STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
1) Please mention how to Count pwm pulse for drv8825 stepper motor drive interface for precision movement .2) Which is the best method to control stepper motor i a) built-in pwm b) toggle an LED with microsecond delay.
i used isochronus transfert , and uncompressed video form i have attached a usb trace thanks
Hello, Everyone!I found issue with using my LCD (via i8080 mode) with FMC. My display requires HOLD after DATA set from 15 ns time. But in all FMC modes HOLD fixed and it 1 FMC CLK. For my STM32H743 at 400 MHz - I set FMC clock 200 MHz. It is HOLD = ...
Posted on May 22, 2018 at 18:44Hi to all.I'm trying to use I2C peripheral of STM32F103C8T6. I'm using a BluePill board. First of all, I know that this problem was published in other forums and so, but after trying other solutions, I didn't find the ...
Posted on April 30, 2018 at 18:19HiI'm trying to write some test data to SD card by DMA with Nucleo-F767Zi.Every 100ms I write 20 blocks to SD card by calling the HAL_SD_WriteBlocks_DMA() method.I have a counter to record how many times the HAL_SD_W...
When I make a post, I have to click at least three links to get back here. Hitting the back button only brings me to some sort of "ping timeout" page. Please either increase the timeout, or provide links back to the top. Links back to anywhere fro...
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...
