Good day everyone,   I have a slight issue, I'm storing data in the form of uint16_t data types.This data will be read in from an ADC and have values of 0 and 1. I'll have an array of 192 of these 16 bit values that I'd effectively like to store in a SDcard. The problem is that I can't directly send these to the sdcard using fwrite as it would be… (Show more)

Is there a quick and clever way of inverting a PWM signal in software (I am using timer 2 of the Discovery Kit board/STM32L100)? Was looking for the complementary feature but I don't want a pair of PWMs, just the inverted of the original signal (top).   Thanks in advance!

Hi STM community, Currently we are developing an application with STM32F779I eval board.I am using Cube Mx and System work bench for STM32. We are facing issue with RAM.My application uses FreeRTOS, FatFS and SD Card driver and also CAN driver. Actually when we try to allocate memory using malloc() we are getting Hardfault error.This implies out… (Show more)

Hello,   I'm starting a project with an STM32F746VG, so I'm playing with the adequate Nucleo board.   I wanted to compare the speed based on different optimizations of the CPU, based on the exact same code, just with different optimizations on (everything is compiled on O0).   I did my experiment based on the cycle count for the… (Show more)

I am using usart1 for asynchronous communication. Microcontroller is nucleo STM32F103RB.   Here's is how I am receiving data if parity bit is not set, char USART1_Receive() {     if((USART1_SR & 0x00000020) == 0)    // no data available          return 0;     return USART1_DR; }   My question is, how should I receive data if… (Show more)

Hi, I am using the STEVAL-IHM041V1 demo board to develop my own application. The mcu is STM8S103F3P6. I checked the EEPROM locations to verify that the EEPROM read/write are fine when the +5V is stable. But I have problem trying to save the last data settings to EEPROM after the power has been removed. The EEPROM write is happening before the… (Show more)

Hello everyone. My current project requires working with NFC and RFID interfaces. I use ST M24SR to interact with NFC-powered smartphones, NXP PN532 to read 13.56 MHz cards and inhouse-designed circuitry for reading 125 kHz em-marine cards. So I have three antennas put one inside another. I turn each of these ICs for short moment of time to scan… (Show more)
