The evaluation board STM32F429I-DISCO has a Synchronous Dynamic RAM: ISSI IS42S16400J I must use this external RAM instead of the internal RAM so I had a look to the example from "FMC/FMC_SDRAM_DataMemory"The example looks quiete easy. Nevertheless I...
Hi,I'm using STM32L072 Discovery Board and generated UART code using CubeMx, I'm able to transmit the data via UART but not able to receive the data. Please help me in this regard.int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ ...
Hello everyone, I'm using RTC on board NUCLEO-L053R8, so I have some problems. How do I connect a battery in this board? I know that if I want save my battery lifetime I have to put my microcontroler in a mode as StopMode, but how can I do that when ...
hi i'm using HRTIM for PWM output.i could complete pwm output. but i want to stop it at pulse count that I want.is there any good way to stop output at i set pulse counts??

This code is from STM32H7xx_hal_dma.hwhat is __DMA_HandleTypeDef describing ?is it weak ? for what purpose ?typedef struct __DMA_HandleTypeDef { void *Instance; /*!< Register base address ...
STM32F446 in my case...When the ADC finishes a conversion and the DMA controller deposits the converter data into memory, what is the overhead ? i.e. How long does it take ? Is this shown in the documentation anywhere ?I would assume that as soon as ...
Hi,We are developing a board with the stm32l432kc comunicating thru CAN bus @500kbit/s, and after reading about the internal clock precision (1% at best for HSI16 in the 0-85C temperature range) we are concerned that it could lead to CAN communicatio...
Hi,We are using PF3 for one of our output function and we need to pull that pin down internally. So we are configuring that pin as output enabling clock etc and using LL driver "LL_GPIO_SetPinPull" function with port and pin with argument "LL_GPIO_PU...
I am using Thermistor (NTC Type ) as temperature sensor .So to calculate the temperature from adc value of STM32 I am using this formula(taken from this site :- https://www.jameco.com/jameco/workshop/techtip/temperature-measurement-ntc-thermistors....
