Can the ADC regular channel and injected channel of STM32G4 not be used at the same time? Is this a bug?
I use cubemx (6.0.0) to generate ADC1 configuration code, for example, ADC1 channels 1, 2, and 3 are injection channels, and TIM1 channel 4 is used to trigger, and ADC1’s 4, 5 are Regular channel. STM32F4 can work very well. But STM32G4 does not wor...
CAN is not initialised when RTC enabled
I am designing the application that uses both CAN interface and RTC. I noticed some weired behaviour that I need to fix somehow. Directly after upload the application starts and CAN working properly. With battery present (there is power on VBAT) if I...
Low Level I2C readByte out of sync
Hello,I am trying to implement a low level I2C readbyte function, currently trying to read out register 0x41 (TEMP_H) and 0x42 (TEMP_L) from an MPU9250. The issue is that when I debug print the values, it seems that TEMP_H_Buffer appears to have the ...
Resolved! DMA1_Channel7_IRQHandler doesn't get called
HiI am trying to do a simple USART communication via DMA (LL Drivers). I want to send two chars to my STM32F103 from my PC which are received by DMA. In the DMA RX transfer complete callback I want to send some text string, also via DMA back to the s...
use timer to decode pulse/step + direction signal?
STM32 timers can decode quadrature signals.STM32 timers can count external pulses.can STM32 timers do pulse counting AND take counting direction from a second external input?my current solution (on an STM32F303CB/CC, but also F103) is to let the time...
Problem with USART2 of stm32 f446ze
Hi, I am also new to stm32 micro controllers. I am trying to use UART2 of my microcontroller which is not default(It is not connected with the ST-Link, hence no virtual COM PORT), I am using a USB to TTL connector(TX,RX and GND) for this, I am taking...
Resolved! On the STM32H745 platform，When I use the memcpy or memset function to access external SDRAM（0xC0000000），If the address is not double byte aligned, the program enters harddefault.I tested the same situation on M4 platform without any problems.
memcpy(0xc0000000,buffer,2) this is okmemcpy(0xc0000001,buffer,2) this is error
UART interrupt not hitting without connecting debugger.
I have a Stm32f030k6 custom board and I'm using Keil uV5 IDE. The MCU is interfaced with wifi module over UART. But stm32 wasn't responding to the events sent by wifi module. After lot of testing I found that the UART interrupt is not occuring when s...
