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...
Hi, I'm having the following issue with the F103C8 USART DMA.After reset, sometimes the USART DMA Receive doesn't work. It doesn't happen every time, but it happens about once every 10 resets. HAL_UARTEx_ReceiveToIdle_DMA(&huart1, (uint8_t *)RxDataUs...
I'm losing my mind a little, because this seems like it should be a simple task. I have configured my I2C module to enable DMA and interrupts: I can confirm that my call to HAL_I2C_Master_Transmit_DMA returns OK. I can also confirm that the generate...
Hello!I am facing a problem with the STM32H563VIT6 trying to set up MQTT client. I tried to take STM32H573I-DK\Applications\NetXDuo\Nx_MQTT_Client example as a base example on how to do it, but it has not worked for me. The problem I am facing is tha...
I use STM32Cube FW_N6 V1.2.0 to create an FW to run a web server on the DK board. I figured out that I can not talk to the PHY chip to read the PHY ID. I compared the code with another example that ST released and figured out that these codes are mis...
Hello, I am working with an stm32f429_disc board, which has an onboard i3g4250d gyroscope that communicates via SPI. The Zephyr SDK includes a sensor driver for this specific sensor. However, even though I have defined this sensor under the SPI node ...
Hello,I'm using a H743 with the DMA2D device in RegToMem mode. Generally it seems to work for larger images, but I've been trying to fill a small rectangle (5 x 60) pixels, and I was expecting 300 write pulses. Instead, I'm getting 480 pulses (8 x ...
I am simulating messages to be received via CAN on the STM32F0xx series uC. The hardware FIFO does not overflow as I have activated the overflow interrupt and checked the FIFO level, which never exceeds 1. The current implementation consists of a 128...
I've been trying to read the analog temperature sensor on an STM32H723 MCU. Somehow, my readings were invalid. So, I've started debugging and realized that there are possibly faulty macros defined in stm32h7xx_ll_adc.h (HAL v1.11.5). As shown below, ...
Is it possible to re-trigger HAL_TIM_DMABurst_MultiWriteStart() from software? Currently it works only once (the first time) for me. Using TIM1 freq/duty-cycle:HAL_TIM_DMABurst_MultiWriteStart( &htim1, TIM_DMABASE_ARR, // Base = AR...
Hello, I am trying to set up an external flash memory (MX25V1635F) on a Nucleo-U575ZI-Q using SPI.- I managed to simulate a disk using RAM memory, Windows formats it perfectly, which leads me to believe that my USBX configuration is correct.- I also ...
