Posted on February 12, 2018 at 07:12I used STM32F469I-DISCO and STM32F429I-DISCO to testing Standby mode function by PWR example(Attach). Standby mode function is no problem on STM32F429I-DISCO. But in STM32F469I-DISCO , used RTC wake up form stand...
I am trying to receive some uart input from data that is an unknown size. I should end on \r\n or on an OK or ERROR received. The issue I am having with interrupts(HAL_Receive_IT()) is obviously losing too much data. I have also tried to implement t...
Older CubeIDE generated following SystemClock_Config.void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; RCC_PeriphCLKInitTypeDef PeriphClkInit = {0}; /** Initializes the R...
I have implemented my entire application in Touchgfx and FREERTOS and using the NOR flash as the external memory device. Now, is there any way to copy the entire code stored in NOR to SDRAM and run execute from there. Just like boot loading from NOR ...

I have a tilt sensor KX112 connected to the STM32L151CC on I2C2. It seems to work fine but at times the I2C bus comes up as busy and the sensor cannot be read. Rebooting the board solves the problem for a while but it crops up again. I am running th...
I have working external clock source HSE system clock configuration, now wanted to change to HSI (internal clock).But simply changing to HSI will not fix all the Multipliers and dividers to get same frequency output. Is there way to import the System...
HI,I am using the STM32F411E-DISCO board.and, I'm going to read the image from SDcard and deliver it to FT800 by SPI.The problems that have occurred are as follows.If I use SPI without SDIO, FT800 works normally.If I only use SDIO, I can read and w...
