Hello, I'm using a STM32L071CB. Some times my code go to HardFault_Handler. After many test I seen that the interrupt start from     if (ADC_IS_CONVERSION_ONGOING_REGULAR(hadc) == RESET)   in HAL_StatusTypeDef HAL_ADC_Start_DMA(ADC_HandleTypeDef* hadc, uint32_t* pData, uint32_t Length)   I don't understand why this error. Code generate with… (Show more)

An ST-Link (from Nucleo-64) don't want to read an STM32F030RCT6 under Windows 10 (64 bit) with a message "Can not connect to the target". The most interesting thing is it reads an another same board already programmed. But this doesn't mean the clear board is broken: it could be read with the same programmer but another computer with Windows 7 (32… (Show more)

Can not find any related flag in RM0090 at lest.  Strongly need to receive frames with lengths down to  12 byte totally (having only SA DA at most )

I have a problem with STM32F415RG....   My project has two system of wakeup from standby, first is PA0 pin and other RTC Alarm.   If i put a single way of wakeup, like only PA0 wakeup work, if i put only RTC ALARM wakeup work, when i put both, not work...   I make many test:   When i put a alarm 30 seconds after standby, and i move the PA0 pin… (Show more)

Hi,   i'm working with STM32F415RG and i want only ask a easy question.   I'ts possible to detect if the chip (during StandBy mode) is wakeup from RTC ALARM or from PA0-WKUP pin ? some flag will be setted ?   Regard

I'm currently developing an app based on STM32F429I-DISC1 board. It works great when the board is connected to STLINK through miniUSB cable, program runs and data are displayed on LCD display. One of the requirements is to make the board work from external power source. I'm using 5V pins to supply power. In this case the program does not start ,… (Show more)

Hi,   After generation of code with STM32CubeMx (release 4.21.0), Error_Handler() interface present in main.h is not specified to be used in C-style linkage as it's done in the rest of the code.   This performing a linkage error with IAR C++ compiler.   Please, fix it in the next release.   Thx and Regards

I know in some RAM components, there is many blocks in it and the more the memory usage is required, the more blocks it open for the algorithm. So that the power consumption is also increased.   So for ARM-Cortex M chip, for example STM32F series, how much power consumption the RAM component has taken in the whole system, is there an existing… (Show more)

Hello all,   I'm using the STM32F429 Discovery Kit and running the LTDC in 8 BPP (L8) mode. I have STemWin and am displaying their colour bar sample. I have a problem with colour conversion where the colour bars appear correct in the WIn32 simulator but are incorrect on the discovery kit.   For the simulator I have in LCDConf.c: #define… (Show more)
