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....
Hello all.I am new working with the SMT32 microcontrollers and I need your help.The project deals with 3 communication channels USART to 19200bds (usart1, usart2 and usart3)The microcontroller used is the STM32F103ZET6 and would be connected to 3 dif...
Posted on February 26, 2018 at 18:10 Hi, I was doing my thing, writting and debugging code with System Workbench and after a while ST-Link refused to work anymore, out of the blue. I had not changed SWD pins nor related settings. It just stopped ...
Thanks for the nice possibility for "PWM input mode" measurement / frequency measurement - works very perfect on TI1 or TI2.But the register descriptions for SMCR and CCER are somehow contradictory in RM (e. g. 37.4.3 and 37.4.9 ... but concerns also...
hi i'm reviewing rm0008 ref manual for stm32f103 the adc.accordingly, adc clock max is 14mhz and it takes 14 adc clock cycles for 1 conversion - hence 1msps per ADC.however, from the RCC section the available prescalers are 2, 4, 6, 8and if we take 7...
