Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Hi, I have created a code snippet to communicate with I2C using LL API instead of HAL. The code is given below uint8_t temp[2]={0xF9,0x00}; while(LL_I2C_IsActiveFlag_BUSY(I2C1)); // Wait until the I2C bus is not busy LL_I2C_HandleTransfer(I2C1,...
Hi!Some time ago I did a post asking for a problem i had with this board used as a USB HID Device for a Midi Keyboard project when i wanted to read the value of a potentiometer with the ADC using DMA and send it as a Control Change command.I solved t...
I've connected the Nucleo-H755ZI board to a GPS module (GY-GPS6MV2) via USART2 with a baud rate of 9600. The RX and TX pins are configured to PD5 and PD6, and I've enabled global interrupts to manage the incoming data. However, instead of receiving t...
I am not receiving the correct data from the NEO-6M GPS module when interfacing it with the Nucleo-H7 series board. Instead, I am getting a value of -1.888836e-019, which leads me to suspect that the connection with the GPS module is not properly es...
Hi,I am using the STM32H563 and WF18GTLAADNN0 display with SPI for interfacing and the ST7735 library from Controllerstech. However, the application is not functioning. Could you confirm if any driver initialization steps have been omitted? Hardware ...
Hello,I am trying to convert HDMI ARC audio to I2S using STM32H7 series.AFAIK, ARC uses IEC 60958 SPDIF standard, which STM32 SPDIF-RX accepts.Is this implementation possible?Connection would be likeHDMI ARC(HEAC+) -> Inverter -> STM32H7
Hi there,I'm developing my own bootloader for a stm32H755 MCU and I would like to b able to write just a single 32 bit word (or even also a single 64 bit double word) to the flash.Using standards HAL API and theHAL_FLASH_Program function, I'm able to...
I want to control GPIO output using DMA and Timer. The target is generating a CLK signal of 1MHz and control PB0 synchronized with the CLK.I am using Nucleo-F411RE as the development board. I have followed the instructions from the forum and configur...
I am working with the STM32F429 discovery board trying to prove out the ability to do OTA updates via a connected cell modem, but I am having trouble getting the MCU to boot from bank 2. I have created 2 simple freeRTOS applications which blink the o...
Hi!I am performing a calculation in an interrupt as this:L1L2_filteredTimeNegFlank = ((TIM_GetCounter(TIM16)*50) + 206*L1L2_filteredTimeNegFlank)>>8;But it seems like that it sporadically computes the wrong value and it disappears when I reformulate ...
