STM32f303k8t6 Nucleo board with DS18S20 Temp sensor.
Dear all, I want to read the temperature by DS18S30. For that I have downloaded the library for DS18B20 (not DS18S20, because not available) from https://github.com/nimaltd/ds18b20. I have added this to my project in Keil as shown in figure. But it c...
Does STM32H7 support ISO CAN FD?
The Reference manual states that the FDCAN supports CAN FD according to specification 1.0, but also states it is ISO 11898-1:2015 conformant.Also: There is a bit in one of the control registers that suggests the FDCAN can support both versions. Is th...
STM32F411RE using External power supply
Hello,to finish my project i want to remove my the cable wich is plugged in to my PC. So i need an external power supply. In the Datasheet i found the topic "external power supply" but i still dont know how to connect it. It says that i have to use E...
How to interface STM32F429IGT with an external SDRAM?
Hi,I’m trying to connect an external SDRAM (part no. K4S561632N) to STM32F429IGT. For that, I am using STM32CubeMX to generate the code. Shown below is the initialization and configuration of the external SDRAM:The IDE that I am using currently is Ke...
[STM32F091VCH] HAL_RTCEx_SetWakeUpTimer_IT does not work, help me.
I want to enter the CPU in stop mode and wakeup the CPU using RTC wakeup.I wrote the following code.----(void)HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 2-1, RTC_CR_WUCKSEL_2);HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON,PWR_STOPENTRY_WFI);/* STOP MODE */...
STM32F091 ADC DMA problem
Problem with ADC reading at 100 kHz via DMA.MCU runs @ 48 MHz, ADC @ 14 MHz. Configured via CubeMX.Trying to read one ADC channel (1.5 cycles), triggered by Timer 15 (100 kHz) using HAL.Cannot reach 100 kHz (see pictures). Blue are DMA interrupts (h...
Not detecting the usb device in Dfuse
I am trying port sample code via usb fs of STM32H743 MCU. I have installed dfuse in win7. But my device is not getting detected. In deVice manager I see warning mark on STM device in DFU mode. If i check the details, it says digital certificate is no...
Why is the driver code for different lines (F2, F4, F7, etc) duplicated by ST
If you compare the code from e.g. the STM32CubeF2 and STM32CubeF4 archives you'll see that its almost identical. The only differences seem to be the name of the files and defines (have F2 or F4 in them) and the F4 code containing some additional fun...
STM32F746G Sampling Error
I use the BSP functions to record audio. The sampling frequency is set to 8000 Hz and the buffer size to save the recorded data into is set at 8000 elements long. It would make sense if the time to fill up the buffer is 1s. However it takes exactly 5...
