Ask questions, find answers, and share insights on STM32 products and their technical features.
As capacitive sensing undergoing such a rapid growth and penetrating more and more industries, it attracts the interest of many engineers with little to none experience with it.That’s why, we have created this guide and we would like to share it wit...
Posted on May 18, 2016 at 17:18Hello, I'm using an STM32F373C-EVAL and both the Atollic and AC6 IDE tool. When I try to import a project from the STM32CubeF3 V1.4.0 into both the IDE, I get a hardfault error during the __libc_init_array branch instr...
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...
