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 ...
When UART works in RS485+DMA mode, after initial, HAL_UART_Receive_DMA/IT enalbe manually, I fould systick woundn't work any more.Who meets this issues or has any advice, comment is welcomed, thanks in advance.UART configuration in MXCube
Hi everyone, i'm using uP STM32F103C8T6 processor and GPS module NEO M6Q with standard uart configuration on 9600 baud-rate .I enable global UART2 interrupt to receive data from GPS module on every second. But for some reasons, interrupt starts skip...
