Posted on March 21, 2018 at 10:40HiI got generated code from STM32CubeMX for STM32F373CCT where it is configured the clock with HSI and PLL. When debugging my CPU hangs after I enable PLL.Currently the only way to run firmware is using HSI without P...
Posted on May 15, 2018 at 16:08Hi Everyone! I'm developing a BSP file -board support package, for a personal purpose card ' ad hoc ', using the STM32H753XI. While creating the PDSC file -pack description software component, I needed to include ...
Posted on May 15, 2018 at 15:32Hi, i'm having an issue using Stop mode on my nucelo board.At the moment i program my StopMode to do this : - Wakeup on RTC counter- Do not remove / change the states on the GPIO (I need this functionnality on my proje...
Posted on May 15, 2018 at 13:48Please see code below.I'm trying to read from USART using DMA. Please see the last line DMA1_Channel3->CCR |= DMA_CCR_EN;When I step over that line, CNDTR instantaneously resets to zero like it has finished reading, a...
Posted on May 15, 2018 at 08:58hi I am new to ARM, and I am just started with STM32F103C8T6 blue pill Board, I am compiling with keil uvision 5 with ST-Link v2 programmer. First, I checked with blink program on pin PC_13, the works good. But then I ...
Posted on May 14, 2018 at 10:05Hello all I am quite new to STLink. I am trying to program a microcontroller using STLink/V2. In normal situations it works perfectly. but at times i do have a communication error with STLink and it shows' USB communic...
Posted on May 07, 2018 at 13:31Hello all,I want to use the IAP possibility off my Nucleo-STM32L073RZ. I read the AN4657 and downloaded the X-CUBE-IAP-USART folder. I thinck I have an generell problem of understanding the iap. I have a little program...
Posted on May 11, 2018 at 03:48I use ST-LINK utility V4.2 to program a code to external flash, always fail.Attachment is my code. it include embedded code(start at 0x08000000) & external flash code (start at 0x90000000).Platform : STM32L496G-DISCOEx...
Posted on May 07, 2018 at 13:03I have a STM32L051 microcontroller and use the STM32L0Cube HAL.I read fom the manual, that the STM32L0 have a possibility to provide a stable reference voltage for external ADC/DAC/... This is the VREF(BUF). If I under...
Posted on May 02, 2018 at 21:24Hi everyone,I have a problem regarding the i2c communication with the 1.9 release of HAL for stm32f0.I use the i2c2 peripheral of stm32f091rc microcontroller to communicate with a EEPROM.This peripheral works very well...
