The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hello, I would like some clarification on the internal flash memory wear of a stm32f722ret, which is rated at a minimal 10000 P/E cycles. An example:Suppose there is a flash block/page/sector with two bytes, A and B. Byte A gets programmed (for examp...
recently I used the STM32F072 USRT3 to communicate with my peripheral， the configuration of USART3 is follow：static void USART3_Init( void ){ GPIO_InitTypeDef GPIO_InitStructure; USART_InitTypeDef USART_InitStructure; NVIC_InitTypeDef NVIC_InitStruct...
Posted on June 28, 2018 at 22:18Hello everyonei have a question, i am using 3 Ranks ADC injected mode for reading potential resistors..the problem is when ever i change one value it affects the other channel reading.examplechannel 1 reading is 1.3vc...
i'm trying to sample 40 adc values by using dma which means i have configure adc with dma(interrupt).Time period is also a constrain which means that a value is read after every 500us.After obtaining 40 readings ,i disabled both timer and dma then se...
Posted on February 12, 2018 at 08:18CDC has 3 endpoints (IN, OUT and Interrupt). I have no problem with sending messages via IN and OUT (bulks), but there is a problem when I try use interrupt endpoint (0x82). I created similar method to USBD_CDC_T...
Posted on August 04, 2016 at 17:11Timer3 runs 2x faster than expectedI know what many readers are thinking but read onI set my STM32F746 (DISCOVERY PCB) for SysClk=216 MHzAHB Prescaler set to �1 thus HCLK = 216 MHzAPB1 prescaler set to �4 thus PCLK1...
recently I bought some new version (disc1) these start working by connecting USB,but they don't start by 5v external supply without USB connection to PC,I have to connect USB connection to PC and external 5v to proper pin then it starts working , now...
Hi.I downloaded some IWDG example code from Keil because I will use the IWDG-feature of my STM32F107. Configurations/init are located in this procedure://__inline static void stm32_IwdgSetup (void) { static void stm32_IwdgSetup (void) { RCC->...
I'm feeling really stupid about this. We were unable to debug in our circuit, so to check, we have a standalone STM32L021D4Px, mounted to a solderless breadboard. 3.3V is connected to Pin 14, ground to pins 9 and 1, NRST to pin 4, SWDIO to pin 13 and...
