Problem with scanf in STM32F4, it is scanning only the first char even I am requesting to scan an int or float. Details in description
here is the code I am using to scanint ScanConfig(__const char * format, va_list args) { unsigned i=0; char ch = 0; char buffer[256]; int ret = 0; while((i<sizeof(buffer))&&(ch!='\n')&&(ch!='\r')){ HAL_StatusTypeDef status...

Dear ST folks,I'm trying to configure the HSE clock output over PA8 on stm32F103 from scratch.Here is my code.#include <stdint.h>#include "stm32f10x.h" // Device header int main (void){ RCC_TypeDef *pRCC; GPIO_TypeDef *pGPIOA; pGP...
(HART) Highway Addressable Remote Transducer Protocol Stack or Libraries
Anyone has implemented their own HART stack? I need a very simple HART implementation, burst mode, just keep on sending out Universal Command 3. No need for HART input. Anyone can help me with this?
The ADC1 & ADC2 is configured in multimode with DMA and trigged by TIM1, but I only get half sample rate 20 kHz. What I have done wrong? Q2 I can only use TIM1 Trigger 2 Out Event to trig the ADCs. Why can I not use any other timers or events?

ADC read with STM32L433
would like to read ADC value for vbat consecutively.First read VbatSecond read VREFINT.implementation is like below. hadc1.Instance = ADC1; hadc1.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV4; hadc1.Init.Resolution = ADC_RESOLUTION_12B; hadc1.Init.Data...
STM spi master sending extra clock signals.
I am trying to communicate with an adc chip acting as a spi slave to my stm32f3 spi master. So far I am unable to make it work.After attaching an oscillscope I found out that if i send only 8 bits of data to the slave , I get exactly 16 clock pulses ...
Incorrect Get Time from RTC (year 2035 for example)
Hello everyone, I have an application that synchronizes the RTC with the current time using a 3G module. Once it is synchronized, the system gets the date and time every 5 minutes in order to store sensor samples with a real timestamp. Everything is ...
