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...
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...
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 ...
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...
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...
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...
memcpy(0xc0000000,buffer,2) this is okmemcpy(0xc0000001,buffer,2) this is error
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...
Hi Team I wanted to measure the power consumed by the device i.e. STM32H7B3I-DK while running any application like taskIs there any api that helps me to measure this can anyone help on finding a way to do this
I want to build a system based on the STM32H735ZGT6. The data sheet (page 115) refers to application note AN5419 "Getting started with STM32H723/733, STM32H725/735 and STM32H730 Value Line hardware development". However, I cannot find it.
