When I power my nucleo through the 5V pin, with a 5V supply, the behavior of the controller is not normal. If I power it by USB, it works well. I read the User Manual, have I misunderstood something? What could be happening?
Hello, I was trieng to use STM32Mat (with simulink) and came across some errors.I discovered that the HAL Library was updated but the STM32Mat wasn't.I'm willing to code everything by hand without using Simulink but I would need documentation on the ...
I registered at AWS and got 5 certs, which is the dev kit sw asking for? what is the thing certificate that i am asked for?
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 */...
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...
