HiI am using the STM32G070CB in a new product.I have the GPIOD0 and 1 connected to be digital inputs (they are to be connected to open-colector device), as such i have enabled the internal pull-ups in the GPIO configuration.The strange thing, is that...
I am running my code on an STM32L476RG which generates a UART interrupt every time it receives data. I am using UART2 for this purpose and USART1_IRQHandler is called after I send data from my terminal. But inside HAL_UART_IRQHandler, my code gets s...
Hi everybody,actually i'm working on a project involving a STM32F7 MCU and a modem Telit 4G/LTE connected via UART. I have to implement MQTT protocol, for which i choosed PAHO (highly used and suggested). Do you suggest working on bare metal or RTOS...
I use MCU STM32L073, set VDDA=VREF+=3.29V, VSSA=VREF-=GND=0V.I read Vrefint_cal for (0x1FF80078), get the value of Vrefint_cal = 0x680get Vrefint_data from ADC_CHANNEL_17, get this value is Vrefint_data =0xbb7 the code is here:///////////////////////...

Hi,I'm currently trying out the configuration of RTC in the STM32F407G-DISC1 using Atollic truestudio.I was successful in enabling RTC registers write access by setting the DBP bit in PWR_CR registers after system reset, but I'm unable to write the k...
Hi all,I develop rough environment IoT sensors that are completely potted in polymer epoxies. I use a STM32L432KC MCU inside to drive different sensors and RF radios. My sensors also integrate I2C RFID memories and magnetic switches in order to inter...
can anybody help how to program it because i have done it but i don't where I am wrong
