 4 wires between them , as shown in the Readme file.I run the test .In master , the 2 LEDS that indicate Rx and TX completion turn ON.In slave , L...
