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...
I'm trying to write three functions: to start an ADC conversion, wait for it to complete, and retrieve the results based on the low-level drivers from ST. The issue I'm facing is that I can read the first channel (LL_ADC_CHANNEL_0) with the correct v...
Hi All I am using STM32L053 board for a product development. I am using RS485 communication Protocol. I am sending Data from Computer to the processor to get the response. When I send the data, I get proper response. but out of 10 times say 1 time t...
Hey everyone! I'm trying to decrease the clock speed of TIM3 on my STM32L452RET6 (NUCLEO-L452RE) and i've run into issues. I think i figured it out already but I just don't understand why the problem is. My clock tree looks like this in CubeMX:With t...
