Hello, I'm trying to understand how the HAL_SPI_TransmitReceive_DMA() function works when my mcu is in slave configuration.If I want to transmit and receive data multiple times do I have to call the HAL_SPI_TransmitReceive_DMA() after each transfer o...
Hi ! I am trying to port X-CUBE-EEPROM_V2.0.0 Emulated EEPROM application for STM32L476_Discovery application to STM32L412CBU device and following error appears in the flash_interface.c file flash_interface.c(151): error: #20: identifier "SYSCFG_MEMR...
Hi!Have a problem with SPI.SPI configured as SSI master RX only, and for the first transmission SPI generates additional clock cycle for one more word. What can be cause of such behavior? But it's work fine with less frequency (125 Khz)Here is initia...
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?
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...
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...
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...
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...
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...
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...
