STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
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...
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...
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...
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...
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 */...
Hello.I have a problem with external eeprom.In my codes, I can read multiple datas in one time. I can't change. But I want to read/write it continous time.How can solve this 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...
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...
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...
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...
