I'm having problems getting an ADC value from the STM32F777IIK chip we have embedded in one of our boards.I have used a digital GPIO application and have confirmed that the ADC pin (PC0) is connected from the chip to the headers that is good.I have u...
I'm new to STM32 processors. I'm learning on a Nucleo F103rb board. I was able to receive a single character through UART in polling mode, but unfortunately I have difficulties in receiving more than 1 character. It would be used for the device to wa...
Howdy,As the title suggests, I seem to be having some issues with FreeRTOS if I try to use a timer as the timebase source. The processor that I am using is STM32F745VET, but the MWE that I will try to describe should work on any system.The SMT32CubeM...
Hi, according to the Reference Manual and the Datasheet of the STM32L152 the I2C cores are supposed to support SMBus. However, there are no HAL drivers for SMBus for this MCU. If I configure the I2C cores as SMBus in CubeMX, CubeMX will generate Init...
I have the following couple of questionsQUESTION :1) what is the difference between USB drivers in the cubemx standard hal library middleware and CMSIS USB Middleware based on the following 2 cases?CASE:1) In STM32CUBEMX, When I use STM32 standard H...
I am using HAL_I2C_Master_Transmit and HAL_I2C_Master_Receive commands to read device ID of various sensors. I wrote a simple code to do that. It works for some sensors (e.g. MCP9800, HDC1080). But it doesn't work for some other sensors (e.g MLX9016...
hi I am handling two different interrupts:- tim3 interrupt- gpio external interruptnow I want gpio external interrupt to have a higher priority than tim3 and that can also interrupt tim3 ....How can set i? HAL_NVIC_SetPriority (EXTI15_10_IRQn, 0, 0);...
Hello,I am using STM32CubeMX to config STM32H743 for CDC class.When I analyze the data I get on the PC I notice the following1-Some small messages are Splitted into two packets2-when I send Several messages in series some messages are missed, but whe...
In **STM32Cube FW_L4 V1.13.0**,the HAL Library's SD driver has a typo in the register macro definitions for the SDMMC's power register.Specifically in the file `stm32;4s9xx.h`, lines *18127* -> *18141* the HAL library generates:``` C/****************...
void HAL_PCD_SuspendCallback(PCD_HandleTypeDef *hpcd) { /* Inform USB library that core enters in suspend Mode */ USBD_LL_Suspend((USBD_HandleTypeDef*)hpcd->pData); /*Enter in STOP mode */ /* USER CODE BEGIN 2 */ if (hpcd->Init.low_power_en...
