I've got an STM32H7RS, and am attempting to use HPDMA to do a memory-to-memory transfer where one side is the FMC.The transfer works perfectly if I use GPDMA.With the exact same code (just replacing the GPDMA handle with an HPDMA one) does not work (...
Problem:I'm working with an STM32H743 and trying to generate a PWM signal (Center Aligned) on PE9 using Timer1 (TIM1). Although the PWM output is functioning, the frequency is not what I expect. I’m trying to generate a 1 kHz signal, but instead, I’m...
I have a STMCubeMX project in which I've changed to 1ms tick in ThreadX. This shows the following from printf:UX_PERIODIC_RATE=100TX_TIMER_TICKS_PER_SECOND=1000The attached STM32CubeMX project is ported from Ux_Device_CDC_ACM to run on the STM32H743I...
Good morning,I am trying to use the RTC and I managed to make it work as expected for the 24hs format, it has no delays and when resetting I could see how to make it save the time but I am having a problem with the 12hs AM/PM mode, the set to go fro...
Hi, I’m having trouble reading measurements from the ADXL345 using SPI. I’ve attached a picture from the debugger that shows a view of the variables. The SPI is configured as master full duplex, and I’ve included a screenshot showing the SPI configu...
Hi,I am implementing DFU over I2C to an STM32L476, trying to follow AN4221 and AN2606.For now I am focused on just getting some DFU command to work successfully over I2C, and I started with "Get Version" to get the bootloader version. I am able to ge...
Hello,I'm using the STM32F767ZITx MCU and the lwIP library to transmit and receive UDP packets every 1 ms.Everything works fine but sometimes, after the ARP table has expired, UDP packets are no longer transmitted for several seconds even though my S...
Dear MCD Application Team,in Drivers/STM32G4xx_HAL_Driver/Src/stm32g4xx_hal_uart.c you can find this check:/* Ensure that Frequency clock is in the range [3 * baudrate, 4096 * baudrate] */ if ((lpuart_ker_ck_pres < (3U * huart->Init.BaudRate)) || (lp...
Hi,My uC (STM32F30K6T6) is full in RAM memory.To optimize the RAM size, I have planned to reduce the Heap Size Memory (initial Heap size is 0x400).I do not use any manual memory allocation so, I think I will set it to a quarter of it (0x100), just in...
Gradually debug the DMA send function, HAL-UART Transmit DMA, and find that the function will judge a status bit of the serial port handle, gState. It will only send normally when huart ->gState==HAL UART State READY,And the reason why the first tran...
