Hello,For communicating with a sensor I need to send 32 bits as a clock for my sensor. As you can see in the 8-bit data transmission an interruption occurs during sending 4 bytes which is unpleasant for my communication. I wrote a Software SPI (bit-b...
Hello, I am uing STM32F103 MCU and I am having a small problem with the ADC. There is a 250 mV difference between the real voltage value on a pin and the value ADC gives me. When I measure the voltage on a pin it is 900 mV. But when I print out the A...
Hi all,I'm developing a low power sensor node using the Nucleo STM32L432KC development board, and I was wondering what the lowest power mode is from which the device can wake up and just continue operation from the next line of code after the sleep c...
Hello everybody,Regarding STM32 H7 family:I am going to use SDMMC module of one chip of H7 family,by my own C code and without using any operating system(if possible) .As I ponder the manual reference of the chip,I noticed to "sdmmc_ker_ck" or "SDMMC...
Hi, I'm using STM32F103C8T6.When i used encoder mode on TIM3 and 4, I found that it's really unstable, when I restart or reset the microcontroller, it often can not read the encoder data (about 3/5 times). I measured the voltage on these timers's pin...
HiI am getting too much noise in my signal as soon as I acquire it. The oscilloscope screenshot shown below is the actual signal. Below is the signal shown after acquisition through ADC. I have found no instruction for ADC calibration. What else can ...
Hello , I Am Working With Two STM32F030K6T6 Board ,Which is Used As a Boot-loader application With I2C protocol. So I Can Communicate Small Data But Some How I Can Not Communicate A Long Data To Transmitted or Received From Master To Slave Or Slave T...
Hi,I'm tring to set low power mode in an STM32L031 MCU, using a NUCLEO 32 for evaluation first.Now my aim is to set MCU in a low power mode, only checking some digital pins during this state.Anyway, I switched off analogs and LPUART beforw invoking ...
