Hi I am a hardware design base person, it's been a while I wrote the code. I have one STM NUCLEO-F401RE board and one sht3x i2c sensor. I wonder how to make them working (at least print sensor information via UART serial port). I see some source co...
Hi all, im using STM37H74x evaluation board and i managed to get most of it working (PWM, DAC etc..)but when i try using the ADC i get strange input, putting the configuration aside, this is what my main looks like below.im using ADC1 ch6, according ...
Hi guys, I want to wake up my MCU every 10 sec. And I had to write some code as follows: if(__HAL_PWR_GET_FLAG(PWR_FLAG_SB) != RESET) { __HAL_PWR_CLEAR_FLAG(PWR_FLAG_SB); sprintf((char*)uartBuf, "wakeup from standby\n"); HAL...
I am able to transmit data from STM32WL to Arduino UNO board using USART Serial communication but on following the same procedure I am not able to transmit the data from STM32L152RE to Arduino board though baud rate matches and the code and circuit c...
Hello STM32 Community,I hope this message finds you well. I am currently working on a project involving the STM32H747XIH6 microcontroller and facing challenges in creating a standalone bootloader using USB OTG FS.Here are the details of my setup and ...
Hi,I am working with STM32G4. I am generating 1Khz PWM from my Timer2 and TImer1 I am using for delay(I configured it for 50 usec delay with interrupt).Both timer2 and timer1 working as expected.1.For every pwm pulse start I need to read adc for 50 u...
Hello, I have tried for the last couple of days to get use 2 pots to change the frequency and duty cycle of a PWM signal using "Bare Metal" programming due to the flash limitation of the STM32L011K4T6 I rapidly ran out of space using HAL and was not...
I was wondering, how a repeated erase over pages, that have been previously erased, but not written, would affect the lifetime of the FLASH.
Hi everyone,I am using STM32F410 CPU.I need to send 4096 bytes of data via SPI using DMA transfer.The transfer should be triggered by each TIM1 event.I have read these two posts:https://community.st.com/t5/stm32cubemx-mcus/trigger-spi-dma-transfer-fr...
In datasheet for STM32G431 series and RM0440 (applicable reference), there are references to ADC12 (I'm encountering this when working on ADC converter, pin and channel assignments for an application.) There doesn't appear to be a specific definition...
