Hi,I am measuring a STM32L4A6VGT board power consumption. From the datasheet, in standby mode should be 120nA while I got the value @ 19 mA (last Friday). The FW does nothing, in main after MX_XXX init, call HAL_PWR_EnterSTANDBYMode(). Now I am gett...
Posted on September 21, 2017 at 09:26Hello!I use the microcontroller STM32F205ret6, STMCubeMX v4.22.0, Firmware vSTM32Cube_FW_F2_v1.6.0. Configured to work with SD card in SDIO + FatFs mode without DMA. Recording to the card comes at a speed of 2.5 ...
Posted on June 14, 2018 at 23:28How to reproduce:1) Use STM32Cube FW_F4 V1.21.0 (not tested on other versions)2) Set up SDIO 1-bit mode with default parameters.3)4) Set up FatFS with SDIO driver with default parameters.5) Set 'Use dma template'=enab...
Hi guys,I'm using an stm32f427 interfaced with an external SDRAM by mean of FMC controller.The controller is configured with SDRAM clock period = 2 x HCLK periods and to support burst read (RBURST bit = 1).It's not clear to me how to set the RPIPE pa...
I am doing C++17 development on the STM32L4. The register storage class specifier has been deprecated for quite some time in C++ and is now forbidden. It seems to be used extensively in the STM32L4xx ADC LL interface. This causes quite a large num...
Dear communityI am trying to make a timer/counter reset it's counter value on a falling edge and then hold the value until a rising edge (see attached picture for illustration). I am at the moment working on a L152, but I might soon be working on a ...
Hello, I'm trying to use example code provided by X-CUBE-IAP-USART package to develop IAP FW for STM32L0xx device. I'm using STM32L073 Nucleo64 board for development.When I send compiled FW using TeraTerm's YMODEM protocol nothing happens. Only thing...
