STM32F446 RTCI seem to have a problem with this part of the MCU.I am using the HAL to retrieve date and time.Yesterday evening I set the time (about 22h something).Time was displayed correctly.Today in the morning I have a time of 33h27 retreived by ...
Hello, guys!I have problem saving data in STM32L0's flash memory.If I save the data twice in the same location it works fine.If I save the data once CRC check fails - data writing goes wrong?!I have attached my code.Sorry for the "magic" numbers in t...
Hi Everybody,I have a difficult problem. I use STM32F469I-Disco to porting new LCD on it.My LCD driver IC are ILI9806E and ST7701s. they are having the same problem.they can be lighted on, but image is not the same as my setting.Example: I use BSP_LC...
I have a nucleo F746 board powered from CN1 (USB from the ST-LINK side) and I am interested to use the other USB port (CN13) configured as Virtual Serial Port (VSP) and start debugging with the printf () and log on a PC (the STM32 does not yet have ...
I have inherited a PCBA that needs to generate a fixed number of PWM pulses on TIM2 CH4.I have successfully setup TIM1 as the Master (with repetition count = 0) and TIM4 as a Gated Slave.TIM1 CH1 is generating 2kHz PWM indefinitely.TIM2 CH4 is genera...
I'm sure everyone else has noticed how the two pins to VCAP seem to be placed just over a complete side of the package away so there is bound to be some resistance/inductance in the tracking. I was wondering if anybody has ever hit problems with thi...
My current code configures the RTC and updates date/time on initial turn on only.void set_date(void) { /* Select LSE as RTC Input */ __HAL_RCC_RTC_CONFIG(RCC_RTCCLKSOURCE_LSE); /* Enable RTC */ __HAL_RCC_RTC_ENABLE(); RCC_OscInitTypeD...
DocID024030 Rev 9 states:4. If VREF+ pin is present, it must respect the following condition: VDDA-VREF+ < 1.2 V.Normally, I would just make changes to satisfy, but a change at present product development stage is very costly. Using LQFP144 pkg if ...
Hi, I am using stm32f103vc(100pin-LQFP) controller in my board while i try to program my board using st link v2 programmer it shows error message like "dev target held under reset".Programming pin connected as follows.SWCLK--->PA14SWDIO--->PA13GND...
Hi there,i want to implement my MCU to program a FPGA via SPI. Is there any helpful guidelines on this topic? I am a newbie with STM and i hope that someone can help me here.Thanks in advance.
