Hi, I have an STM32L4x6 processor.I'm reading data using ADC and DMA, and after the HAL_ADC_ConvCpltCallback, I process the data with a Fast Fourier Transform. Originally, in bare-metal, I had a flag in the main loop, and when the interrupt occurred,...

Hi,I've created a PCB with an STM32L4x6 microcontroller and several peripherals, mainly I2C. I want to sample data at 512Hz using the internal ADC. The original plan was to configure the ADC with DMA and a timer, I'd put the MCU into other low-power...

Hi, I would like to adjust OCV parameter in STC3115. In datasheet I see equation for calculation OCVtab value. But I don`t understand it. If I have STC3115IQT and I can set 100% SOC from 4.313 V to 4.22V.(4.22-4.313)/0.55 = 0.05 but to register I ca...

Hi, I have STM32L496 and use Freertos 10.2. Everything is fine, but I would like read data from queue without removing from the queue. I discovered function xQueuePeek() but I dont know how to use it if I can read specific item from Queue. For examp...

Hi, I have custom HW on HW I`m using MCU STM32L496RTx and SD card. SD card is connected with SDIO to MCU and in FW I`m using HAL libraries - DMA+SDIO+FATFS.My aim is to periodically save datasets to SD card. I generate string with 51 characters. I ...

Issue solved.The problem was caused by the RTOS kernel Awareness - RTOS Proxy being enabled, to see the thread properties during debugging. However, when switching from RTOS Proxy to J-Link, the performance issues were resolved immediately. But, of c...

I have found the solution to this problem:2 way (RX,TX) dma doesnt work, I dont known why...But shared DMA channel yes but in BSP_driver_cd.c CubeMX doesnt generate propertly Write *** Read function. in file bsp_driver_sd.c in function modify BSP_SD_...

Tried set up only SDMMC. If set up SD 1bit or MMC 1 bit it is doesn't work. In state figure MMC_STATE_READYIf I set MMC 1bitI got error in:SDMMC_ERROR_CMD_RSP_TIMEOUT for CMD1 If I set SD 1bitI got error in:SDMMC_ERROR_CMD_RSP_TIMEOUT for CMD55 pleas...

Oh, thank you. I thought eMMC cards is widespread device. Where find example ? I checked L4 1.16 package Eval boards but not finded anything.Thank you
