Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I need 40 us delay. I made my own function using timers, which works on NUCLEO, just using it in main. Now that I put my program my circuit, I moved that SPI part on freertos, but now I have problem, because that delay doesnt work anymore. I would us...
How can they be both "Active" and "superseded" ?! Similarly F1, F2, F3, F4, etc:
Hi all,At a loss.I'm working with a display on a custom board. There isn't much info on the display itself aside from the driver being an ST7701 so I can only assume that it's been initialised correctly. It's an RGB565 display.That said, I get absolu...
how to activate I2CGood morningI'm trying to make a project that requires the I2C1 bus workif I load the compiled project on arduinofrom debug the application crashes because it can't read the EEPROM on RTCI've read various documents but I can't unde...
I have a custom board with a STM32G431CBU3 connected to a TCPP02-M18 for a USB-C power delivery source solution. I follow the ST tutorials for setting up the USBPD and TCPP middlewares in STM32Cube IDE. I'm also able to get trace data out, which I've...
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...
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.
