Hey folks, I am writing to seek guidance as a newcomer to the MCU (Microcontroller Unit) realm. My objective is to facilitate audio recording utilizing the STM32H747 microcontroller. I kindly request assistance in steering me towards the appropriate ...
Hi all,I need help. I am using the STM32-F446RE Nucleo-board and I have it connected to a 1602A LCD display. I am trying to write "Embedded" on the first row and "Systems" on the second row, but I get it all in row 1. Can someone look over my code an...
Newbie here.I discovered the STM32 Nucleo development boards and there seem to be lots of models.After clicking and clicking I can't seem to find the one for the STM32H747XI - TFBGA240+25 Package...Or at least one with the same number of pinouts... e...
if i use static UART_HandleTypeDef huart8; in main.c . when i want to run it in fpvisionai.c HAL_UART_Transmit(&huart8,etc) say huart8 undeclared , should i use include <main.h> in this file,o how to set UART_HandleTypeDef huart8 as global variable
if one pin have two pin name for example d14 could be mcu pin as PD12 ,o PA9 at gpio port. But for gpio_init()should be PD12, the PA9 is for which part to use?
I'm use uart8 to send data to arduino, but arduino no receive nothing, all the program is right complier,and the D1/D0 should be right(only have uart8).https://community.st.com/t5/stm32-mcu-products/stm32h747i-disco-virtual-com-via-usart-to-arduino/m...
My project (Stm32H753) has 2 identical external ADCs, one on SPI2 and one on SPI3. The one on SPI3 is working fine, but I am having problems with SPI2. The code for them are the same, except of course different 'hspi' and pin assignments.The SPI is c...
Hi,I have a problem with an 24LC64 EEPROM, it is not a bad chip because i have tried 2 on diffrent boards. I am using the STM32G0B0 This are my I2C settings:I am using this libary : https://github.com/nimaltd/ee24/blob/master/ee24.cI only get 255 ba...
If i use the serial interface USART1 HAL_UART_Transmit()( is directly available as a Virtual COM port of a PC connected to STLINK-V3E USB connector CN2) could show in com9 in pc, but uart8(D0/D1) in com9 didn't show anything, This result should be ri...
Hi all,I trigger the ADC through TIM 2(1HZ/s) and set the ADC to Dual Mode. ADC1 & 2 each have 5 channels. multimode.Mode = ADC_DUALMODE_REGSIMULT; multimode.DualModeData = ADC_DUALMODEDATAFORMAT_32_10_BITS; multimode.TwoSamplingDelay = ADC_TWOS...
