The STM32H742xI/G STM32H743xI/G data sheet (DS12110 Rev 7) implies VDDLDO can be supplied separately from VDD. “When it is not available on a package, the VDDLDO pin is internally tied to VDD.�? And “VDDLDO ≤ VDD�?. However, on the STM32H743VIH6, VDD...
Hi!I have a Nucleo F401RE that works great! But the problem I have is that the board cannot be call the function HAL_UART_RxCpltCallback after it has recieve its bytes.I have:Using DMAEnable global interuptUsing USART2Calling DMA inside HAL_UART_RxCp...
Hi there!I hope someone can help me. Afther a couple of years i start again to program the STM32 microcontroller (STM32F051). I need the use a UART for trasmit and receive data. For the trasmission no problem work weel ( i use the interrup HAL functi...
Hi,I am trying to understand DMAMUX possibilities and usage.My target is to implement auto refresh of external muxed (scanning) SPI LED display. Just 3 shift registers in daisy chain. 1 byte selects current characters (mux) and 2 bytes are contents o...
@The things i use:Hardware: Stm32F446RESoftware: CubeMX V.5.4 ; Matlab R2019b ; CubeIDE V.1.1 ; Mat-Target My Question is: Where is the Mistake in my Programm. I defined the PA5 as a Gpio output because that´s the Output for the LD2 LED on my board w...
I would like to send data with modulation "B-PSK coded with Peak Noise Avoidance". Most of the time I receive instead of DL_DataConfirm a response DL_DataError with error cause 0x08. Unfortunately, that error code is not documented in user manual. Co...
The STM32F469IG needs to be interfaced with the ISSI IS16100H-7TL (512K x 16 bits x 2 Banks, 16Mbit SDRAM). This SDRAM has 12 address inputs, A0 - A11.Should the SDRAM controller in the MCU being configured for 12 bit address and connect FMC_A0-A11of...
In my STM32H7 application I start a timer, stop it in an update interrupt handler (by setting ARR to 0), then when appropriate I set a new ARR value thus restarting the timer. This happens very frequently. During each such period I execute a number o...
Hi,I am using STM32H753 controller in my design, I am measuring the current consumption in vbat mode with the battery and found it to be around 1uA. The RTC Configuration was RTC_Alarm_A enabled.But disable the Alarm_A in the RTC configuration, the c...
RM0440 table 7, even in rev. 2, does not describe the flash layout of devices with less than 512 kB flash in dual bank mode.Is there a gap between the two banks is this case or not? The textual description doesn't even mention devices with less than ...
