STM32G474 ADC offset
There is only 4 offset registers OFR1...OFR4, does it mean I can set offset for 4 channels only? Or they are dedicated to injected channels?

Tx to Rx UART DMA loopback
Hello,The Tx and Rx pins of UART 4 in my code are shorted. I want to send an incrementing array from the Tx pin and receive it back from the Rx pin.For this I wrote a for loop that increments every element of the array. The for loop is run from the c...
Resolved! Sending data via I2C doesnt work properly
Hi,I want to controll a ST7032 Display Modul via I2C with a STM32G071G8 MCU. Unfortunately I can't manage to send data bytes to the Display. For sending data I use the HAL function HAL_I2C_Master_Transmit() as followed: (for testing)HAL_I2C_Master_Tr...
STLINKV3 VCP1 & VCP2 BREAK & RTS command
Dear All,I try to use the 2 VCP on the STLinkV3 and I have some problem with standard command...I cannot Send a BREAK command on the TX line I cannot send RST ON/OFF command on the RST line of the VCP2When I use this command nothing append... Any ide...
Resolved! How to trigger ADC conversion via timer correctly?
Dear Community,for some time I've tried to set up the hardware of a STM32F429ZI to periodically trigger a discontinuous ADC conversion with 2 channels.I'm using TIM1 in PWM mode to generate CC interrupts with TIM CH3. The timer is running in center m...
what affects the delay time between message caught and respond of HAL_UART_Receive/Transmit_IT ??
I'm writing a throw-catch case of 2 chips, the Host throws an message onto UART1 bus, then the Slave catches and shows message on UART2 for debugging, there are a delay between catch and throw, but the delay time is not always the same, in my opinion...
STM32H745 TIMER peripheral to memory DMA
Hi,I'm trying to get a timer with external clock (ETR2) to trigger a DMA transfer from GPIO to memory on a STM32H745 with no luck.I'm using cubeMX to generate the code below.The timer seems working. TIM2_IRQHandler is triggered periodically.However n...
STM32L451RE - How to detect a wakeup event in shutdown mode?
STM32L451RE - How to detect a Wakeup event in shutdown mode?Hi,I connected a Accelerometer interrupt on Wakeup Pin 2. In Standby mode "HAL_PWR_EnterSTANDBYMode();" I can wakeup MCU by moving Accelerometer.After that, the flags "PWR_FLAG_WUF2" and "PW...
Resolved! ADC + DMA - multiple channels filled into buffer in wrong order?
Hi,I am setting up my STM32F405RG with 3 analog inputs on ADC with DMA.The problem I'm having is that the ADC buffer is being filled in the wrong order:For example, I have channel 11, 12 and 13, with ranks 1, 2 and 3 respectively, so I presume the AD...
LPTIM pulse counter
Hi,I am using stm32L431, in the documentation says that when using LPTIM pulse counter the 5 first pulses is lost, after this the counter works fine. But in my project this situation is not acceptable, because in some cases I use less than 5 pulses.I...
